Terminology
Operating Range
The difference between the minimum decreasing-pressure low point (PB) and the maximum
increasing-pressure high point (PH) setting values.
Size
Pressure switches and vacuum-pressure switches
Maximum value of the operating range.
Vacuum switches
Minimum value of the operating range.
Operating Point on Rising Pressure (PH)
Pressure switches
The upper pressure setting at which the pressure switch actuates the contacts on rising pressure.
Vacuum switches
The lower vacuum setting at which the vacuum switch resets the contacts on rising vacuum.
Operating Point on Falling Pressure (PB)
The pressure at which the switch output changes state on falling pressure.
Switches with fixed differential
Depending on the switch, either the high or low operating point is adjustable, and the other operating
point follows. The window is fixed.
Switches with adjustable differential
An adjustable differential allows independent setting of both operating points.
Differential
The difference between the operating point on rising pressure (PH) and the operating point on falling
pressure (PB).
Spread
For dual-stage switches, the spread indicates the difference between the two operating points on rising
pressure (PH2 and PH1) and, for vacuum switches, the difference between the two operating points on
falling pressure (PB2 and PB1).
Differential-Pressure Sensing
Switches for differential-pressure sensing measure the difference between two pressures.

Maximum allowable pressure per cycle (Ps)
The maximum pressure level per cycle that the switch can withstand for optimum service life.
Surge
A surge is a high rate of rise in pressure, normally of short duration, caused by starting a pump or by
opening and closing a valve. Depending on frequency and duration, surge can reduce service life.
Extremely high rates of rise in pressure can be damaging even if they are within the limits of the
maximum allowable pressure.
Destruction pressure
Also called burst pressure, the destruction pressure is the maximum rated pressure that the switch can
withstand before its destruction—for instance, through rupturing or component failure.
Accuracy (switches with setting scale)
The tolerance between the point at which the switch actuates its
contacts and the value indicated on the setting scale. Where very
high setting accuracy is required (initial installation of the product), it
is recommended to use separate measuring equipment (pressure
gauge, etc.).
Repeat Accuracy (R)
The tolerance between two consecutive switching operations
Drift (F)
The tolerance of the operating point throughout the entire service life
of the switch.
Maximum Allowable Pressure
The maximum value of an accidental pressure surge of very short
duration (a few milliseconds).
Example 1: With destructive (burst) pressure level
Without damping device

Selecting a Pressure Switch
The deciding factors in the selection of a pressure switch for use on control circuits1 depend on the
requirements of the application. Consider the following requirements to help determine the appropriate
catalog number for your application.
1. Setpoints: Do you want to control/monitor one setpoint or two?
2. Fluids: What fluids do you want to control?
Ensure that the wetted parts of the switch are compatible with the system fluid.
3. Pressure Range: What pressure range does the system experience?
Note: Select pressure settings that fall within the middle 80% of the pressure range. The pressure
applied during a normal cycle should never exceed the maximum range value listed for the switch.
Pressure surges should be less than the maximum allowable pressure listed for the switch.
4. Surges: How frequent are surges in your system, and what is their maximum pressure level?
Applications experiencing frequent or high-pressure surges may require a device with a higher
pressure range.

XML Electromechanical Pressure Switches
Introduction
XML pressure and vacuum switches for control circuits are used to control the pressure of hydraulic
oils, fresh water, sea water, air, steam, corrosive fluids, or viscous products, up to 7250 psi (500 bar).
•XMLA pressure and vacuum switches have a fixed differential and are for detection of a single
threshold. They incorporate a 1 C/O single-pole contact.
•XMLB pressure and vacuum switches have an adjustable differential and are for regulation
between two thresholds. They incorporate a 1 C/O single-pole contact.
•XMLC pressure and vacuum switches have an adjustable differential and are for regulation
between two thresholds. They incorporate two C/O single-pole contacts.
•XMLD pressure and vacuum switches are dual-stage switches, each stage with a fixed differential,
and are for detection at each threshold. They incorporate two C/O single-pole contacts (one per
stage).
Setting
XMLA: Pressure and vacuum switche s with fixed differential
•Rising pressure—Operating point PH is set by adjusting the red screw (1).
•Falling pressure—Operating point PB is not adjustable.
The difference between the trip and reset points of the contact is the inherent differential of the switch
(contact differential, friction, etc.).
XMLB and XMLC: Pressure and vacuum switches with adjustable differential
When setting the pressure and vacuum switches, first adjust the operating point on rising pressure
(PH), then the operating point on falling pressure (PB).
•Rising pressure—Operating point PH is set by adjusting the red screw (1).
•Falling pressure—Operating point PB is set by adjusting the green screw (2).
XMLD: Dual-stage pressure and vacuum switches with fixed differe ntial for each
threshold
Operating point on rising pressure of stage 1 and stage 2
•First stage operating point on rising pressure (PH1) is set by adjusting the red screw (1).
•Second stage operating point on rising pressure (PH2) is set by adjusting the blue screw (2).
Operating point on falling pressure
•The operating points on falling pressure (PB1 and PB2) are not adjustable.
•The difference between the trip and reset points of each contact is the inherent differential of the
switch (such as contact differential or friction).

Function
Pressure and vacuum switches control or regulate pressure or vacuum levels in hydraulic or
pneumatic systems. They transform the pressure change into a digital electrical signal when the preset
operating points are reached.
Switches for control circuits
Switches with control-duty rated electrical contacts, designed for control of contactors, relays, power
valves, PLC inputs, etc.
Switches for power circuits
Switches with power electrical contacts (1, 2, or 3 pole) designed for direct switching of single-phase or
three-phase motors (pumps, compressors, etc.).
Pressure switch operating principle
Fixed Differential: Detection of a Single Threshold
Adjustable Differential: Regulation between Two Thresholds
Dual-Stage: Detection of Two Thresholds
Dual-stage switches allow two distinct levels of control to be monitored with one device. Each stage
allows detection of a single threshold with a single setting point (fixed differential). Both these points
can be independently adjusted. However, for both stages, the differential between the high point and
the low point (PH1–PB1 and PH2–PB2) is fixed and depends on the construction of the switch.
Fixed differential switches
have a single adjustable
setting point (either PH or
PB). The differential
between the high and low
points (PH–PB) depends
on the construction of the
switch. It is not adjustable.

Vacuum switch operating principle
Detection of a single threshold
The switches for detection of a single threshold (fixed differential) have a single adjustable setting point
(PH). The differential between the high and low points (PH–PB) depends on the inherent characteristics
of the switch. It is not adjustable.
Regulation between two thresholds
The switches for regulation between two thresholds (adjustable differential) have both a high point
setting (PH) and a low point setting (PB). Both of these points can be independently adjusted.
Detection o f two th res h ol ds
The dual-stage switches, for detection at each threshold, have an adjustable high point setting for each
stage (PH1 and PH2). Both of these points can be independently adjusted.
For both stages, the differential between the high point and the low point (PH1–PB1 and PH2–PB2)
depends on the inherent characteristics of the switch. It is not adjustable.
Maximum allowable accidental pressure
The maximum accidental pressure of XML switches is equal to at least 2.25 times the switch size.
If accidental overpressures occur and their duration is less than 50 milliseconds, the pressure damping
device incorporated in the XML switches (sizes 10 bar and greater) reduces the effect.

Selecting the switch size
After establishing the type of switch required for the application (single threshold detection or
regulation between two thresholds), the selection of its size depends on the following criteria:
•the differential: difference between the high point (PH) and the low point (PB),
•the maximum pressure allowable per cycle,
•repeat accuracy, precision and minimum drift.
Selecting a fixed differential pressur e switch for detecting a single threshold
Main criterion: minimum differential
Example: for a selected high point (PH) of 7 bar
Select an XMLA010••••• (the lowest size)
Main criterion: tolerance to overpressures
Example: for a selected high point (PH) of 12 bar
Select an XMLA035••••• (the highest size)
Main criterion: repeat accuracy, precision and minimum drift
Example: for a selected high point (PH) of 18 bar
Select an XMLA035•••••
XMLA010•••••
Differential = 0.5 bar
XMLA020•••••
Differential = 1 bar
XMLA035•••••
Differential = 2 bar
XMLA020•••••
Allowable accidental overpressure = 45 bar
XMLA035•••••
Allowable accidental overpressure = 80 bar
As a general rule, avoid working at
the upper or lower limits of the
operating range.

(PB)
The pressure at which the switch contact
changes state on falling pressure.
The lower point (PB) is not adjustable
and is entirely dependent on the high
point setting (PH) and the inherent
differential of the switch.
Differential PH–PB = inherent differential
The difference between the operating
point on rising pressure (PH) and the
operating point on falling pressure (PB).
This point is not adjustable, so the value
of the differential is fixed.
It is the inherent differential of the switch
(contact differential, friction, etc.).
Example Operating point on rising pressure (PH) is
40 bar (set value at which the contact
changes state on rising pressure).
The operating point on falling pressure
(PB) is 28 bar (fixed value at which the
contact returns to its original state).
Conclusion:
the differential is 40 – 28 = 12 bar.

Adjustment
range of
high point
(PH1 or PH2)
Defined by the difference between the
minimum and maximum high point (PH1
or PH2) setting values for each stage.
For a high set point (PH1 or PH2), the
lower point (PB1 or PB2) is fixed and
cannot be adjusted.
For a low set point (PB1 or PB2), the
higher point (PH1 or PH2) is fixed and
cannot be adjusted.
Operating
point on
rising
pressure
(PH1 or PH2)
The upper pressure setting at which the
pressure or vacuum switch actuates the
contact, for each stage, on rising
pressure.
Adjustable throughout the range on
rising pressure.
Operating
point on
falling
pressure
(PB1 or PB2)
The pressure at which the switch
contact changes state, for each stage,
on falling pressure.
The lower point (PB) is not adjustable
and is entirely dependent on the high
point setting (PH) and the inherent
differential of the switch.
Differential PH–PB = inherent differential
The difference between the operating
point on rising pressure (PH) and the
operating point on falling pressure (PB),
for each stage. This point is not
adjustable, so the value of the
differential is fixed. It is the inherent
differential of the switch (contact
differential, friction, etc.) for each of its
two stages.
Example:
stage 1 =
segment EF
stage 2 =
segment GH
For stage 2 (segment GH):
Operating point on rising pressure (PH2)
is 20 bar (set value at which contact 2
changes state on rising pressure). The
operating point on falling pressure (PB2)
is 14 bar (fixed value at which contact 2
returns to its original state).
Conclusion: for stage 2, the differential
is: 20 – 14 = 6 bar.
Repeat the same procedure for stage 1
(segment EF).

9012G Pressure Switches
The 9012G pressure switches are UL Listed and CSA Certified as industrial control equipment. They
are used to interface pneumatic or hydraulic systems with electrical control systems by opening or
closing electrical contacts in response to pressure changes in the system. They have outstanding
repeatability and drift performance. Their efficient design uses durable, low mass components for
excellent performance under heavy duty vibration and shock conditions.
The 9012G pressure switches line offers devices with either diaphragm or piston actuators—for
optimum life, versatility, and speed of operation. A variety of modifications are available (see page 91).
Features include the following:
The 9012G diaphragm switches range from 0.2–675 psi falling pressure. Buna-N diaphragms and
zinc-plated steel flanges are standard. Diaphragms of Viton® flourocarbon or ethylene propylene are
available as well as stainless steel flanges.
The 9012G piston actuated switches range from 20–9,000 psi falling pressure. They have sealed
pistons and can be used on air, water, oil, or any media compatible with the actuator material. The
switches come standard with stainless steel pistons and housings, Viton diaphragms and O-ring seals,
and Teflon® retaining rings. Ethylene propylene diaphragms and O-ring seals are also available.
The 9012G industrial pressure switches are available as open type or in NEMA Type 1 enclosures.
The backplate is steel with a plastic cover. Open devices in pressure ranges up to 250 psi are available
with internal- or external-threaded pressure connectors, ideally suiting them for panel mounting.
The 9012G machine tool pressu re switches with NEMA Type 4, 4X, or 13 (IP66) cast aluminum
enclosures are UL Listed and CSA Certified as industrial control equipment. They are also UL Marine
Listed for use on vessels greater than 65 ft long where ignition protection is not required.
The 9012G machine tool switches are also available in NEMA Type 7 & 9 cast aluminum enclosures.
These are UL Listed for use in Class I, Divisions 1 and 2, Groups C and D, and Class II, Divisions 1
and 2, Groups E, F, G hazardous locations.
Application and General Information
9012 pressure switches can generally be used in any application where electrical contacts must open
or close in response to a system pressure change, within the electrical and pressure ratings of the
switch. Pressure switches are used in a wide variety of applications such as the following:
Pressure switches typically perform one of the following two functions:
•Monitoring the pressure in the system. The switch can be used either as an interlock that
sequences operations in an automatic system, or to give an audio or visual signal, typically an
alarm of an undesired condition, at predetermined pressures. A switch with a fixed differential is
generally used in these applications.
•Controlling the pressure in the system by starting and stopping a pump or a compressor at
predetermined pressures. A switch with an adjustable differential is usually needed in these
applications.
•High shock resistance •Dual numerical range scale (psi and kPa)
•High set-point stability •One or two SPDT double-break contacts
•Internal or external range adjustment •Adjustable or fixed (fixed) differential
•No drain line required •Single-stage, dual-stage, or differential-pressure
operation
•compressed air systems •stamping presses
•HVAC equipment •automatic grinders
•chillers •welders
•pumping systems •process equipment
•machine tools •molding machines

Introduction Industrial Pressure Switches
9012G Pressure Switches

Diaphragm Life
The elastomer diaphragms used on 9012G switches can withstand high speed cycling and wide
pressure changes. They can tolerate operating speeds up to 200 cycles per minute with no negative
impact on the life of the diaphragm.
Diaphragm life is affected by pressure medium compatibility. Standard diaphragms on 9012G devices
are Buna-N nitrile in zinc-plated steel flanges. Also available are Viton fluorocarbon and ethylene
propylene diaphragms, as well as Type 316 stainless steel flanges.
The diaphragm can withstand wide pressure changes on each operating cycle. However, the pressure
applied to the diaphragm during the normal operating cycle should never exceed the maximum value
listed in the Range column in the catalog listing. Regularly cycling the pressure above this value
reduces life considerably. If significant surges are common, or if pressures are higher than those listed
in the Range column, consider using a piston device.
Piston Life
For long piston life, the pressure medium should be filtered to keep foreign matter such as dirt and
chips out of the piston assembly. 9012G sealed piston devices are not recommended for use on dry
gas media, since this usage could cause some leakage past the seal. Depending on the gas, the
media pressure, and the rate of operation, the amount of leakage could render the switch inoperable.
(Note, however, that some weepage of the media is necessary to lubricate the seals. This small
amount of weepage does not indicate a problem.)
Surges
One of the most destructive conditions for a pressure switch is hydraulic surge. A surge is a high rate
of rise in pressure, normally of short duration, caused by starting a pump or by opening and closing a
valve. Extremely high rates of rise in pressure can be damaging even if they are within the limits of the
maximum allowable pressure.
To limit the effect of surges, the switch should be mounted as close to an accumulator and as far from
the pump or quick acting valve as possible. The 9012G piston actuated switches have a 0.020 in.
pressure orifice to help reduce the effects of minor surges. 9012G diaphragm actuated switches have
a 0.060 in. pressure orifice. A restrictor with a small orifice placed in the line between the switch and
the pump or valve will further help to protect the switch. Using a surge snubber such as the 9049A26 or
A26S will also protect the switch.
Vibration
Among other things, excessive vibration can cause contact bounce, chatter, or premature contact
transfer, especially when system pressure is near the operating point of the switch. Remote mounting
of the switch is the best way to avoid problems.
Use on Steam
Switches should not be applied directly on steam exceeding 15 psig. However, with steam capillary
tubing installed between the pressure connection and the switch, steam pressure up to 250 psig can
be applied—provided this does not exceed the maximum allowable pressure rating of the switch or the
maximum temperature rating at the actuator. Refer to the instruction bulletin supplied with the device.
Dual-Stage Operation
The 9012G dual-stage pressure switches provide two distinct levels of control from one device. These
switches are most commonly used where dual functions are required, or in sequencing applications
such as alarm-shutdowns.
Differential-Pressure Operation
The 9012G pressure switches for differential-pressure sensing can monitor changes in the difference
between two pressures. These unidirectional devices signal that a predetermined pressure difference
was reached, resulting from a widening or narrowing of the difference between two pressures.

Piston- vs. Diaphragm-Actuated Devices
Selecting between piston and diaphragm devices depends on several criteria:
•maximum allowable pressure
•range and differential
•surges
•medium (whether hydraulic or pneumatic)
Maximum allowable pressures for piston devices are much higher than for diaphragm devices. Most
diaphragm devices have a maximum allowable pressure of 850 psi or less, whereas all piston devices
have a maximum allowable pressure of 10,000 psi or more.
Range and differential for diaphragm devices are lower than for piston devices. Many applications call
for a low differential, such as 20 psi. This may exclude piston devices, which have a minimum
differential of 60 psi or more.
Surges are a part of every hydraulic system. While many are small and have only a small effect on the
switch, some are significant and can potentially destroy a pressure switch. Diaphragm devices are the
most sensitive to surges and are most easily damaged. Piston devices are more tolerant of surges and
last longer in the same application.
Hydraulic systems, which typically use oil-based media, are more demanding applications than
pneumatic systems. Pressure switches used in hydraulic applications typically experience higher
pressures, have wider pressure variations, and produce more surges, since the medium does not
compress. Pneumatic systems, which typically use air, place fewer demands on a system, since these
applications typically experience lower pressures and the medium can compress, cushioning the
effects of surges. Table 66 offers basic guidelines for determining the selection of a piston- versus a
diaphragm-operated pressure switch.
Technical Overview
Operating Points (Set Points)
Pressure switches have two operating points:
•Increasing pressure operating point (rising pressure)
•Decreasing pressure operating point (falling pressure)
These operating points are also called the set points of the switch.
Differential
The differential is the difference in pressure between the rising and falling pressure points. It can be
adjustable or fixed.
Range
The range refers to the pressure limits within which the operating points (settings) can be adjusted.
The range of the 9012G pressure switch is tied to the decreasing pressure operating point. Adding the
differential to the decreasing pressure operating point determines the increasing pressure operating
point.

Fixed Differential
To determine the operating range on rising pressure for a fixed differential switch, add the differential
to the decreasing pressure operating point.
For example, to determine the range on increasing pressure for a 9012GDW5 switch:
1. Range on decreasing pressure = 3 to 150 psi
2. Fixed differential = 6.0 ± 0.8 psi
3. Range on increasing pressure = 9 ± 0.8 to 156 ± 0.8 psi
Adjustable Differential
For adjustable differential switches, add the minimum differential to the low end of the range and the
maximum differential to the high end of the range.
For example, to determine the range on increasing pressure for a 9012GAW5:
1. Range on decreasing pressure = 3 to 150 psi
2. Adjustable differential = 6.0 to 30 psi
3. Range on increasing pressure = 9 to 180
During the normal operating cycle, system pressure should never exceed the upper limit of the range
when using a diaphragm actuated switch. This greatly reduces the life of the diaphragm. For optimum
life, operate the switch in the middle 80% of the range.
Maximum Allowable Pressure
Maximum allowable pressure is the pressure to which a switch can be subjected without causing a
change in operating characteristics, shift in settings, or damage to the device.
System pressure surges may occur during machine startup or from valve operation. Surges are not
normally detrimental to the life of a switch if the surge is within the maximum allowable pressure rating
of the switch. Diaphragm actuated switches should not be subjected to more than 10 surges per day.
More frequent surges greatly reduce the life of the diaphragm.

Differential-Pressure Operation
Pressure switches for differential-pressure operation are used to monitor the change in the difference
between two pressures. The 9012G differential-pressure switches are unidirectional devices and are
used in applications to signal that a predetermined pressure difference has been reached as a result of
a widening or increasing difference between the two pressures. They can also be used in applications
to signal that a predetermined pressure difference has been reached as a result of a narrowing or
decreasing difference between the two pressures.

Dual-Stage Operation
The 9012G dual-stage pressure switches are designed for use in applications where two separate
pressure operations must be controlled by a single pressure monitoring device. These controls are
most commonly used where dual functions are required or in sequencing applications such as alarm
shutdowns. The spread between the two stages is adjustable, but the differential between the high
(rising) and low (falling) operating points of each stage is fixed.
