Control

In vast contrast to other self-

contained analog sensors, this

new and smaller 30 mm,

SUPERPROX® Model SM906

sensor series offers mounting

convenience, broad functionality

and a selection of three analog

sensing spans encompassing a

few inches from the sensor to as

far away as 26 feet. Depending

on the model selected and the

distance or level of the material

being measured or controlled,

the sensors offer analog spans of

1 m (39"), 2 m (79"), and a long

span of 8 m (26'). The capability

is enhanced further with the

shortest deadbands in the

sensing industry of 51 mm (2"),

120 mm (4.7"), and 203 mm (8"),

respectively.

As shown in the Model Refer-

ence Guide, the SM906 series of

ultrasonic analog sensors gives

the user a wide selection of

factory-configurable functionality

to maximize the sensor’s

efficiency in specific analog

sensing applications. In addition

to the analog sensing span, the

user may select a 0 to 10 VDC or

4 to 20 mA output that is either

directly or inversely proportional,

output state for loss of echo and

power up, and response time.

Also, a broad selection of

sensing functionality configura-

tions, with foreground and/or

background suppression, makes

possible optimum sensing

discrimination. This includes,

for example, the capability of

monitoring levels in a tank while

ignoring the paddles on the tank

agitator.

The 30 mm housing, 60%

smaller than other analog

sensors with equal functionality,

provides a package for the

SM906 that is easily installed,

without positioning limitations, in

covers and other hard-to-mount

areas. The models in this series

are equipped with a pushbutton

to set the sensors’ near and far

span limits. When it is impractical

to use the pushbutton for setting

the long-range limits, an optional,

hand-held, setup/display

accessory is available. The two

limits can be set for a span to

either encompass the full range

of the sensor or create a span as

small as desired for precise level or

distance control. A typical example of

precise level control is when the applica-

tion calls for maintaining a constant fill

level in a filler machine. In this example,

the analog output provides a means of

controlling the product flow into the filler

as the filler speed changes. The analog

output may provide a means for control-

ling the speed of other machinery as

well as regulate the movement of control

valve actuators. The analog output may

also connect directly to programmable

controller analog input modules for

performing complex loop control or

simple status (e.g., distance measuring)

monitoring functions. All control limits

are stored in nonvolatile memory and

thus are retained if power is removed

from the sensor.

Unlike other sensing technologies,

these sensors are capable of detecting

all materials, liquid, granular and solid,

regardless of color, shape and composi-

tion, transparent or opaque, including

powder, food products, grains, chemi-

cals, pharmaceuticals, oils, plastics and

objects that change colors. The

threaded housings are available in ether

ULTEM® plastic or SS303 stainless steel

which are epoxy encapsulated to with-

stand shock and vibration. Both hous-

ings are sealed to withstand dusty, dirty,

clean-in-place, noncondensing humidity,

high-pressure washdown environments

and they are virtually unaffected by

changing light conditions, colors and

noise. In meeting NEMA 4X and IP67

industry standards, the sensors resist

most acids, bases and oils, including

most food products. All the sensors in

this model series are CE certified.

1-meter- and 2-meter-

span models

For purpose of definition, the standard

1-meter-span models are identified in the

Model Reference Guide as the Model

SM906A-1 and SM956A-1 series sensors

and the 2-meter-span models are

identified as the Model SM906A-4 and

SM956A-4 series sensors. Respectively,

these models provide for analog output

sensing from 50.8 mm to 1 m (2 to 39")

and 120 mm to 2 m (4.7 to 79"). The 96

mm (3.78") length of the connector model,

excluding the connector/cable assembly,

adds to the sensor’s installation conve-

nience. Operating on a sonic frequency of

200 kHz, these sensors have a standard

response time of 25 ms and 35 ms for the

1- and 2-meter-span models, respectively

with others available as shown in the

Model Reference Guide. The FDA

approved silicone rubber transducer,

while used to couple the ultrasonic

energy to the air, is also resistant to most

acids, bases and oils and food products.

Selected 1- and 2-meter-span sensors

have DeviceNet capability.

Various functional choices plus the

mounting convenience of a 30 mm

housing combine to achieve reliability

and cost effectiveness for these models in

the detection of moving object positions

in specific sensing applications. These

include: monitoring and controlling levels

of liquids and solid materials in bins and

filler bowls, controlling container flow on

mass conveyors, monitoring and control-

ling roll diameters and speeds, webs of

paper and fabrics, extrusion widths,

tension, dancer loops and valve posi-

tions, as well as the modulation of

variable-speed motors, pumps and

winding/unwinding equipment.

For 1-meter-span, analog-output

sensing applications that require mea-

surement and control capability in severe,

corrosive-type environments, the Model

SM906A-7STS and Model SM956A-7STS

series models have an SS303 stainless

steel housing and an SS304 stainless

steel-faced transducer. With an analog

sensing span of 120 mm to 1 m (4.7 to

39"), these sensors provide reliable

operation in either the detection of certain

chemicals and corrosive materials or

where caustic cleaning solutions are used

in washdowns of machinery and equip-

ment in close proximity to the sensor. For

out-of-doors, analog-sensing applica-

tions, where cold weather is a factor, this

corrosion-resistant model series provides

reliable operation in temperatures as low

as -10° C (14° F).

8-meter,

long-span models

The Model SM906A-8 and Model

SM956A-8 series represents the only

analog sensors on the market that offers

the combination of shortest deadband,

longest span and smallest package. As

indicated in the Model Reference Guide,

these sensors measure and monitor the

position and level of objects over a

sensing span of just 203 mm (8") to 8 m

(26'). With this shortest dead- band, the

need to position the sensor at great

distances from the object, typical of

most long-span sensors, is eliminated.

At only 116.31 mm (4.579") in length for

the cable-style model, a fraction of the

size of other long-span sensors, these

30 mm diameter sensors are easily

mounted in covers and other tight

spaces in the plant. They operate on a

sonic frequency of 75 kHz with a

standard response time of 250 ms and a

minimum response time of 150 ms. Other

response times are available. An epoxy

transducer face, in addition to coupling

the ultrasonic energy to the air, allows the

sensor to perform in a wide range of

harsh environments including those

involving most acids, bases and oils.

By virtue of the 75 kHz frequency,

the sensor’s wide, 20-degree beam is

especially effective in sensing the tank

or bin levels of various types of liquids,

solids and granules. This includes

applications involving the blending of

ingredients and the processing of food

products and pharmaceuticals, as well as

the treatment of water and sewage. For

outdoor analog output applications, the

sensors have temperature compensation

for operation in temperatures ranging

from -20° to 60° C (-4° to 140° F). In

applications where high sound absorp-

tion conditions exist in the material being

detected, (e.g., tiny plastic pellets), and

either the 1- or 2-meter span model

sensor becomes unreliable because of

lost energy, the more powerful long-span

SM906 can provide the solution when

used in the shorter-span distances.

Operation

The SUPERPROX® Model SM906

series is a self-contained, pulse-echo

device that both transmits and receives

sonic energy within the specified analog

span. Operating on 15 to 24 VDC, these

sensors use the latest ultrasonic sensing

and microprocessor technology that

allows the sensor to ignore all surround-

ing sonic interference and detect only

the designated object.

During operation, the sensor monitors

the distance to an object or level while

generating a proportional analog output

relative to the two analog span limits.

When an object is within the analog

span, the analog output value changes

proportionally in relation to the analog

span limits. For example, if the object is

half way between the analog span limits,

the output is either 5 Volts or 12 mA,

depending on the output model se-

lected. The output range adjusts to the

size of the analog span and remains

proportional regardless of where the

limits are set for the analog span.

The sensors are equipped with a

multicolor sensing status LED and a red

output LED. The multicolor LED indicates

where the level or target position is

relative to the span limits. It is green

when the object is between the analog

span limits, red if closer than the near

span limit, and amber if farther than the

3-118

far span limit. The red LED indicates the

relative value of the analog output and

varies in intensity according to the

output. The higher the current or voltage

output, the brighter the red LED.

As shown on this page, Hyde Park

offers both direct and inverse propor-

tional analog output models for continu-

ous sensing applications.

How does it work?

During setup and operation, these

SM906 series ultrasonic sensors

continually and accurately measure the

elapsed time of every pulse echo

reception between each pulse transmis-

sion. The transmitted pulse begins a

time clock to register the elapsed times

for the received pulse echoes. Given the

elapsed time, the sensor software

calculates the distance traveled out to

the object or surface and back to the

sensor, using the formula, D = Tvs/2,

where: D = Distance from the sensor to

the object; T = Elapsed time between

the pulse transmission and its echo

receptions; and Vs = the Velocity of

sound, approximately 1100 feet per

second.

During operation, the calculated distance (D) between the sensor and the object is

compared to the distances between the sensor and the analog span limits. These

limits are shown in the illustration below as Dwi and Dwo. If D is within the analog

span limits, according to the selected sensing functionality configuration, a propor-

tional output value for D, relative to the analog span limits, is generated.

Sensing Functionality

Configuration

There are four sensing functionality

configurations available, through model

selection, to provide a Model SM906

series sensor with optimum sensing

discrimination. This means the sensor

is capable of detecting objects at certain

distances and ignoring objects at other

distances. An example would be in the

monitoring of a level in a tank while

ignoring the paddles on the tank

agitator which would be closer than

the near span limit.

Each configuration employs a different

algorithm to determine which echo

returns are either accepted or ignored

over the specified sensing range. Thus,

these four configurations enable the

sensor series to address a multitude of

continuous-sensing, process-control

applications.

Use the following four illustrations as a

guide in selecting the functionality best

suited for the sensing application.

Configuration: “00” - Standard:

No foreground or background

suppression

With this configuration, the sensor

processes only the first echo received

from anywhere within the sensing span.

With this configuration, the sensor

processes only the first echo received

from an object. If the first processed

echo from the object is closer than the

near span limit, the echo is ignored and

not processed. If the first processed

echo from the object is between the near

span limit and the sensing range, the

echo is processed and the analog

output value is updated.

Analog Output

Response Function

The analog output value is derived

from the sensor response time and the

object distance from the sensor. The

“standard” response for the one-meter

range sensing model is 25 ms and its

analog output value is derived from the

average of the last two echo returns.

The “fast” response time for a one-meter

range sensing model is 15 ms and its

analog output value is derived from the

last echo return. For sensors with other

response times, the analog output value

reaches 95% of the final output value in

the stated response time using an

exponential averaging function.

Setting the Analog Span

Limits

Located on the backside of the sensor,

the SETUP pushbutton is used to set

both the near and far span limits.

Depress the SETUP pushbutton (the

multicolor LED rapidly flashes amber to

indicate the pushbutton is being

pressed) until the multicolor LED flashes

green in about 3 seconds, and then

release the SETUP pushbutton, The

multicolor LED continues flashing green

indicating the sensor is waiting for the

first span limit. Align a flat object parallel

to the sensor face at the desired

distance position for either (near or far)

span limit, and press the SETUP

pushbutton once. Upon release of the

SETUP pushbutton, the multicolor LED

flashes amber indicating the first span

limit is set and the sensor is waiting for the

second span limit. Align a flat object

parallel to the sensor face at the desired

position for the second span limit and

press the SETUP pushbutton once. Upon

release of the SETUP pushbutton, the

multicolor LED turns to the color that

indicates where the object is located. The

sensor has no time-out for setting limits.

While the SETUP pushbutton is

depressed, the multicolor LED turns

amber to indicate the sensor detects the

object. If the sensor does not detect the

object, the multicolor LED is red while

the SETUP pushbutton is depressed,

and when the SETUP pushbutton is

released, the multicolor LED flashes red

2 seconds. After flashing red for 2

seconds, the sensor requests that span

limit again by flashing green for the first

span limit or flashing amber for the

second span limit.

Once set, span limits are saved in

nonvolatile memory and thus are

retained when power is removed from

the sensor.

Output State for Loss of

Echo Selections

As shown in the Model Reference

Guide, four selections are available to

address loss of echo conditions for

specific applications.

Selection “0” or “1” - Without

Signal Hold on Loss of Echo

On power-up or when no echoes are

detected for one second, for the 1- and

2-meter sensing span and 4 seconds for

the 8-meter sensing span, the analog

output will go to a minimum value for

selection 0 or a maximum value for

selection 1.
