Catalog

YOKOGAWA Supplies A Complete Line

of Precise Panel Meters . . .

RoHS compliant

Elapsed Time Meters

Devices will match the frequency of AC

power systems. Six-digit counters

record hours, tenths of hours, minutes

and tenths of minutes. Reset or non-

reset models available.

Horizon Line Panel Meters

These meters possess the same

precision qualities as New Big Look.

In addition, Horizon Line panel meters

can be front or rear mounted on panel.

New Big Look Panel Meters

These meters feature extra-wide scales,

big bold numerals above the scale and

divisions for unobstructed reading.

Tapered needle-sharp pointers and

shadow-free acrylic covers help to

pinpoint values. Available in taut band

and pivot and jewel types. Gasket sealer

gives New Big Look dust and moisture

resistant design. (Except 11⁄2").

Stylist Series Panel Meters

Available in Window mount or Surface

mount styles. Optional bezels for

Surface mount permit rear panel

mounting. Standard movement torque to

weight ratio is approximately 4 times

greater than most other manufacturer’s

high torque versions.

Thin edgewise meters

Our thin element design provides the

maximum performance in the smallest

of spaces. Available in 11⁄2" to 31⁄2" sizes

for vertical or horizontal mounting.

Edgewise Meters

YOKOGAWA’s answer to the squeeze

for space problem. This design allows

meters to be mounted vertically or

horizontally. They can stand alone or be

stacked in space-saving clusters. Built-

in magnetic shielding prevents

interference among meters and removes

the burden of special calibration.

YOKOGAWA Offers These Advantages . . .

Dust Resistant Construction

YOKOGAWA Big Look panel meters,

except 11⁄2", feature gasketed

construction to seal out dust and other

air-suspended damaging particles.

Application is ideal for adverse

environments. Special dust resistant

features are included on all YOKOGAWA

New Big Look meters, (except 11⁄2").

For more severe applications, to meet

UL-1437 or IEC 144 requirements, other

models are also available upon request.

Back-Of-Panel Mounting For

Horizon Line

Horizon Line panel meters can be

mounted either behind or in front of the

panel. Behind-panel mounting is easy

. . . just remove snap-off mask and

mount. No special mounting hardware

or bezel is required. This design feature

improves panel appearance . . . saves

time and money. When illuminated

scales are required, simply position light

source as shown, or in any suitable

position along the edge of the

instrument.

Clean, Readable Case Design

Provides Extra Safety

YOKOGAWA’s brand New Big Look and

Horizon Line panel meters are designed

to provide attractive styling, quick, sure

readability for any application . . . and a

built in safety feature to help you meet

national safety requirements. If you must

remove the acrylic cover, you have to

remove the instrument itself from the

panel in order to reach the special safety

screws holding on the cover. Removing

the meter prevents shock hazard. This

safety feature is standard on all New Big

Look and Horizon Line meters. All

windows and bases are UL94V0 rated

(non-flammable)

Gasket Sealing Design Establishes A New

Industry Standard

Dust resistant construction is now a standard feature

of all New Big Look panel meters 21⁄2"-41⁄2" only.

YOKOGAWA's unique gasket sealing design eliminates

the need for a crimped bezel, providing for quick

modification and scale changes while maintaining the

integrity of the meters.

Suspension

Taut Band

Taut band is a means of suspending the

moving mechanism between two ribbons of

metal, obviating the need for pivots, jewels

and control springs found in conventional

mechanisms. The absence of friction

resulting from this permits greater sensitivities

and provides more rugged meters.Common

failures of conventional meters subjected to

shock testing are cracked jewels and/or

blunted pivots. Taut band, without pivot and

jewels, consequently, will withstand shock in

excess of that specified for pivot and jewel

meters. For example, ANSI Specifications for

panel meters require 50G shock. Taut-band

meters will withstand 100G shock.

Pivot and Jewel

In this design the coil and pointer are

supported by polished steel pivots at each

end which fit into jewel bearings. Pivot and

jewel meters are recommended for high-

vibration environments because of the

mechanism’s inherent stability and strength.

Accuracy and repeatability are almost equal

to the taut-band’s, and good performance

from the pivot and jewel construction is the

reason for its long popularity. Don’t specify

pivot and jewel meters for applications that

involve high shock, but do take advantage

of this meter’s ability to withstand vibration.

High-sensitivity DC Voltmeters

Standard DC voltmeter sensitivity is 1000

ohms/volt. Expressed differently, 1000

ohms/volt sensitivity means that the meter

draws approximately one milliamp full-scale

current.

Occasionally lower current drains are

necessary, hence higher sensitivities may be

required. The table below compares available

sensitivities, maximum self-contained

voltages, and approximate full-scale currents.

The voltage range could be extended by

using external resistors.

Expanded-scale Voltmeters

For very close monitoring of voltages, Zener

diode expanded scale voltmeters are

available in 31⁄2- and 41⁄2-inch sizes for AC and

DC ratings. Accuracy is ±0.5% of full-

scale value. Standard voltage spans are

listed in “Ratings.”

Expanded scale voltmeters can be

furnished for any mid-span values from 12

to 300 volts. Minimum span is 16% of

mid-span value.

Frequency Effect — AC Meters

Iron vane voltmeters are sensitive to

frequency and should not be used on

frequencies other than design frequency.

(Standard voltmeters are calibrated at 60

Hertz. Used at 50 Hertz, accuracy becomes

±21⁄4%. There are also 150- and 300-volt

ratings listed which are calibrated at 400

Hertz). For calibrations at frequencies other

than 60 and 400 Hertz, refer to factory.

All Iron-vane ammeters (which produce a

conventional scale distribution with divisions

crowded in lower third of scale) from 10

milliamperes to 50 amperes are virtually

unaffected by a change in frequency; e.g., a

stock ammeter (calibrated at 60 Hertz) when

used at 400 Hertz incurs an additional error of

only .5 percent full-scale. If used on 1000

Hertz, the additional error is 4 percent. We

recommend use of stock (60 Hertz) ammeters

on any

frequency in the range of 25 Hertz to 400

Hertz. For calibration at frequencies outside

the 25-Hertz to 400-Hertz range, refer to

factory or use a rectifier-type AC ammeter.

Rectifier-type Meters

Rectifier-type meters differ from iron-vane

mechanisms in that:

•They provide a nominally linear (DC) scale

rather than conventional iron-vane distribution

which has a slight crowding at low end of

scale.

•AC current measurements of microamperes

and milliamperes at minimum power

consumption are permitted.

•AC voltmeters of higher sensitivity

(ohms/volt) than iron-vane types can be

made.

•Frequency response of rectifier type meters

is essentially flat from 20 to 1,000 Hertz (1%

effect from reference to 60 Hertz).

Rectifier-type meters employ a full-wave

rectifier and are available in ratings of

500µA to 30A.

Suppressed-zero DC Meters

DC meters can be mechanically suppressed

up to 20% of end-scale value. However,

additional errors are introduced by sup-

pressions; e.g.,

Errors at 20% suppression = ±3%

of end-scale

Many process transmitters in use today

provide a 4-20mA signal (occasionally 10-50

mA or 1-5mA) and require a suppressed-zero

meter with operating zero set. These are

known as “live-zero” and are standard.

Higher Accuracy

Standard calibration accuracy is ±2% of full

scale. DC meters can be calibrated to ±1% of

full scale as a special model in 31⁄2" and 41⁄2"

with mirrored scale.

Conduit Mounting Case — 21⁄2-inch New Big

Look Meter

Available only for 21⁄2-inch Type 250 panel

meters, for indoor or outdoor use, the conduit-

mounted case provides protection to the meter

under severe environmental conditions. The

conduit case is both sealed and weatherproof

and is pre-drilled, ready for mounting of

separately ordered panel meters. Assembly of

meter into case is done by purchaser. (Drawing

No. 2579K10700.)

Specifications

Accuracy: All DC and AC iron-vane; ±2%

of full-scale, AC rectifier type; ±3%

of full scale (with 60 Hz sine wave at 25º C).

When standard 60 Hz iron vane ammeters

are used at the extreme limits of 20 or 400

Hz, additional error (approx. .75%) may be

experienced. Expanded-scale voltmeters;

±.5% of full scale value.

ANSI Specification: All meters meet ANSI

Specifications C-39.1.

Overload: Voltmeters (AC and DC) - 50%

momentary, 20% sustained. Ammeters

(AC and DC) momentary: 10 times the

rated current for 10 consecutive intervals

of .5 second with a 1 minute interval

between successive applications; sustained:

20% for six hours.

Scale Data: 90 degree rotation.

6. Suppressed-zero (DC only) (20% Suppression Max.) ....................................... X N/A X X

Suppressed-zero meters have greater error than standard zero-left meters.

Normally suppressed-zero units are supplied with zero adjustment. They

can be furnished with inoperable zero adjustment upon request.

7. Offset-zero ratings and scale (DC only)............................................................. X N/A X X

8. Nonstandard lead resistance ............................................................................. X N/A X X

Standard two-way shunt lead resistance for shunt-rated ammeters, 50 or

100 millivolt, is 0.065 ohms. Normally these meters can be used with a

wide range of lead resistances with only very small additional errors.

However, if calibration for a specific value of lead resistance other than

0.065 ohms is required, contact factory.

9. Calibration for mounting at a specific angle...................................................... X X X X

Special calibration not required for meters mounted 0 to 19 degrees from

vertical position.

Configurations

The mounting studs on the New

Big Look, Horizon Line and Stylist

Series Surface Mount can be

ordered to fit your existing panel

openings at no extra cost. These

cases are interchangeable with a

wide variety of competitive

instruments. Optional stud-

placement configurations are

shown at right and a cross-

reference of many replacement

instruments are listed on the next

page. This built-in

interchangeability eliminates the

need for drawing changes,

setups, and redrilling of panels . . .

and it solves your instrument

replacement problems.
