YOKO GAWA Supplies A Co mplete Lin e

of Precise Pan el Meters . . .

Elapse d T ime Meters

Devices will match the frequency of AC

power systems. Six-digit counters record

hours, tenths of hours, minutes and

te nths of minutes. Reset o r non-reset

models available.

Horizon Lin e Panel Meters

These mete rs possess the same

precision quali ties as New Big Look.

In addition, Horizon Line panel mete rs

can be front or rear mounte d on panel.

New Big Look Panel Meters

These mete rs feature extra-wide scales,

big bold nume rals above the scale and

divisions for unobstr ucte d reading.

Tapered nee dle-sharp pointe rs and

shadow-f ree acrylic covers help to

pinpoint values. Available in taut band

and pivot and jewel types. Gasket seale r

gives New Big Look dust and moisture

resistant design. (Except 1

Edgewis e Meters

YOKOGAWA’s answer to the sque eze fo r

space problem. This design allows

mete rs to be mounted vertically or hor i-

zontally. They can stand alone or be

stacke d in space-saving clusters. Built-in

magnetic shielding preve nts inter ference

among meters and removes the burden

of special calibration.

YOKO GAWA Offe rs These Advantages . . .

Dust Resis tant Const ruct ion

YOKOGAWA Big Look panel meters,

except 11⁄2”, feature gasketed

construction to seal out dust and other

air-suspended damaging particle s.

Application is ideal fo r adverse

environments. Special dust resistant

feature s are included on all YOKOGAWA

New Big Look mete rs, (except 1

⁄

”).

For more seve re applications, to me et

UL-1437 or IEC 144 requirements, other

models are also available upon reque st.

Back-Of-Panel Mounting For

Horizon Lin e

Horizon Line panel mete rs can be

mounte d either behind or in front of the

panel. Behind-panel mounting is easy

. . . just remove snap-of f mask and

mount. No special mounting hardwa re

or bezel is required. This design feature

improves panel appearance . . . saves

time and money. When illuminate d

scales are require d, simply posi tion light

source as shown, o r in any suitable

position along the edge of the

instrument.

Clean, Readable Case Des ign

Provides Ext ra Safet y

YOKOGAWA’s brand New Big Look and

Horizon Line panel mete rs 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 instr ument itself from the

panel in order to reach the special safety

screws holding on the cover. Removing

the meter preve nts shock hazard. This

safety feature is standard on all New Big

Look and Horizon Line meters.

Gasket Sealing Design Establishes A New

Industry St andard

Dust resistant construction is now a standard feature of

all New Big Look panel mete rs 2

YOKOGAWA's unique gasket sealing design eliminates

the nee d for a crimped bezel, providing for quick

modification and scale changes while maintaining the

integr ity of the mete rs.

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 mecha-

nisms. The absence of friction

resulting from this pe rmits greater sensi tivitie s

and provide s more rugged meters.Common

failures of conve ntional mete rs subjected to

shock testing are cracke d jewels and/or

blunte d pivots. Taut band, without pivot and

jewels, conseque ntly, will withstand shock in

exce ss 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 bea rings. Pivot and

jewel mete rs 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 go od performance

from the pivot and jewel construction is the

reason fo r its long popularity. Don’t specify

pivot and jewel meters fo r applications that

involve high shock, but do take advantage

of this mete r’s ability to withstand vibration.

High-se nsitivi ty DC Voltmeters

Standard DC voltmeter se nsitivi ty is 1000

ohms/volt. Expresse d dif ferently, 1000

ohms/volt sensitivi ty means that the meter

draws approximately one milliamp full-scale

current.

Occasionally lower cur rent drains are

necessar y, hence higher sensitiv ities may be

required. The table below compares available

sensitiv ities, maximum self-containe d

voltages, and approximate full-scale currents.

The voltage range could be extende d by

using exter nal resisto rs.

Expanded-s cale Voltmeters

For very close monitoring of voltages, Zener

diode expanded scale voltmete rs are

available in 31⁄2- and 41⁄2-inch sizes fo r 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 f rom 12

to 300 volts. Minimum span is 16% of

mid-span value.

Frequency Ef fect — AC Meters

Iron vane voltmete rs are sensitive to

freque ncy and should not be used on

freque ncies other than design frequency.

(Standard voltmeters a re calibrated at 60

Her tz. Used at 50 He r tz, accuracy becomes

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

ratings listed which are calibrate d at 400

Her tz). For calibrations at freque ncies other

than 60 and 400 Hertz, refer to facto r y.

All Iron-vane ammeters (which produce a

conventional scale distribution with divisions

crowde d in lowe r third of scale) from 10

milliamperes to 50 amperes are virtually unaf-

fecte d by a change in frequency; e.g., a stock

ammeter (calibrate d at 60 Her tz) when used at

400 Her tz incurs an additional error of only .5

percent full-scale. If use d on 1000 Her tz, the

additional error is 4 percent. We recommend

use of stock (60 Her tz) ammeters on any

freque ncy in the range of 25 Hertz to 400

Her tz. For calibration at freque ncies outside

the 25-Hertz to 400-Her tz range, refe r to

factory o r use a rectifier-type AC ammeter.

Rect ifie r-t ype Meters

Rectifie r-type meters differ from iron-vane

mechanisms in that:

•They prov ide a nominally linea r (DC) scale

rather than conventional iron-vane distribution

which has a slight crowding at low end of

scale.

•AC cur rent measurements of microamperes

and milliamperes at minimum power

consumption are permit ted.

•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%

ef fect from refe rence to 60 Hertz).

Rectifie r-type meters employ a full-wave

rectifier and are available in ratings of

500µA to 30A.

Suppressed-ze ro DC Meters

DC meters can be mechanically suppressed

up to 20% of end-scale value. Howeve r,

additional errors are intro duced 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 calibrate d to ±1% of

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

with mirrored scale.

Conduit Mount ing 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-

mounte d case provides prote ction to the meter

under severe environmental conditions. The

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 fo r a specif ic value of lead re sistance other than

0.065 ohms is require d, contact factor y.
