Considerations in Selecting a Pressure Gauge

4

RANGEThe maximum operating pressure should not exceed 75% of the full-scale range. The normal operating range should be in the middle half of the range (between 25% and 75% of thefull-scale range); whenever possible.

DIAL SIZESelect a dial size that allows you to comfortably read the dial from the normal distance when installed.

PRESSURE SYSTEM MATERIALThe media to which the gauge will be subjected is critical to the selection of the proper material for the bourdon tube, bellows, and socket. Consult “corrosion chart” on Page 5 forproper selection of pressure system materials. Weksler offers various models with:

Phosphor bronze bourdons (or bellows) with brass sockets.316 stainless steel bourdons (or bellows) with 316 stainless steel sockets.316 stainless steel bourdons with alloy steel sockets.Monel bourdons with monel sockets..

For applications where the above materials may not be suitable, a diaphragm seal will be necessary to protect the pressure gauge system.

ACCURACYSelect a gauge having the desired accuracy as follows:

1⁄4% – test gauges only (not for in-line service)1⁄2% – Weksler “Royal” gauges (41⁄2˝ dial size and larger)1% – Weksler “Regal” gauges, 31⁄2 “Royal Gauges, 100 MM Gauge, “EA14” gauge2-1-2% – Weksler Duplex, Differential and Low Pressure Gauges3-2-3% – Weksler BY12, BY42, BK72, UA15, UA20, UA25, UA35 series utility gauges

MOVEMENTSelect either a gauge with 300 series stainless steel movement for long wear (Weksler “Royal” gauges, 100 mm gauges, and BY42 series gauges); or a gauge with bronze or brassmovement for applications where vibration and pulsation are not present (all other Weksler gauges).

CASEA wide variety of case styles and materials are offered. Determine how the gauge is to be mounted: direct, surface (wall) or flush (in panel). Determine the desired case materials:polyproylene (or phenol); aluminum (black enameled) or stainless steel (300 series).

Determine case type: Safety (solid front with blow-out back)

Standard (open front with rubber blow-out disc at rear)Note – All safety case styles are designated by a number.

Standard case styles are designated by a letter.

WINDOWA glass face is standard in most gauges. If breakage is a concern, a plastic or shatterproof glass face is optional at extra cost on most Weksler “Royal” and “Regal” gauges. (Glycerinefilled and sanitary gauges have plastic face as standard).

POINTERAll Weksler gauges (except utility types) have adjustable pointers. This permits pointer repositioning during calibration check or allows maximum precision at a specific point.

TEMPERATUREThe ambient temperature to which the gauge will be subjected should not exceed 150°F. If higher temperatures are encountered the gauge must be isolated from the source of heat.The temperature of the media to which the gauge is subjected to is also critical. Gauges with phosphor bronze bourdons should not be subjected to process temperatures in excess of150°F. Gauges with metal cases and either 316 stainless steel or monel bourdons can withstand higher process temperatures, but as temperature exceeds 150°F hardening of thegasketing and discoloration of the dial may occur. In addition, accuracy will be affected by approximately 1.5% per 100°F. Both 316 stainless steel and monel gauges in metal caseswill withstand 750°F for short periods of time without rupture, but other parts of the gauge will be destroyed and calibration will be lost.

VIBRATIONIf present, a glycerine filled gauge is recommended.

PULSATIONIf present, a pressure snubber or throttle screw is recommended.

WARNING: Misuse, Including Excessive Pressure, Vibration, Pulsation, Temperature And CorrosionMay Cause Failure That Can Result in Damage Or Injury.We suggest that users of Pressure Gauges refer to American National Standard ASME B40.1 entitled“Gauges, Pressure And Vacuum Indicating Dial Type – Elastic Element” for guidance in Gaugeselection. This document may be obtained from American Society of Mechanical Engineers (ASME)United Engineering Center, 345 East 47th Street, New York, N.Y. 10017.

Corrosion Chart

The media being measured must be compatible withthe wetted parts of the pressure instrument. To usethe chart below, locate the media whose pressure isto be measured and select a suitable material fromthose available.

This is a simplified chart and assumes the mediatemperature is below 200°F except for media withan* which must be below 100°F. Throttling devicesand/or a liquid filled instrument are recommendedin applications with pulsation or vibration. These

recommendations are only a guide, as service life isdependent on temperature, concentrations, catalyststhat may be added, or other conditions beyond ourcontrol. Consult customer service for specificapplications and for any media not listed.

NOTE: The accuracy of measurement is influenced by the ambienttemperature. The Weksler Test Gauge is calibrated to be accurate towithin 1⁄4 of 1% of full scale range at 77°F. (25°C). Using the gauge inambient temperatures other than this requires the application of acorrection of 0.02% of the indicated pressure for each 1°F. Thecorrection is minus if the temperature is higher and plus if lower than 77°F.

Test Gauges are designed specifically for periodic bench testing and recalibration ofproduction type gauges. They are also recommended for use in test cells such as onresearch projects, and as portable instruments for field inspectors and traveling engineers.Test gauges are not suggested for continuous duty in service installations.

Movement: Precision design, stainless steel rotary gear type. Wear-resistant, andvirtually frictionless for long, accurate service.

Dial &Pointer: Mirrored dial and balanced knife-edge aluminum pointer permits reading

without parallax error. Dial surface is white, with black numerals andgraduations in a full 270° arc. Graduation lines are same width as theknife edge on pointer.

ConnectionLocation: 1/4 or 1/2 male NPT

Case: Choice of two black enameled die cast aluminum cases, solid front, safetytype

Style 4: Back flanged type, bayonet ring, for surface or direct mounting.Bottom connected.
