Considerations in Selecting a Pressure Gauge RANGE Safety The maximum operating Pressure should not (solid front with blow-out back) warning: Misuse, Including Excessive exceed 75% of the full -scale range.

We suggest that users of Pressure Note A. ll safety case styles are designated Gauges refer to American National DIAL SIZE by a number. Standard case styles are Standard ASME entitled Gauges, designated by a letter.

5 Select a dial size that allows you to comfortably Pressure And Vacuum Indicating Dial read the dial from the normal distance when WINDOW Type Elastic Element for guidance in installed. A glass face is standard in most gauges. If Gauge selection. This document may breakage is a concern, a plastic or shatterproof be obtained from American Society of Pressure SYSTEM MATERIAL Mechanical Engineers (ASME) United glass face is optional at extra cost on most The media to which the gauge will be subjected Weksler Royal and Regal gauges.

6 (Glycerin Engineering Center, 345 East 47th Street, is critical to the selection of the proper material filled and sanitary gauges have plastic face as New York, 10017. for the Bourdon tube, bellows, and socket. standard). Consult corrosion chart on page 5 for proper selection of Pressure system materials. POINTER. Weksler models are offered with: All Weksler gauges (except utility types) have Phosphor bronze Bourdon tube (or bellows). Pressure Gauge Selection adjustable pointers. This permits pointer repo- with brass sockets.

7 Sitioning during calibration check or allows 316 stainless steel Bourdon tube (or maximum precision at a specific point. bellows) with 316 stainless steel sockets. 316 stainless steel Bourdon tube with alloy Temperature . steel sockets. The ambient Temperature to which the gauge Monel Bourdon tubes with Monel sockets. will be subjected should not exceed 150 F. If higher temperatures are encountered the gauge For applications where the above materials must be isolated from the source of heat. The may not be suitable, a diaphragm seal will Temperature of the media to which the gauge be necessary to protect the Pressure gauge is subjected to is also critical.

8 Gauges with system. phosphor bronze Bourdon tubes should not be ACCURACY subjected to process temperatures in excess Select a gauge with the desired accuracy as of 150 F. Gauges with metal cases and either follows: 316 stainless steel or monel bourdons can 1. /4% test gauges only (not for in- line withstand higher process temperatures , but service) as Temperature exceeds 150 F hardening of 1. /2% Weksler Royal gauges (41/2 dial the gasketing and discoloration of the dial may size and larger) and Weksler digital occur.

9 In addition, accuracy will be affected gauges (21/2 case size) by approximately per 100 F. Both 316. 1% Weksler Regal gauges, 100 MM stainless steel and monel gauges in metal cases Gauge, EA14 gauge will withstand 750 F for short periods of time 2-1-2% Weksler duplex, differential and low without rupture, but other parts of the gauge Pressure gauges will be destroyed and calibration will be lost. 3-2-3% Weksler BY12, BY42, UA15, UA20, VIBRATION. UA25, UA35 series utility gauges If present, a glycerin filled gauge is MOVEMENT recommended.

10 Select either a gauge with 300 series stainless PULSATION. steel movement for long wear or a gauge with If present, a Pressure snubber or throttle screw bronze or brass movement for applications is recommended. where vibration and pulsation are not present. CASE. A 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).
