Pressure Gauge Selection
Considerations in Selecting
a Pressure Gauge
4
RANGE
The 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 the full-
scale range); whenever possible.
DIAL SIZE
Select a dial size that allows you to comfortably
read the dial from the normal distance when
installed.
PRESSURE SYSTEM MATERIAL
The media to which the gauge will be subjected
is critical to the selection of the proper material
for the Bourdon tube, bellows, and socket.
Weksler models are offered with:
Phosphor bronze Bourdon tube (or bellows)
with brass sockets.
316 stainless steel Bourdon tube (or
bellows) with 316 stainless steel sockets.
316 stainless steel Bourdon tube with alloy
steel sockets.
Monel Bourdon tubes 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.
ACCURACY
Select a gauge with the desired accuracy as
follows:
1
/4% – test gauges only (not for in-line
service)
1
/2% – Weksler Royal gauges (4
1
/2˝ dial
size and larger) and Weksler digital
gauges (2
1
/2˝ case size)
1% – Weksler Regal gauges, 100 MM
Gauge, EA14 gauge
2-1-2% – Weksler duplex, differential and low
pressure gauges
3-2-3% – Weksler BY12, BY42, UA15, UA20,
UA25, UA35 series utility gauges
MOVEMENT
Select either a gauge with 300 series stainless
steel movement for long wear or a gauge with
bronze or brass movement for applications
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).
WARNING: Misuse, Including Excessive
Pressure, Vibration, Pulsation, Tempera-
ture And Corrosion May 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
Gauge selection. This document may
be obtained from American Society of
Mechanical Engineers (ASME) United
Engineering Center, 345 East 47th Street,
New York, N.Y. 10017.
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.
WINDOW
A 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. (Glycerin
filled and sanitary gauges have plastic face as
standard).
POINTER
All Weksler gauges (except utility types) have
adjustable pointers. This permits pointer repo-
sitioning during calibration check or allows
maximum precision at a specific point.
TEMPERATURE
The 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 Bourdon tubes should not be
subjected to process temperatures in excess
of 150°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
the gasketing 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 cases
will withstand 750°F for short periods of time
without rupture, but other parts of the gauge
will be destroyed and calibration will be lost.
VIBRATION
If present, a glycerin filled gauge is
recommended.
PULSATION
If present, a pressure snubber or throttle screw
is recommended.

RANGE
The 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 the full-
scale range); whenever possible.
DIAL SIZE
Select a dial size that allows you to comfortably
read the dial from the normal distance when
installed.
ACCURACY
All Weksler BiMetal Thermometers have an
accuracy of ± 1% of the full-scale range. For
accurate readings stem must be immersed at
least 2 inches in liquids and 4 inches in gases.
UNDER/OVER RANGE PROTECTION
Temporary exposure to temperatures under or
over 50% of the full-scale range will not impair
accuracy (up to 500°F or 260°C maximum).
CASE ASSEMBLY
The case, bezel, stem and fittings are stainless
steel (300 series). The head assembly is sealed
to exclude dirt, dust and moisture on 3˝ and 5˝
dial sizes, all joints are welded.
DIALS
Dials are white with clear black graduations
and numerals and are easy to read.
FACE
A gasketed glass window is standard on 3˝ and
5˝ dial sizes. Where breakage is a concern, a
plastic or shatterproof glass window is optional
at extra cost. On 1˝ and 2˝ dial sizes a plastic
window is standard (no options available).
Plastic windows are not suitable where head
temperature exceeds 150°F (65°C).
EXTERNAL ADJUSTMENT
An external adjustment at the rear of the 3˝ and
5˝ case permits adjustment at a specific point
or pointer repositioning during calibration
check.
VIBRATION AND SHOCK
If present, use of either a heavy duty bimetal or
a remote mounted gas actuated thermometer
is recommended.
HIGH PRESSURE OR CORROSIVE APPLICATIONS
In these applications, use of a separable ther-
mowell is recommended. In addition to pro-
tecting the thermometer, thermowells facilitate
removal of the thermometer without having to
shut down the system.

Gas Actuated Thermometers –
Selection Terms
RANGE
The maximum operating temperature should
not exceed 75% of the full-scale range. The
normal operating range should be in the mid-
dle half of the range (between 25% and 75% of
the full-scale range); whenever possible.
ACCURACY
All Weksler gas actuated dial thermometers
have an accuracy of ± 1% of the full-scale
range. For accurate readings the entire sensi-
tive portion of the bulb must be fully immersed
into the medium being measured.
CASE
A wide variety of case styles and materials are
offered. Determine how the thermometer is to
be mounted: direct, surface (wall) or flush (in
panel). Determine the desired case material:
polypropylene, aluminum (black enameled) or
stainless steel (300 series).
FACE
A gasketed glass window is standard. Where
breakage is a concern, a plastic or shatterproof
glass window is optional at extra cost. Plastic
windows are not suitable where head tempera-
ture exceeds 150°F (65°C).
POINTER
All Weksler gas actuated thermometers have
adjustable pointers. This permits pointer repo-
sitioning during calibration check or allows
maximum precision at a selected point within
the scale range.
MOUNTING
Weksler gas actuated thermometers are avail-
able in remote mounted types (with capillary
tubing between case and sensing bulb) and
direct mounted types (sensing bulb is attached
directly to case). Remote mounted types allow
the temperature to be read at a location remote
from the actual temperature source. Remote
mounting is also desirable to isolate the head
(case, scale, pointer and internal parts) from
the damaging effects of shock, vibration or
excessive heat that may be present at the tem-
perature source. Direct mounted thermometers
are available in “adjust angle” types which
allow the head of the thermometer to be posi-
tioned for the most desirable viewing angle.
Direct mounted units are installed directly on
pipes, tanks or other vessels.
BULB TYPES
Weksler gas actuated thermometers are avail-
able with various styles of plain bulbs or union
connection bulbs. The bulb is the sensing ele-
ment at the tip of the thermometer that reacts
to temperature changes. The entire thermome-
ter including the bulb, head assembly and cap-
illary tubing (on remote types) is filled with an
inert nitrogen gas offering fast response and
linear dial graduations. Plain bulbs are those
without threaded fittings for sensing air tem-
perature or liquid temperatures in open tanks,
vats, sinks, etc. Union connected bulbs have
threaded swivel nuts that hold the bulb into a
bulb fitting such as a thermowell, bushing or
flange.
HIGH PRESSURE OR CORROSIVE
APPLICATIONS
In these applications, use of a separable ther-
mowell is recommended. In addition to pro-
tecting the thermometer, thermowells facilitate
removal of the thermometer without having to
shut down the system.
