purposes.
TEMPERATURE LIMITS
Ambient Process Storage
Dry
Note: Other than discoloration of the dial and hardening of the
gasketing that may occur as ambient or process temperatures
xceeds 150°F, non-liquid-filled gauges with standard glass
e
windows, can withstand continuous operating temperatures up
o 250°F (121°C). Accuracy at temperatures above or below the
t
reference ambient temperature of 68°F (20°C) will be affected by
pproximately .4% per 25°F. Gauges with silver brazed joints will
a
withstand 450°F (232°C). Ranges less than 100 psi have soft
oldered joints and can withstand 250°F (121°C) for short times
s
without rupture, although other parts of the gauge will be
destroyed and calibration will be lost. For continuous use and for
process or ambient temperatures above 250°F (121°C), a
diaphragm seal or capillary or siphon is recommended.
