Martel Electronics BetaGauge 3II - Manual (Page 33)

Input Modules 2-6
CAUTION: Failure to use a backup wrench may
damage the calibrator and/or the module
and will void the product warranty.
Do not use the pressure connections to
support the calibrator.
Pressure Module Media Compatibility
BetaPort–P pressure modules consist of two basic
types:
 non-isolated
 isolated
Consult the calibrator specifications (Appendix B) for
details about which modules are isolated and which are
non-isolated.
Modules with isolated sensors have an isolating
diaphragm made of 316 stainless steel and may be used
with any media compatible with 316 S.S., and are
available for most pressure ranges.
CAUTION: Modules with non-isolated sensors may
be used only in the presence of non-
corrosive media such as clean, dry, non-
corrosive air or gases. Certain acids may
react with stainless steel and should not
be introduced into the sensor. Consult
with the media or substance manufacturer
for further information.
NOTE: The ranges and the resolution of the various
pressure modules are described in Appendix
B, Specifications.
