Electric Contact pressure gauge

Stewart Buchanan electric contact pressure gauges are suitable for many applications in industrial and process instrumentation – the pressure elements are available in copper alloy, stainless steel or special materials.

Unless advised differently all Stewart Buchanan pressure gauges are calibrated in accordance with EN837-1 to an accuracy of Class-1.

Electric contact pressure gauges are available to meet all applications and a high standard of quality ensures many years of trouble free operation.


Technical Specification

Temperature  -20 to + 140 Deg.c. (Maximum of 80 Deg.c. for inductive and pneumatic types)
ContactsSingle or double contacts are standard with triple contacts available on special request
Standard Contact Device (Low Action)Contacts are intended for use where a heavy contact load is not required and the instrument is not subject to vibration
Magnetic Contact DeviceContacts can be used in any non-hazardous area and are largely insensitive to vibration
Inductive Contact Device (Intrinsically Safe Ex)Suitable for use in hazardous areas with explosion hazard rating up to (Ex) i G5
Pneumatic Contact Device Units serve as monitoring and regulating units in pneumatic systems and can be used in hazardous areas to the highest Ex-safety classification (Zone 0).
