100mm 40 MPa Lower Back Connection Flange Panel Mount All Stainless
Steel Electric Contact Pressure Gauge
Description
Electric contact pressure gauges are suggested where application is
for control of pressure & for Audible or visible alarms.
Electrical gauges give electrical output which can be used to turn
a motor on/off & similar applications. Single or double contacts
are standard with triple contacts available on special request.
Make or break settings can be achieved in a variety of permutations
with rising or falling pressure / temperatures.
Applications
Control and regulation of industrial processes
Monitoring of plants and switching of circuits
For gaseous and liquid media that are not highly viscous or
crystallising and will not attack copper alloy parts
Special features
High reliability and long service life
Up to 4 switch contacts per instrument
Instruments with electronic contacts for PLC applications
Contact gauges comply with DIN 16085
