100mm 1.6 MPa Radial Direction Mounting All Stainless Steel
Electric Contact Pressure Gauge
Description
Stainless steel pressure gauge with inserted magnetic electrical
contact. It is usually used as a pressure switch to act on valves
or pumps when the pressure reaches the set point.
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
