100mm -0.8 bar Vacuum Radial Direction Mounting All Stainless Steel Electric Contact Pressure Gauge
Description
In industrial processes, there are times when you need to read the pressure values and at the same time have the ability to alter electric circuits (open/close) at desired set values. In case the media demands a stainless steel instrument, then InstruMate model M12 electric contact pressure gauges are the right choice. Contact-Mate M12 is a heavy duty pressure gauge with switch contacts of snap-action type.
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
