NPT Plastic Electric Contact Pressure Gauges Flange 400 Bar Manometer
100mm Chrome Plated Steel 400 bar Manometer Brass Connection Electric Contact Pressure Gauge with Flange
Description
Having more windings also increases the total volume of the Bourdon tube. This internal volume acts as a buffer for fluctuations in the process pressure. In this way, fluctuations are better absorbed, and the pointer will remain stable.
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
