Model 432.36+8xx, 432.56+8xx Diaphragm Pressure Gauge with Switch Contact

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, the model 432.56 or 432.36 switchGAUGE finds its use.

Switch contacts (electrical alarm contacts) make or break circuits dependent upon the pointer position of the indicating measuring instruments
Features
  • High overpressure safety, optionally up to 40, 100 or 400 bar, due to metallic diaphragm cushion, without liquidfilled measuring cell.
  • Wide choice of special materials.
  • Also available with liquid-filled case for high dynamic pressure loads or vibrations.
  • Gauges with inductive contacts for use in hazardous areas with ATEX approval.
  • Gauges with electronic contact for PLC applications.
