Model 532.53+8xx Absolute 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 532.5x switchGAUGE finds its use.
Features
  • High overload safety, long service life due to metal media chamber sealing
  • Media chamber protected against unauthorised access
  • Also available with liquid-filled case for high dynamic pressure loads or vibrations
  • Instruments with inductive contacts for use in hazardous areas
  • Instruments with switch contact for PLC applications
