Model 532.53+8xx Absolute Pressure Gauge with Switch Contact
Brand: WIKA Instruments Ltd.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
