Ceraphant PTP31B - Absolute and gauge pressure ©Endress+Hauser

Pressure measuring principle

Cost-effective pressure switch with welded metal sensor for measurement in gases, steams or liquids

The Ceraphant PTP31B is a price-attractive pressure switch with piezoresistive sensor for safe measurement and monitoring of absolute and gauge pressure. The pressure switch with compact design is extremely stable and overload resistant for up to +400 bar. The IO-Link capability allows easy integration and parametrization of the device.
