Absolute and gauge pressure
Ceraphant PTC31B

Pressure measuring principle

Cost-effective pressure switch with oil-free ceramic sensor for measurement in gases or liquids

The Ceraphant PTC31B is a price-attractive pressure switch with ceramic, vacuum tight measuring cell for safe measurement and monitoring of absolute and gauge pressure. The pressure switch with compact design is extremely stable and high vacuum resistant up to 0bar abs. The IO-Link capability allows easy integration and parametrization of the device.
