The Ceraphant PTC31B is a cost-effective pressure switch with a ceramic diaphragm sensor. The sensor is vacuum-resistant and can safely measure and monitor absolute and gauge pressure. The pressure switch has a compact design and high stability, withstands high vacuum and can withstand an absolute vacuum down to 0 bar.
Advantages
Built-in electronic switch component enables decentralized and economical monitoring
Convenient function check and on-site information display via LED indicator and digital display
The capacitive, non-oil-filled ceramic diaphragm sensor (Ceraphire) has a minimum range of 0...20 mbar for stable process monitoring
High process availability, suitable for vacuum applications and measurement of abrasive media
Areas of application
Pressure switch with ceramic diaphragm sensor for absolute and gauge pressure monitoring in gases, steam, liquids and dust.
