Pressure measuring principle

Cost-effective pressure transducer with ceramic sensor for measurement in gases or liquids

The Cerabar PMC21 is a very compact pressure transmitter. It features a capacitive, oil-free ceramic sensor and is able to measure absolute or gauge pressure from 100mbar up to 40bar. It is designed to withstand the harsh conditions in the process industry with ingress protection grades up to IP68 and highly abrasion resistant Ceraphire membrane as well as high quality 316L housing. It can be used in most areas as it offers various certifications like hazardous area or marine certificates.
