Pressure measuring principle

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

The Cerabar PMP21 is a price-attractive and very compact pressure transmitter. It features a piezo-resistive sensor and is able to measure absolute or gauge pressure from 400mbar up to 400bar. The PMP21 is designed to withstand the harsh conditions in the process industry with ingress protection grades up to IP 68 and high quality materials like 316L. It can be used in most areas as it offers various certifications like hazardous area or marine certificates.
