Absolute And Gauge Pressure Cerabar – PMP21

Field of application

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.

Pressure transducer with piezo-resistive metal sensor to measure absolute or gauge pressure in gases or liquids.

  • Process connections: Threads

  • Process temperature: -40 to +100°C (-40 to +212°F)

  • Process pressure: 400mbar to +400bar (6 to 6,000psi)

  • Accuracy: ±0.3% of span

  • International explosion protection certificates, marine approvals

Benefits

  • Easy and time-saving installation and set up within the plant due to very compact construction and customizable measuring ranges

  • High reference accuracy of 0.3% together with high long- term stability and repeatability ensures a high quality of process monitoring

  • Enhanced process availability is underpinned by the stringent use of 316L material and the possibility of a submersible version with IP68 ingress protection rating

  • The need for documentation and traceability as well as safety in the plant can be supported by PMP21 as it ensures the compliance to various hazardous area and marine certifications and features optional EN10204 3.1 material certificates
