The Cerabar PMP21 is a highly cost-effective ultra-compact pressure transmitter. It uses a piezoresistive sensor with an absolute or gauge pressure measuring range of 400 mbar..100 bar. The PMP21 can measure under demanding conditions in the process industry, with a maximum degree of protection of IP68 and high-quality materials (e.g. 316L). Numerous approvals (e.g. explosion protection approval or marine approval) make it suitable for most measuring applications.
Advantages
Ultra-compact design and user-configurable measuring range allow simple, time-saving instrument installation and setup in the plant
Reference measuring accuracy of 0.3% with high long-term stability and high repeatability, ensuring high-quality process monitoring
Made entirely of 316L for improved process compatibility; versions with IP68 degree of protection can be used submerged in water
The PMP21 has numerous explosion protection and marine approvals, and an EN10204 3.1 material certificate is also available to meet documentation, traceability and device safety requirements
