If a ceramic sensor is required, please use the PMC51.
The Cerabar PMP51 digital pressure transmitter uses a metal diaphragm and is mainly used for the pressure, level, volume and mass measurement of liquids or gases in the process industry and the hygiene sector. The PMP51 is designed for high-pressure measurement applications with a maximum working pressure of up to 400bar. The measuring range is adjustable and the quick setup function saves cost and time. It complies with IEC 61508 and IEC 61511 and meets SIL2 functional safety requirements.
Advantages
Precise measurement even under changing process temperature conditions
Excellent repeatability and long-term stability
Process pressure monitoring suitable for SIL2, certified to IEC 61508 and IEC 61511
Modular design for measuring differential pressure, static pressure and pressure (Deltabar M - Deltapilot M - Cerabar M), e.g. replaceable display module and main electronics module
Simple and safe menu-guided operation: via the on-site display module, or remotely via 4-20 mA HART, PROFIBUS PA, FOUNDATION Fieldbus
Optional manifold: also pressure-tested
Areas of application
Single-compartment aluminum or stainless steel (316L) housing
Process connection: thread, flange or hygienic connection
