Field of application
The Cerabar PMP55 digital pressure transmitter with metal diaphragm seal is typically used in process and hygiene applications for pressure, level, volume or mass measurement in liquids. Suitable for high pressure as well as extreme process temperature applications from -70 up to +400°C (-94 to 750°F). Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2 according to IEC 61508 and IEC 61511.
Single chamber aluminum or stainless steel (316L) housing.
Process connections: Threads, flanges or hygienic connections
Process temperature: -70 to +400°C (-94 to +752°F)
Measuring ranges: -1/0 up to +400bar (-15/0 up to +6,000psi)
Accuracy: ±0.15%, "Platinum" ±0.075%
International explosion protection certificates, SIL, hygienic approvals, marine approvals
