Field of application

The Cerabar PMC51 digital pressure transmitter with capacitive, oil-free ceramic measuring cell is typically used in process and hygienic applications for pressure, level, volume or mass measurement in liquids and gases. It guarantees high degree of system safety thanks to vacuum-proof ceramic membrane with integrated breakage detection. Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2 according to IEC 61508 / IEC 61511.

Single chamber aluminum or stainless steel (316L) housing.

Process connections: Threads, flanges or hygienic connections
Process temperature: -40 to +130°C (-40 to +266°F), 150°C (302°F) for 1h
Measuring ranges: -1/0 up to +40bar (-15/0 to +600psi)
Accuracy: ±0.1%, "Platinum" ±0.075%
International explosion protection certificates, SIL, hygienic approvals, marine approvals

Benefits

Best fit for vacuum applications and applications with corrosive and abrasive media
Process safety through membrane breakage detection
Overload-resistant high purity ceramic sensor (99.9% Al₂O₃)
Condensation resistant also for hygienic applications
Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus
Process pressure up to SIL2, certified to IEC 61508 and IEC 61511
Available with mounted manifolds: always fit, always tested for leaks
