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
