Field of application
The Cerabar PMC71 digital pressure transmitter with capacitive, oil-free ceramic measuring cell is typically used in the 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. SIL2/3 according to IEC 61508.
Two chamber aluminum or stainless steel (316L) housing.
Process connections: Threads, flanges or hygienic connections
Process temperature: -40 to +150°C (-40 to +302°F)
Measuring ranges: -1/0 up to to +40bar (+1.5 to +600psi)
Accuracy: ±0.05%, "Platinum" ±0.025%
International explosion protection certificates, overfill prevention WHG, 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)
HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
