Product Details

Oil Pressure Sensor Gauge Pressure Level Transmitter PMC71

Product Description

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.

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
Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus
Highest safety due to gastight feedthrough with capabilities up to SIL2/3, certified to IEC 61508
Cost savings with modular concept for easy replacement of sensor, display or electronics
