Endress+Hauser Cerabar PMC51

Absolute and gauge pressure

Pressure Sensor  Cerabar M PMC51 is a digital transmitter. Feature of this series – oil-free ceramic membrane for measurements in liquids and gases.

Such devices have found application in absolutely all industries. The presence of a ceramic membrane provides a fairly high level of device security. Cerabar M  Vacuum resistant, with built-in damage detection system. A dedicated menu enables simple start-up and commissioning, which saves time and costs significantly.

Benefits:

• Excellent for use in vacuum and for corrosive and abrasive service.
• High safety provided by diaphragm failure detection.
• Fracture-resistant ultra-pure ceramic diaphragm .
• High resistance to condensation. This feature is suitable for hygienic applications.
• Local display allows easy commissioning via menu, 4 … 20mA using FOUNDATION Fieldbus, HART, PROFIBUSPA protocols.
• Able to measure the pressure value in systems yes SIL2, certified according to IEC 61511 and IEC 61508.
• It has a modular concept for easy replacement of the electronic block or display.
• Types of process attachment – hygienic, flanged, threaded.
• Admissible temperature of the process itself – from -40°С - +130°С.
• Measuring range – from -1/0mbar to + 40bar.
• International certificates of explosion protection, SIL, WHG protection against overflow, hygienic certificates, marine certificates.
