Cerabar PMP51B – pressure transmitter

    Smart pressure transmitter with metal membrane for highly accurate measurement of liquids and gases

    Field of application

    This transmitter belongs to the new Cerabar generation. It combines robustness with numerous benefits: e.g easiest local or remote operation and condition-based maintenance which promotes better management of scheduled plant shutdowns.
    The software is designed to simplify the handling. Intuitive and clear wizards guide you through the commissioning and proof testing of the device. The transmitter can be remotely controlled via app on a mobile device and a secure Bluetooth connection.

    • Pressure measuring range: up to 400 bar (6000 psi)

    • Process temperatures up to 400°C (752 °F) with diaphragm seal

    • Accuracy: up to +/- 0.055%

    Benefits

    • Reduce systematic failures – error free SIL commissioning and instrument guided proof testing

    • Reduce on site accidents and protect equipment when instruments are in difficult to reach areas

    • Wireless control of the device in the process area with the SmartBlue App without process interruption
