Cerabar PMC71B - pressure transmitter
Smart pressure transmitter which detects process anomalies like changes in the loop characteristics
This transmitter belongs to the new Cerabar generation. The device is robust and can be remotely controlled via app on a tablet using a secure Bluetooth connection. It allows condition based maintenance as well. The software is designed to simplify the handling. Intuitive wizards guide the user through setup, proof tests and verification of the device. Heartbeat Technology offers verification and monitoring functions to detect unwanted anomalies e.g. changes in loop characteristics.
Pressure measuring range: up to 40 bar (600 psi)
Fully vacuum resistant up to +150°C (302°F) process temperature
Accuracy: up to +/- 0.025%
Avantaje
With Heartbeat Technology you are able to verify the health of the device while the process is running.
Simple indication of device status - display changes from green to red when diagnostic messages occur
Reduce systematic failures - error free SIL commissioning and instrument guided proof testing
Wireless control of the device in hard to reach process areas with the SmartBlue App
Messer produces hydrogen in a steam reformer. The facility has a large number of protection and safety devices where pressure values play an important role.
The Egyptian government is working to replace liquid fuels with natural gas. To achieve this they targeted increasing the number of CNG stations in their country from 306 to 1000 by the end of 2021.
