This transmitter belongs to the new Deltabar generation. It is robust and easy to operate either locally or remotely. The transmitter can be controlled wireless via app on a mobile device using a secure Bluetooth connection. The PMD55B allows condition-based maintenance which increases efficiency in technical service significantly. The software is designed to simplify the handling. Intuitive wizards guide you through the setup and proof testing of the device which minimizes operating errors.
Pressure measuring range: up to 40 bar (600 psi)
Static pressure up to 250bar (3750psi)
Accuracy: up to +/-0.055%
Benefits
Wireless control of the device in the process area with the SmartBlue App without interrupting the process
Reduce on site accidents and protect equipment when instruments are in difficult to reach areas
Reduce systematic failures - error free SIL commissioning and instrument guided proof testing
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.
