Field of application

The Deltabar PMD55 belongs to a new generation of transmitters. It is robust and easy to operate, either locally or remotely. The transmitter can be controlled wirelessly via a mobile app using a secure Bluetooth connection. The PMD55B allows condition-based maintenance, which significantly increases efficiency in technical service.

The software is designed to simplify handling, with intuitive wizards that guide users through setup and proof testing, minimizing 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
