Deltabar PMD78B – differential pressure transmitter

This transmitter belongs to the new Deltabar generation. The device is robust and can be remotely controlled via SmartBlue App using a secure Bluetooth connection. It allows condition based maintenance to increase plant availability. 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. plugged impulse lines.

Specialist with one or two capillaries for accurate differential pressure measurement. Intuitive and clear wizards for commissioning, proof tests and verification.

  • Pressure measuring ranges up to 40 bar (600 psi)
  • Process temperatures up to 400 °C (752 °F) with diaphragm seal
  • Static pressure: up to 160 bar (2400 psi)
  • Accuracy: up to +/- 0.075%

Benefits

  • Wireless control of the device in hard to reach areas with the SmartBlue App and a Bluetooth® connection
  • Reduce systematic failures – error free SIL commissioning and instrument guided proof testing
  • With Heartbeat Technology you are able to verify the health of the device while the process is running. This increases plant availability.
  • Simple indication of device statusdisplay changes from green to red when diagnostic messages occur
