Description

Application

The Deltabar PMD78B is part of the latest generation of differential pressure transmitters, designed for robustness and remote control via the SmartBlue App using a secure Bluetooth® connection. It supports condition-based maintenance, enhancing plant uptime. The device’s software is user-friendly, featuring intuitive wizards that assist with setup, proof tests, and device verification. Additionally, Heartbeat Technology enables continuous monitoring and verification, detecting issues such as plugged impulse lines.

  • Pressure measurement range: 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 operation in hard-to-reach areas through the SmartBlue App and Bluetooth® connectivity.
  • Minimize systematic errors with error-free SIL commissioning and guided proof testing.
  • Heartbeat Technology allows real-time verification of device health, improving plant availability.
  • Simplified device status monitoring: the display switches from green to red when diagnostic messages appear.
