Description

Application

The Deltabar PMD75B, part of the latest Deltabar series, is a highly durable differential pressure transmitter that can be operated remotely through the SmartBlue App, using a secure Bluetooth connection. This feature enables condition-based maintenance, optimizing plant uptime and reliability. The intuitive software simplifies operation, providing step-by-step wizards for easy setup, proof testing, and device verification. Additionally, Heartbeat Technology ensures ongoing device verification and monitoring, helping to detect issues like plugged impulse lines early on.

The device supports pressure measurement ranges up to 250 bar (3750 psi) for gauge/absolute and 40 bar (600 psi) for differential pressure, with a maximum static pressure of 420 bar (6300 psi). Its accuracy is rated at up to ± 0.035%.

 

Benefits

With integrated Heartbeat Technology, the health of the device can be verified during operation, leading to improved plant availability.

The status of the device is easy to interpret, as the display changes from green to red in the event of diagnostic alerts.

Systematic failures are minimized through error-free SIL commissioning and guided proof testing.

Wireless control is possible in hard-to-access locations, facilitated by the SmartBlue App.
