Product Overview
The Deltabar PMD75B represents the next generation of industrial process control, engineered to eliminate unplanned downtime and simplify field operations. As a premium smart differential pressure transmitter, the PMD75B goes beyond basic pressure measurement by offering real-time, condition-based monitoring. Equipped with proprietary Heartbeat Technology, it actively detects process anomalies—such as plugged impulse lines—before they cause costly system shutdowns.
Whether you are managing complex flow, level, or differential pressure applications, the Deltabar PMD75B delivers up to 0.035% Platinum accuracy and seamless wireless configuration via the SmartBlue App, making it the most reliable asset for demanding B2B industrial environments.
Key Benefits for Industrial Operations
- Predictive Maintenance with Heartbeat Technology: Verify instrument health and detect plugged impulse lines in real-time without interrupting active processes.
- Visual Status Alerts: High-visibility LED display changes from green to red instantly when diagnostic or safety messages occur.
- Error-Free Safety Commissioning: Instrument-guided wizards simplify SIL commissioning, proof testing, and device verification to mitigate human error.
- Secure Wireless Control: Safely configure, monitor, and troubleshoot hard-to-reach measurement points from up to 25 meters away via the SmartBlue Bluetooth® App.
- Extreme Process Resilience: Built for high-pressure environments with a static pressure capability up to 420 bar (6300 psi) and an overpressure limit up to 630 bar.
