Features

High stability
Experience unparalleled precision with the PDS Intelligent Transmitter, boasting a remarkable basic accuracy of 0.04%FS, which can reach an impressive 0.025%FS. Even after a decade of continuous operation, it impeccably maintains 99.9% accuracy, drastically reducing maintenance expenses. Encased in a robust metal shell with fully sealed measurement components, it effortlessly withstands the harshest chemical and mechanical environments. Moreover, its superior anti-electromagnetic interference capability and lightning protection ensure unwavering stability and reliability, making the PDS Intelligent Transmitter your ultimate choice for high-stakes applications.

Intelligent diagnosis
Revolutionize your maintenance with the PDS Intelligent Transmitter's cutting-edge integrated diagnostic capabilities, providing real-time monitoring of both operational processes and internal system states. Upon detecting defined event thresholds, it proactively switches to a fault alarm mode, outputting an alert current (3.6 or 22.8mA) to establish a control signal for system interlocking or SIS security systems. During malfunction, the LCD instantly displays 'Err', automatically pinpointing and showcasing faulty components, vastly simplifying maintenance, repairs, and replacements.
Easily initiate the diagnostic functions via HART, FF, PA, and other protocol communications, with alarms signaled as warning or fault protection currents. It seamlessly performs automatic diagnostics on SENSOR, ROM, RAM, EEPROM, and software health. In the event of damage to the electronic unit or measurement element, faulty components can be effortlessly replaced on-site without the need for recalibration.

Simulation
The PDS Intelligent Transmitter's simulation function is a powerful tool, capable of emulating process states to deliver precise measurement data. It's invaluable for assessing transmitter circuit connections and output status. Available simulation output parameters include pressure, sensor temperature, and electronic temperature. Users can choose between fixed value simulations or linear function simulations. Notably, during simulation, the transmitter output remains unaffected by field pressure changes, seamlessly transitioning back to normal measurement status following key operations or a power cycle of the transmitter.
