Product Description

Product Description

High Stability
Experience unparalleled precision with the PDS Intelligent Transmitter, boasting a basic accuracy of an impressive 0.04%FS (and even reaching up to 0.025%FS). Remarkably, this transmitter maintains an astounding 99.9% accuracy even after a decade of continuous operation, significantly reducing maintenance expenses. Encased in a robust metal shell with fully sealed measurement components, it effortlessly withstands extreme chemical and mechanical stress. Coupled with superior electromagnetic interference resistance and a comprehensive lightning protection feature, the PDS Transmitter guarantees unmatched stability and reliability.
Intelligent Diagnosis
Equipped with a sophisticated integrated diagnosis function, the PDS Intelligent Transmitter vigilantly monitors both operational processes and its own status in real-time. Upon surpassing predefined event thresholds, it transitions to a fault alarm state, emitting an alarm current (3.6 or 22.8mA) to seamlessly integrate with system interlock or SIS security systems. During malfunctions, its LCD instantly displays 'Err', meticulously analyzing and indicating the malfunctioning components, thus simplifying maintenance, repair, and replacement procedures.
Activate the diagnosis feature using HART, FF, PA, and other protocol communications, where alerts manifest as warning or fault protection currents. It autonomously diagnoses SENSOR, ROM, RAM, EEPROM, and software health. Should the electronic unit or measurement element fail, the affected component can be conveniently replaced on-site without requiring re-calibration.
Simulation
Harness the power of simulation with the transmitter's advanced capabilities, which replicate process conditions to acquire measurement data and verify circuit connections and output status. The simulation output parameters include pressure, sensor temperature, and electronic temperature. Choose between fixed value simulation or linear function simulation modes. During simulation, the transmitter's output remains constant despite field pressure variations, reverting to its normal measurement state following key operations or a power cycle reset.
