Features

Outstanding Stability
The PDS intelligent transmitter boasts a remarkable baseline accuracy of 0.04%FS, with potential refinement to an impressive 0.025%FS. Even after a decade of uninterrupted service, it maintains a staggering 99.9% accuracy, dramatically cutting down on maintenance expenditures. Constructed with a robust metal shell and entirely sealed measurement components, it effortlessly withstands severe chemical and mechanical stresses, while offering superior resilience against electromagnetic interference and lightning. This ensures the PDS transmitter remains a paragon of high stability and dependability in any challenging environment.

Cutting-edge Diagnosis
Equipped with an integrated, real-time diagnostic function, the PDS intelligent transmitter keeps a vigilant watch over its operational processes and internal status. Should the frequency of predefined events escalate, the transmitter enters a fault alert mode, discharging an alarm current (3.6 or 22.8mA) to trigger a control signal for system interlocks or SIS safety frameworks. During such failures, an 'Err' message is displayed on the LCD, pinpointing faulty components for effortless maintenance, repair, or replacement.
Through HART, FF, PA, and other communication protocols, the diagnostic function can also be initiated to signify alarms as warnings or fault protection currents. It automatically scrutinizes SENSOR, ROM, RAM, EEPROM, and software integrity. If the electronic unit or measurement element is compromised, the defective segment can be swiftly replaced on-site, negating the need for recalibration.

Advanced Simulation
The transmitter's simulation feature emulates process conditions to derive measurement data, ideal for verifying circuit connectivity and transmitter output status. Simulation output parameters encompass pressure, sensor temperature, and electronic temperature, available in fixed value or linear function modes. During simulation, the transmitter's output remains unaffected by actual field pressure, reverting to standard measurement post-key operation or power cycle.
