Features

High Stability
The PDS Intelligent Transmitter, with its impressive basic accuracy of 0.04%FS, and achievable precision up to 0.025%FS, is a marvel in sustained reliability. Even after a decade of continuous operation, this device remarkably retains an accuracy of 99.9%, effectively minimizing maintenance expenses. Encased in a robust metal shell with fully sealed measurement components, it effortlessly withstands severe chemical and mechanical challenges. Furthermore, it boasts superior anti-electromagnetic interference capabilities and a robust lightning protection feature, all contributing to the unrivaled stability and reliability of the PDS Transmitter.

Intelligent Diagnosis
Equipped with advanced integrated diagnostics, the PDS Intelligent Transmitter vigilantly monitors its operational processes and internal status in real-time. Upon surpassing the set threshold of events, it transitions into a fault alarm state, emitting an alert current (3.6 or 22.8mA) crucial for system interlocking or SIS security system signaling. When a fault occurs, the LCD promptly flashes "Err", instantly analyzing and pinpointing defective components, streamlining the maintenance, repair, and replacement procedures for your convenience.
This diagnostic capability is further enhanced through HART, FF, PA, and other protocol communications, allowing alarms to manifest as warning signals or fault protection currents. It automatically scrutinizes SENSOR, ROM, RAM, EEPROM, and software health. In the event of electronic unit or measurement element failure, defective parts can be effortlessly replaced on-site without necessitating further adjustments.

Simulation
The PDS Transmitter's simulation function offers an innovative way to emulate process states for optimal measurement data acquisition. It is also instrumental in verifying circuit connections and output statuses. The simulation parameters encompass pressure, sensor temperature, and electronic temperature, while the output mode includes fixed value simulation or linear function simulation. Throughout the simulation, the output remains unaffected by field pressure, reverting to standard measurement operation following key activation or power-cycle restart.
