Features

Impeccable Stability
The PDS intelligent transmitter stands as a beacon of precision, with a basic accuracy of 0.04%FS, reaching heights of up to 0.025%FS. Even after a decade of relentless use, it remarkably retains 99.9% accuracy, significantly cutting down on maintenance expenses. Encased in a robust metal shell with completely sealed measurement components, this transmitter confidently withstands extreme chemical and mechanical stresses. Its powerful anti-electromagnetic interference capabilities, coupled with lightning protection, promise unwavering stability and reliability, ensuring the PDS transmitter is an industry leader in performance.

Advanced Intelligent Diagnosis
Equipped with a sophisticated integrated diagnosis function, the PDS intelligent transmitter vigilantly monitors operational processes and its own condition in real-time. Upon surpassing a predefined number of events, it transitions into a fault alarm state, outputting an alarm current (3.6 or 22.8mA) to cue the system interlocking or SIS security system. During malfunction, the LCD screen prominently displays 'Err' and swiftly identifies and indicates faulty components, streamlining maintenance, repair, and replacement processes for unparalleled ease and efficiency.
This diagnostic ability can also be activated through communication protocols such as HART, FF, and PA. Alarms manifest as either warning or fault protection currents, while automatic diagnostics extend to SENSOR, ROM, RAM, EEPROM, and software health checks. In the event of damage to the electronic unit or measurement elements, the defective component can be seamlessly swapped on-site, eliminating the need for readjustments.

Comprehensive Simulation Capabilities
The PDS transmitter's simulation function is a powerful tool, capable of mimicking process states to acquire measurement data. It also serves to verify the transmitter circuit's connection and output status. Simulation output parameters span pressure, sensor temperature, and electronic temperature. Offering versatility, the simulation output mode includes either fixed value simulation or linear function simulation. Throughout the simulation, the transmitter's output remains unaffected by field pressure, automatically returning to the standard measurement state following a key operation or power cycle restart, ensuring seamless operational continuity.
