Product Description

Product Description

Introducing the PDS803 pressure transmitter, the epitome of precision in pressure measurement for liquids, gases, or steam. This advanced device seamlessly converts pressure into a reliable 4-20mA direct current output, ingeniously enhanced with integrated HART communication. Additionally, it supports PROFIBUS-PA and FF communication signals, ensuring versatile connectivity. Experience effortless control and oversight with its capability for remote configuration and monitoring via modern communication devices, making it an indispensable tool for high-tech operations.

Features

High Stability

The PDS Intelligent Transmitter showcases an impressive basic accuracy of 0.04%FS, reaching a remarkable precision of up to 0.025%FS. Even after a rigorous decade of continuous operation, it astonishingly retains 99.9% accuracy, ensuring significant reductions in maintenance expenses. Encased in a robust metal shell with fully sealed measurement components, this transmitter confidently withstands extreme chemical and mechanical stresses. Moreover, it excels with potent anti-electromagnetic interference capabilities and a robust lightning protection feature, guaranteeing unmatched stability and reliability that users can count on.

Intelligent Diagnosis
The PDS Intelligent Transmitter is equipped with an advanced integrated diagnostic function that vigilantly monitors both operational processes and its own status in real time. Should it exceed a predetermined event threshold, the transmitter promptly switches to a fault alarm mode, outputting an alert current of either 3.6 or 22.8mA. This provides a vital control signal for system interlocks or SIS security systems. During such failures, the LCD automatically displays an 'Err' message, swiftly analyzing and identifying the faulty components, thereby simplifying maintenance, repair, and replacement procedures considerably.
Furthermore, the diagnostic function is fully accessible via HART, FF, PA, and other protocol communications, allowing alarms to manifest as either warnings or fault protection currents. It meticulously auto-diagnoses the SENSOR, ROM, RAM, EEPROM, and assesses software health. In cases where the electronic unit or measurement element sustains damage, faulty components can be expediently replaced on-site without necessitating any re-adjustments.

Simulation
The PDS Transmitter's simulation feature is ingeniously designed to replicate process states for acquiring measurement data, and also to verify the connection and output status of the transmitter circuit. The simulation output parameters encompass pressure, sensor temperature, and electronic temperature. It offers versatile simulation output modes, including fixed value or linear function simulation. During simulation, the transmitter output remains constant despite field pressure changes, and reverts to normal measurement mode following a key operation or a power-off restart, ensuring seamless transitions and reliability.
