Product Description

Product Description

Introducing the PDS879 high-temperature remote pressure transmitter, an unparalleled solution for precise pressure measurement! Meticulously engineered to convert pressure readings into a seamless 4-20mA d.c. current output, it also offers the versatility of superimposed HART communication. But that's not all-experience enhanced connectivity with PROFIBUS-PA and FF communication signals. This cutting-edge transmitter empowers you with the capability for remote setting, comprehensive monitoring, and a suite of other dynamic functions, all easily accessible through advanced communication devices. Elevate your measurement solutions with this exceptional innovation!

Features

High Stability
Discover unparalleled precision with the PDS intelligent transmitter! Boasting a basic accuracy of 0.04%FS, and even reaching an impressive 0.025%FS, this device promises to retain 99.9% accuracy over a decade of continuous use. This remarkable performance translates into significant savings on maintenance costs. Encased in a robust metal shell, it features fully sealed measurement components, making it adept at handling extreme chemical and mechanical demands. Furthermore, its formidable anti-electromagnetic interference and lightning protection capabilities ensure unwavering stability and reliability, even in the harshest conditions.

Intelligent Diagnosis
Elevate your monitoring with the PDS intelligent transmitter's comprehensive diagnostic capabilities. It seamlessly tracks both operational processes and its internal state in real time. Upon crossing the predefined event threshold, it adeptly enters a fault alarm mode, delivering an alarm current (3.6 or 22.8mA) to signal system interlocking or SIS security systems. During a fault, the LCD prominently displays "Err," and the device swiftly analyzes and identifies faulty components, streamlining maintenance, repair, and replacement efforts.
This advanced diagnostic feature can be activated via HART, FF, PA, and other communication protocols, allowing alarms to be manifested as either warnings or fault protection currents. It performs automatic health checks on SENSOR, ROM, RAM, EEPROM, and software integrity. If any electronic unit or measurement element sustains damage, the defective component can be effortlessly replaced on-site without necessitating recalibration.

Simulation
Harness the power of simulation with the PDS transmitter's advanced capabilities! This feature enables the simulation of process states to obtain precise measurement data, while also verifying connections and output status of the transmitter circuit. It provides parameters such as pressure, sensor temperature, and electronic temperature, with output modes available as fixed value or linear function simulation. During simulation, the transmitter output remains unaffected by field pressure, smoothly transitioning back to normal measurement post key operation or power restart.
