Features

High stability
The PDS815 Series Pressure Measurement Device proudly boasts basic accuracy levels of 0.04%FS, reaching up to an impressive 0.025%FS. Even after a decade of continuous operation, it sustains a remarkable 99.9% accuracy, significantly reducing maintenance expenses. Crafted with a robust metal shell and entirely sealed measurement components, it effortlessly withstands extreme chemical and mechanical stresses. Coupled with exceptional anti-electromagnetic interference capabilities and a lightning protection feature, it empowers the PDS transmitter with unparalleled stability and reliability.

Intelligent diagnosis
Equipped with advanced integrated diagnostics, the PDS intelligent transmitter continuously monitors operational processes and its own status in real-time. Should event thresholds be surpassed, it transitions into a fault alarm state, outputting a distinct alarm current of 3.6 or 22.8mA, facilitating control signals for system interlocking or SIS security mechanisms. During a malfunction, an 'Err' message is prominently displayed on the LCD, with automatic fault analysis and display of the affected components, simplifying maintenance, repair, and replacement tasks.
The diagnosis feature extends its capabilities through HART, FF, PA, and other communication protocols, where alarms manifest as warning or fault protection currents. It automatically scrutinizes SENSOR, ROM, RAM, EEPROM, and the software's health. In the event of damage to the electronic unit or measurement component, direct site replacement of the faulty part is feasible without the need for re-adjustment.

Simulation
The transmitter's simulation function adeptly replicates process states to gather measurement data, while also verifying the connection and output conditions of the transmitter circuit. Simulation output parameters encompass pressure, sensor temperature, and electronic temperature, utilizing either fixed value simulation or linear function simulation. During simulation, the transmitter output remains unaffected by field pressure changes, seamlessly reverting to normal measurement mode following key operation or power-cycle restart.
