Features

High stability
Experience unparalleled precision with the Highpeak PDS821, boasting an impressive basic accuracy of 0.04%FS, and an even more remarkable 0.025%FS. Even after a decade, this precision marvel maintains a 99.9% accuracy rate, significantly reducing maintenance expenses. Encased in a robust metal shell with fully sealed components, it effortlessly withstands harsh chemical and mechanical conditions. Its superior resilience against electromagnetic interference and lightning ensures enduring stability and reliability.

Intelligent diagnosis
Our PDS intelligent transmitter is equipped with an advanced integrated diagnostic feature, continuously monitoring both operational processes and its own status. Upon reaching set event thresholds, it seamlessly transitions to a fault alarm mode, emitting an alarm current of 3.6 or 22.8mA, thus providing critical control signals for system interlocking or SIS security frameworks. During malfunctions, the LCD prominently displays 'Err,' automatically pinpointing and revealing affected components, streamlining maintenance, repair, and replacement procedures.
Initiate diagnostic functions effortlessly using HART, FF, PA, and other communication protocols. Alarms can be configured as warnings or fault protection currents. This intelligent system autonomously assesses SENSOR, ROM, RAM, EEPROM, and software integrity. In the event of electronic unit or measurement element failure, on-site component replacement is hassle-free, eliminating the need for recalibration.

Simulation
Harness the power of simulation with the Highpeak PDS821, where you can effortlessly simulate process conditions to gather critical measurement data, while also verifying circuit connections and output statuses. Simulation outputs encompass pressure, sensor temperature, and electronic temperature, with options for fixed value or linear function simulations. Throughout the simulation, transmitter outputs remain unaffected by actual field pressure, reverting to standard measurement mode upon key operations or a power cycle.
