Product Description

Product Description

PDS805 The Accurate Pressure Sensor Transmitter is an innovative device tailored for precise measurement of liquid, gas, or steam pressure. It masterfully converts these measurements into a 4-20 mAd. c. current, while seamlessly integrating HART communication for enhanced data transfer. Additionally, it supports PROFIBUS-PA and FF communication signals, empowering remote setting, and monitoring capabilities via sophisticated communication equipment. This powerful tool ensures comprehensive control and superior precision for your most demanding applications.

Features

High stability
The PDS Intelligent Transmitter by Cold Valley Intelligent Technology (Shanghai) Co., Ltd. sets the gold standard in pressure measurement with remarkable basic accuracy levels of 0.04%FS, even reaching an unparalleled 0.025%FS. It steadfastly maintains an astonishing 99.9% accuracy over a decade of continuous use, significantly reducing maintenance expenses. Engineered with a robust metal shell and meticulously sealed measurement components, the transmitter adeptly withstands extreme chemical and mechanical challenges. Its exceptional anti-electromagnetic interference and superior lightning protection capabilities ensure that the PDS transmitter remains a beacon of high stability and reliability under the most demanding conditions.

Intelligent diagnosis
The PDS Intelligent Transmitter is equipped with cutting-edge integrated diagnostic functions that continuously monitor operational processes and internal states in real-time. Upon surpassing predetermined event thresholds, the transmitter activates a fault alarm state, outputting an alert current (3.6 or 22.8mA) to signal control systems or SIS security systems. In failure scenarios, an 'Err' message is prominently displayed on the LCD, quickly pinpointing faulty components, thereby simplifying maintenance, repairs, and replacements for unparalleled ease and convenience.
Diagnostic capabilities are further enhanced with protocols like HART, FF, and PA, allowing alarms to be communicated as warnings or fault protection currents. The system automatically diagnoses sensor health, ROM, RAM, EEPROM, and software integrity. In instances where electronic units or measurement elements are compromised, the system allows for direct on-site component replacement without necessitating recalibration, ensuring seamless operation.

Simulation
The simulation functionality of the PDS Transmitter is a game-changer, enabling representation of process states to acquire precise measurement data. It is instrumental in verifying circuit connections and output status. Simulation output parameters encompass pressure, sensor temperature, and electronic temperature with modes like fixed value simulation or linear function simulation. During the simulation, the transmitter's output remains unaffected by field pressure, reverting to normal measurement upon key operation or a power cycle, guaranteeing optimal performance at all times.
