Features

High Stability

The PDS Intelligent Transmitter, a flagship innovation from Cold Valley Intelligent Technology (Shanghai) Co., Ltd., is meticulously crafted to provide unmatched precision and performance. With a remarkable basic accuracy of 0.04%FS, and the potential to achieve an extraordinary 0.025%FS, this transmitter stands as a beacon of reliability. Designed to endure the test of time, it maintains a stellar 99.9% accuracy even after a decade of uninterrupted service, thereby substantially cutting down on maintenance costs. Built with a durable metal casing and fully sealed measurement components, the PDS transmitter is engineered to resist the harshest chemical and mechanical challenges. It excels with outstanding resistance to electromagnetic interference and features state-of-the-art lightning protection, all ensuring extraordinary stability and trustworthiness.

Intelligent Diagnosis
The PDS intelligent transmitter is outfitted with a sophisticated integrated diagnostic function, offering real-time monitoring of its activity and internal conditions. When any set event threshold is exceeded, the transmitter transitions into a fault alarm state, emitting an alert current (3.6 or 22.8mA) to deliver control signals for system interlocking or seamlessly integrating with SIS security systems. In case of a malfunction, the LCD prominently displays 'Err' while automatically analyzing and identifying the faulty components, significantly streamlining maintenance, repair processes, and part replacements.
This advanced diagnostic function can also be activated via HART, FF, PA, and other communication protocols, where alarms appear as a warning or fault protection current. It allows for the automatic diagnosis of SENSOR, ROM, RAM, EEPROM, and software conditions. Should there be any damage to the electronic unit or measurement element, the defective part can be effortlessly replaced on-site, without the need for recalibration.

Simulation
The PDS transmitter's simulation functionality is an ingenious feature that replicates process states to capture crucial measurement data. It is equally effective for verifying the connectivity and output condition of the transmitter circuit. The simulation output parameters include pressure, sensor temperature, and electronic temperature. Additionally, the versatile simulation output mode offers both fixed value simulation and linear function simulation choices. Throughout the simulation, the transmitter's output remains unaffected by external pressure, reverting to the standard measurement mode following a key operation or a power-off restart.


Authorized Certification
The PDS intelligent transmitter is expertly engineered to endure a diverse array of extreme pressures, temperatures, and corrosive environments. It proudly carries national-level instrument explosion-proof safety certification (NEPSI), China General Certification CCS, along with esteemed international recognitions such as CENELEC, SIL, PROFIBUS-PA, Fieldbus Foundation, and HART.
