Features
Unparalleled Stability The PDS Intelligent Transmitter redefines precision with a basic accuracy of 0.04%FS, and an impressive option of up to 0.025%FS. Even after a decade of relentless operation, it promises to uphold an astounding 99.9% accuracy, significantly slashing maintenance expenses. Encased in a robust metal shell and fully sealed for superior protection, this transmitter effortlessly withstands extreme chemical and mechanical challenges. It boasts exceptional resilience against electromagnetic interference and incorporates advanced lightning protection to ensure unwavering stability and dependability.
Advanced Diagnostic Intelligence The PDS Intelligent Transmitter is equipped with cutting-edge diagnostic capabilities, offering real-time monitoring of operational processes and its own status. Upon events surpassing predefined thresholds, it triggers a fault alarm state, outputting an alert current (3.6 or 22.8mA) to initiate control signals for system interlocking or SIS security systems. During any malfunction, the LCD screen prominently displays "Err", enabling swift identification and repair of faulty components, thus streamlining maintenance, repair, and replacement procedures with ease and convenience. This intelligent diagnostic feature can also be activated via HART, FF, PA, and other communication protocols, with alarms signaled as warning or fault currents. It seamlessly diagnoses SENSOR, ROM, RAM, EEPROM, and software health. Should the electronic unit or measurement component incur damage, replacement can be swiftly executed onsite without necessitating recalibration.
Comprehensive Simulation Capabilities The transmitter's simulation function is engineered to replicate process states for acquiring precise measurement data. It is adept at assessing the connection and output status of the transmitter circuit. The simulation output parameters encompass pressure, sensor temperature, and electronic temperature. It offers versatile simulation output modes: fixed value or linear function simulation. During simulation, the transmitter output remains unaffected by field pressure, reverting to its accurate measurement state post key operation or power-off restart. This ensures seamless integration and operation in any setting.
