Product Description Product DescriptionIntroducing the PDS873, an advanced remote pressure transmitter meticulously engineered to elevate process control precision. This cutting-edge instrument is capable of measuring pressure with exceptional accuracy, transforming these measurements into a reliable 4-20mA direct current (d.c.) output. It seamlessly integrates superimposed HART communication for enhanced connectivity. Additionally, the transmitter supports PROFIBUS-PA and Fieldbus Foundation (FF) communication signals, offering versatile compatibility with various digital communication protocols. Experience the ease of remote configuration and monitoring, empowering users with comprehensive control over settings and functions through sophisticated communication devices, ensuring streamlined operations and unparalleled efficiency.FeaturesImpeccable StabilityThe PDS intelligent transmitter is renowned for its extraordinary precision, boasting a basic accuracy of 0.04%FS, which can even reach an exceptional 0.025%FS. Even after a decade of continuous service, it confidently maintains a remarkable 99.9% accuracy, substantially reducing maintenance expenses. Crafted with a robust metal shell and fully sealed measuring components, it effortlessly withstands extreme chemical and mechanical challenges. Additionally, it excels with superior anti-electromagnetic interference capabilities and a comprehensive lightning protection feature, ensuring steadfast stability and unwavering reliability.Advanced Intelligent DiagnosisEquipped with an integrated diagnostic function, the PDS intelligent transmitter diligently monitors its operational processes and internal state in real-time. When predefined limits are surpassed, it activates a fault alarm state, effectively outputting alarm currents of 3.6 or 22.8mA, thus providing critical control signals for system interlocking or SIS security systems. During a malfunction, it intuitively displays "Err" on the LCD screen, automatically analyzing and indicating the faulty components, simplifying maintenance, repair, and replacement tasks for utmost convenience.This intelligent diagnostic capability extends through HART, FF, PA, and other protocol communications, expressing alarms as either warnings or fault protection currents. It autonomously diagnoses SENSOR, ROM, RAM, EEPROM, and software integrity. In cases of damage to electronic units or measurement elements, faulty components can be directly replaced on-site, eliminating the need for re-adjustment, thus enhancing operational efficiency.Sophisticated SimulationThe sophisticated simulation function of the transmitter masterfully replicates process states to procure measurement data, while also facilitating checks on the connection and output status of the transmitter circuit. Simulation output parameters comprise pressure, sensor temperature, and electronic temperature. The simulation output mode offers versatility with options for fixed value simulation or linear function simulation. Throughout the simulation, the transmitter output remains unaffected by field pressure, and seamlessly returns to its normal measurement state upon key operation or a power reset.Product ParametersBasic Accuracy: Meticulously engineered with a precision of ±0.04%, reaching an impressive maximum of ±0.025%.
