Product Description Product DescriptionDiscover the PDS843 differential pressure transmitter, a marvel of engineering designed to precisely measure and control the differential pressure and flow of a variety of media including liquids, gases, and steam. This cutting-edge device effortlessly converts measurements into a reliable 4-20mA d.c. current output, enhanced with superimposed HART communication for seamless integration. Additionally, the transmitter offers PROFIBUS-PA and FF communication signal options, ensuring versatile connectivity. Experience the convenience of remote configuration, comprehensive monitoring, and a suite of advanced functionality, all accessible via sophisticated communication devices, making your operations smoother and more efficient.FeaturesHigh StabilityThe PDS Intelligent Transmitter is engineered with a remarkable precision level of 0.04%FS, and can achieve an impressive 0.025%FS at its peak accuracy. Even after a decade of continuous operation, it boasts an astounding 99.9% precision maintenance, significantly reducing maintenance expenses. Crafted with a robust metal shell and fully sealed measuring components, this device confidently withstands extreme chemical and mechanical stresses. It is fortified with robust anti-electromagnetic interference properties and a sophisticated lightning protection mechanism, ensuring unparalleled stability and reliability.Intelligent DiagnosisEquipped with advanced integrated diagnostic capabilities, the PDS Intelligent Transmitter meticulously monitors both operational processes and its own internal status in real-time. Upon surpassing predefined event thresholds, it shifts to a fault alarm state, outputting a distinct alarm current (3.6 or 22.8mA) to deliver crucial control signals for system interlocks or SIS security frameworks. If a failure occurs, 'Err' is prominently displayed on the LCD, alongside an automatic fault analysis and display of the affected parts, simplifying maintenance and facilitating swift repairs or replacements.This diagnostic prowess is further enhanced with activation via HART, FF, PA, and other communication protocols. Alarm signals can be tailored to reflect warning or fault protection currents. It seamlessly performs automatic diagnostics on SENSOR, ROM, RAM, EEPROM, and software health. Should an electronic unit or measurement component become compromised, on-site replacement is straightforward, negating the need for recalibration.SimulationHarnessing a sophisticated simulation function, this transmitter adeptly replicates process states to procure measurement data, while also facilitating checks on transmitter circuit connectivity and output status. Simulation output parameters include: pressure, sensor temperature, and electronic temperature. With options for fixed value simulation or linear function simulation, the simulation output remains unaffected by field pressure variations, resuming normal measurement operations after a key operation or power cycle.Product ParametersBasic accuracy: Achieve precision like never before with an impressive ±0.04% accuracy, reaching up to a maximum of ±0.025%!Range ratio: Experience unmatched flexibility with a phenomenal range ratio of 100:1.Response time: Swift accuracy in no time!
