Product Description Product DescriptionThe PDS879 high-temperature remote pressure transmitter is used for pressure measurement and converts it into a 4-20mA d.c. current output (with superimposed HART communication), PROFIBUS-PA communication signal, or FF communication signal. It allows for remote setting, monitoring, and other functions through communication devices.FeaturesHigh stabilityThe basic accuracy of PDS intelligent transmitter is 0.04%FS (up to 0.025%FS). After 10 years of continuous use, it can still maintain 99.9% accuracy, saving considerable maintenance costs. PDS intelligent transmitter uses strong metal shell and fully sealed measurement parts, can calmly cope with extreme chemical and mechanical load, at the same time has a strong anti-electromagnetic interference ability and lightning protection function, to ensure the high stability and high reliability of PDS transmitter.Intelligent diagnosisThe PDS intelligent transmitter has the integrated diagnosis function to monitor the operation process and its own state in real time. After exceeding the defined number of events, the transmitter enters the fault alarm state to output the alarm current (3.6 or 22.8mA) to provide the control signal for the system interlocking or SIS security system. During the failure, the LCD display automatically displays "Err", and automatically analyze and display the faulty parts, making the instrument maintenance, repair and replacement become more simple and convenient.The diagnosis function can also be started through HART, FF, PA and other protocol communication, and the alarm can be expressed as a warning or fault protection current. Automatically diagnose SENSOR, ROM, RAM, EEPROM, software health. When the electronic unit or measurement element is damaged, the faulty component can be replaced directly at the site without re-adjustment.SimulationThe simulation function of the transmitter can simulate the process state to obtain the measurement data, and can also be used to check the connection and output status of the transmitter circuit. The ulation output parameters include: pressure, sensor temperature and electronic temperature. The simulation output mode includes: fixed value simulation or linear function simulation. During the simulation, the transmitter output does not change with the field pressure, and returns to the normal measurement state after key operation or power off restart of the transmitter.Product Parameters Basic accuracy: ±0.04% (maximum ±0.025%)Range ratio: 100:1Response time: 90ms (data refresh time: 50ms)Range range: differential pressure 0-100 Pa-14MPaPressure of 0-1 kPa-70MPaOutput signal: 4-20 mA superimposed HART protocol communication (version HART6.0/ HART 7.0) PROFIBUS-PA fieldbus communication (version 3.02) FF Fidbus Communication (Version 6.1.1)Overload limit: differential pressure of 42MPaPressure of 105MPaEffect of the static pressure: 0.03%FS / 16MPaTemperature range: Ambient temperature-40oC ~80oC (for explosion-proof temperature range, see explosion-proof grade) Process temperature-90oC~700oC LCD temperature-35oC~80oCLong-term drift: ± 0.1%FS / 10 yearsTemperature Effect: (0.06 * r + 0.01)% / 28oC (-40oC ~80oC)Explosion-proof grade: NEPSI: Type Ex iaIICT4 Ga (Note 1) (applicable ambient temperature-40oC ~60oC) NEPSI: Intrinsic Ex iaIICT6 Ga (Note 1) (applicable ambient temperature-40oC~40oC) NEPSI: explosive type Ex dIICT6 Gb (applicable ambient temperature-40oC ~60oC) NEPSI: Dust explosion Ex tD A21 IP67 T85oC NEPSI: "n" explosion-proof Ex nACT6 Gc (applicable ambient temperature-40oC ~ + 60oC) ATEX: Ben Ex II 1 G Ex iaIICT4 Ga, ATEX: burst Ex II 1 / 2 G Ex dbIICT6-T 4 Ga / Gb IECEx: Intrinsic safety Ex iaIICT4 Ga IECEx: burst Ex dbIICT6-T 4 Ga / Gb Company ProfileCold Valley Intelligent Technology (Shanghai) Co., Ltd. stands proudly as a member enterprise of the esteemed Hanshan (Cold Mountain) Intelligent Technology Co.(hereinafter known as Hanshan Intelligent Technology Co., Ltd. group), established its formal roots in the bustling city of Shanghai in 2013.Our founding team comprises seasoned professionals hailing from top-tier international automation companies, boasting over 20 years of expertise in the automation industry, automation engineering, and a decade of consulting and implementing digital solutions.
