intelligent pressure transmitter

UIB1 intelligent pressure transmitter is new generation digital transmitter, it is an intelligent pressure transmitter with high accuracy & stability for pressure measurement. This product is designed by using the newest achievements of digital techniques in the sensor manufacturing domain, and the design techniques of the most advanced piezoresistive pressure transmitter, as well as precise digital temperature compensation and non-linearity compensation technology. UIB1 intelligent pressure transmitter uses ultra low power monolithic and the high accuracy power source management electric circuit, this is advantageous for the computer system to carry on the data transmission through the digital interface, thus to realize the transmitter's digitization. This product is designed in 2-wire system, and can substitute analog pressure transmitter with 2-wire 4 20mA output. UIB1 has already widely been used in scientific research and petroleum, chemical industry, medicine, electric power etc. Features: *Using digital compensation technology and non-linearity revision technology *Advanced circuit design and software design *HART protocol or MODBUS protocol(RS485 interface) High accuracy, good long-term stability good *Digital communication technology Speifications pressure mediumgas or liquid compatible to stainless steelpressure ranges-1...0 0.1...600barpressure typegauge (G), absolute (A), sealed gauge (S)overload pressure150%FSoutput signal4 20mA, 0 5V, 0 10V, 1 5V, 0.5 4.5Vaccuracy0.1%FS, 0.25%FS (standard), 0.5%FS communicationMODBUS protocol (RS485interface), or HART protocolload resistanceRL = (U-12V)/0.02A (4 20mA current output) U-loop voltage (V)long term stability<0.2%FS/yearsupply voltage12 36Vcompensated temperature range 0 70°c operating temperature range-30 +80°cstorage temperature range-40 +120°ctemperature coefficient of zero0.2%FS/10°ctemperature coefficient of span0.2%FS/10°cinsulation resistance100MΩ@ 50VDCprocess connectionG1/2 or otherselectrical connectionDIN 43650 or othersmaterial of wetted part1Cr18Ni9Timaterial of pressure membrane316Lmaterial of housing1Cr18Ni9Tisealingn-Butyronitrile or fluoro-rubber sealing ring
