UPB9 pressure transmitter uses high quality pressure sensors with isolated stainless steel diaphragm as sensing elements, it is tested by computer automatically and made laser trimming compensation for zero and sensitivity. The output of UPB8 is amplified to 4 20mA standard output by using special amplifier, simultaneously the output signal can be displayed through LCD indicator at working site. After long-term aging tests and stability tests, this product's performance is very reliable, it is suitable for the pressure measurement and control in bad working conditions, and presently widely used in petroleum, chemical industry, metallurgy, electric power etc. Features: *3-1/2 LCD displaying at working site, simultaneously give 4 20mA signal output *High performance-to-price ratio, high accuracy, long-term stability *Electric shell is cast-aluminium material , IP65 protection *Reversed protection, current limiting protection *Anti-corrosive, the anti-attrition, the anti-impact *Flush membrane and the tantalum diaphragm option 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 load 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°coperating temperature range-30 +95°cstorage temperature range-40 +100°ctemperature coefficient of zero0.3%FS/10°ctemperature coefficient of span0.3%FS/10°cinsulation resistance100MΩ@ 50VDCprocess connectionG1/2 or otherselectrical connectionM20×1.5material of wetted part1Cr18Ni9Timaterial of pressure membrane316Lmaterial of housingcast aluminiumsealingn-Butyronitrile or fluoro-rubber sealing ring
