Hochtemperatur-Druckmessumformer

UPB8 high temperature pressure transmitter is designed for the measurement of high temperature medium, it uses special pressure sensors whose pressure diaphragm can be contacted by pressure medium directly. This product uses temperature radiation to isolate its amplifying circuits, this not only guarantees UPB8's small volume and good performance, but also make this product enhance the measured medium temperature range. The performance of UPB8 is very reliable after strict tests and aged screening, it is suitable for pressure measurement in many industrial sites. UPB8 high temperature pressure transmitter presently is widely used for measurement of high temperature gas or liquid in aerospace, petroleum chemical industry, metallurgy, electric power, food, medicine, scientific research etc. Features: *Suitable for the measurement of high temperature (max. 175°C), low temperature, and normal temperature medium *Reliable performance, good long-term stability *Anti-impact, anti-vibration, anti-corrosive *Reversed polar protection and current limiting protection Speifications pressure mediumgas or liquid compatible to stainless steelpressure ranges-1...0 0.04...1000barpressure typegauge (G), absolute (A), sealed gauge (S)overload pressure200%FS and 150MPa(choose smaller)output signal4 20mA, 0 5V, 0 10V, 1 5V, 0.5 4.5Vaccuracy0.25%FS, 0.5%FS(standard) load resistanceRL= (U-10V)/0.02A (4 20mA current output) U-loop voltage (V)long term stability<0.5%FS/yearsupply voltage10 30Vmediumtemperature range -20 +145°c or -20 +175°coperating temperature range-40 +135°cstorage temperature range-40 +120°ctemperature coefficient of zero0.25%FS/10°ctemperature coefficient of span0.25%FS/10°cinsulation resistance100MΩ@ 50VDCprocess connectionG1/2 or otherselectrical connectionhirschmann conector(DIN 43650) or othersmaterial of wetted part1Cr18Ni9Timaterial of pressure membrane316Lmaterial of housing304sealingn-Butyronitrile, fluoro-rubber sealing ring or welded
