Product Description
FST800 3051 DR Calibration Liquid Gas Steam Differential Pressure Transmitter adopting the German advanced MEMS Monocrystalline silicon sensor chip and the world's unique Monocrystalline silicon suspension design, to achieve the international leading overpressure performance, to ensure the signal is excellent stability. Embedded German original imported pressure capsule and signal processing module, differential pressure transmitter achieves the perfect combination of static pressure and temperature compensation, and achieves high measurement accuracy and stability in a wide range of static pressure and temperature.
Product Features
♦ High acuracy: Measure high acuracy in the range of -1-1kpa, which can be stable used while compressed to -50-50pa. Standard accuracy of calibration range:±0.075 ;
♦ Excellent overpressure performance in small range: 1 kPa standard range, chip back overpressure reachs 1MPa, 6 kPa standard range, chip back overpressure reachs 2MPa
♦ Excellent environmental suitability: The intelligent static pressure and temperature compensation 
protect transmitters from the temperature effects, static pressure and overpressure,so that the consolidated measure error will be the minimum. 
♦ Flexible compression of range: S1 range ratio: 10:1 S2 range ratio: 10:1 
♦ Excellent operability & convenient to use: Variety of display functions(mA ,Pa , kPa, MPa, bar, mbar,%, psi ,mmH2o; Quickly adjust through built-in threebuttons; Remote debugging through mobile APP; A variety of corrosion-resistant materials; With comprehensive self-diagnosis function
Application Application
