CF 2001 series absolute pressure / pressure transmitter adopts diffused silicon isolation type sensor modules that are of high precision and high stability, converting the absolute pressure of the tested medium or gauge pressure into standard 4 ~20 mA DC electric signal through highly reliable amplifying circuit and precision temperature compensation. Elaborate packaging techniques and perfect assembling technology ensure excellent product quality and the most optimal performance of the product. The product is featured with complete types and specifications, normalized interface form, convenient adjustment of zero point and range adjustment etc, with which customer demands can be fulfilled to the most. CF 2001 series absolute pressure / pressure transmitters are divided into such three types as general type, intrinsic safety explosion proof type and flame proof type. Intrinsic safety explosion proof type and flame proof type products can be widely used in various tough and dangerous industrial environments.
