CF2001 Digital • Intelligent Direct Connection Pressure Transmitter

 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.
