CF2002 Integrated Digital • Intelligent Transmitter

General View

 CF 2002 integrated 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 2002 integrated  transmitter series can be widely used
in various tough and  dangerous industrial environment.
