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.
