Description
Fischer DE22 – Low Pressure Air DP Transmitter
differential pressure transmitter for industrial applications
Make: Fischer Messtechnik (Germany)
Model: DE22
Fischer DE22 is low pressure range, accurate differential pressure transmitter for air and clean gaseous application.
Working Principle:
DE22 is based on capacitance sensor element and can measure positive gauge, negative gauge or differential pressure.
The pressure is measured directly by a micro-machined silicon-on-glass differential capacitance sensor element.
Pressure changes cause capacitance changes interpreted by the integrated electronics.
