Description
Fischer DE23 – Very low Pressure Air DP Transmitter
very low pressure differential transmitter for air, clean gases
Make: Fischer Messtechnik (Germany)
Model: DE23
Fischer DE23 is very low pressure range, accurate 2-wire differential pressure transmitter for low positive and negative gauge pressure or differential pressure of air and clean gaseous application.
Working Principle:
DE23 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.
