Working Principle:

DE39 is based on microprocessor based electronic module which process analog signals received from integrated pressure sensors. This electronic module compute pressure difference, which can be displayed and processed. The interpretation allows to set two independent switching points and provides an electrical output signal proportional to differential pressure.

Integrated pressure transmitters are based on ceramic measuring system.
