Explosion Proof Dual Sensor DP Transmitter

Working Principle:
-Fischer DE44 Ex is based on dual piezo-resistive sensing element. The pressure is measured directly by piezo-resistive resistance bridge that is formed on surface of an integral silicon diaphragm in each sensor chamber.
Key Features:
1.Two independent differential pressure sensors
2.Robust design, over-pressure protected
3.Selectable pressure unit
4.Signal output with possibility of spreading and inverting 5.characteristic curve with any offset (optional)
6.Characteristic conversion of output via 3….30 entries tablets)
7.Fully programmable via PC based EU03 module
8.Large LED Display
