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
Key Specifications:
1.Two independent differential pressure sensor.
2.Measuring range (of each sensor): 0 ~ 4.0 mbar up to 0 ~ 100 mbar; ± 2.5 mbar to ± 60.0 mbar
3.Maximum static operating pressure: 50 mbar to 500 mbar
4.Maximum safe pressure: 150 mbar to 1500 mbar
5.Straight line deviation error (max): 1.0% full scale
6.Pressure connection: G 18 female threads with optional cutting ring fittings for 6 or 8 mm tube
7.Operating ambient & media temperature: -10° C to +70° C
8.Protection class: IP65 per DIN EN 60529
9.Electrical output: 4-20mA or 0-10V, 3 – wire
10.Power supply: 24 V DC AC
