Verschildruktransmitter - Fischer DE25

Differential pressure transmitter – DE25

Supplier: Fischer

The differential pressure transmitter type DE25 from Fischer has a 3-wire electrical interface. The DE25 is highly suitable for precise measurements of positive or negative atmospheric pressure and differential pressure of gases and air.

Fischer’s DE25 uses a piezoelectric sensor and can measure both positive and negative atmospheric pressure as well as differential pressure. Pressure is transmitted to the sensor through a very thin silicone membrane. A change in pressure causes a change in resistance over the piezo element. This value is sent by the microchip in the DE25 to a D/A converter for a 4-20 mA output.
The sensor’s range is from 0..4 mbar to 0..100 mbar and -2.5..2.5 to -60..60 mbar.

Applicability

The DE25 is a versatile instrument with very high accuracy. It can be used in building automation, including air conditioning and ventilation systems, determination of thermal capacity, filter monitoring, air supply monitoring, and installations in clean room and laboratory environments.
