Verschildruk transmitter - Fischer DE28

Differential pressure transmitter – DE28

Supplier: Fischer

The differential pressure transmitter from Fischer, type DE28, is designed for measuring overpressure, vacuum, and differential pressure in both liquids and gases. The DE28 has a measurement range between 0..400 mbar and 0..6 bar.

The DE28 transmitter operates on the simple principle of a diaphragm that moves under pressure or vacuum. The diaphragm is connected to an inductive displacement transducer, which converts the movement into a 4-20 mA electronic output. When balanced, springs on both sides of the diaphragm maintain equilibrium.

Applicability

The DE28 is suitable for building automation, including measuring differential pressure in forward and return flow in heating systems or monitoring filters, blowers, and compressors.
