Verschildruktransmitter - Fischer DE23

Differential pressure transmitter – DE23

Supplier: Fischer

The DE23 from Fischer is a 2-wire transmitter particularly suitable for measuring very small pressure differences in gases or air, both atmospheric (positive/negative) and differential.

Fischer has equipped the instrument with a sensor capable of measuring positive or negative atmospheric pressure as well as differential pressure. The pressure is measured using a silicone-glass differential capacitive sensor element. Pressure changes are interpreted and converted into a 4-20 mA signal by the built-in electronics.

Applicability

The DE23 from Fischer is suitable for measuring very small pressure and differential pressure. This makes it especially suitable for building automation applications such as air conditioning and ventilation systems, filter monitoring, air supply monitoring, and installations in clean room and laboratory environments.
