Sensors for measuring differential pressure. Used in air ducts, faninlet nozzles (e.g. in air conditioning box devices), roof fans, etc.
The differential pressure sensor is connected to the ventilation system by two pressure connections. The differential pressure thus acts on a silicone membrane, the change in position of which is evaluated electronically.
The sensor generates a 0 – 10 V signal proportionally over the respective measuring range. Depending on the connected control unit, the control can thus be made based on differential pressure or air flow.

The sensors have switchable measuring ranges.
With three versions, the pressure range from 0 up to 6000 Pa can be covered. Each version has four calibrated, selectable measuring ranges.
Through the gradation of the units, exact measuring results with only three versions are possible..
