PU/PI
Measuring ranges from ± 50 Pa to ± 100 kPa.
In addition to differential pressure, the PU/PI differential-pressure transducer also records positive and negative overpressure. The central unit is a pressure cell with a diaphragm spring made of beryllium bronze which, in accordance with the pressure difference, is displaced between two chambers. The displacement is measured, without making contact, via an inductive displacement recorder. The device does not contain any components that can rub against each other or parts subject to mechanical wear. The device is best suited for use in air-conditioning and ventilation units, for monitoring filling levels and for filter control.

The 3 or 4-figure LC display is available as an option. In addition to Pa and kPa, it can also display mmWs etc.
An optional time constant (only pressure transducer) of up to 5 s means the device can also be used under fluctuating pressure conditions and generates a stabilised output signal.
