High quality measurement devices for montoring and controlling of medium differential air pressures in the HVAC (Heating, Ventilation, Air-Conditioning) industry.

These measurement devices detect the differential pressure with a membrane sensor, which measures the differential pressure by a mechanical strain due to the pressurisation. In order to get an optimal longterm stability the sensor is calibrated automatically and periodically during its operation. This allows to achieve the best accuracy, reproducibility and stability.


Range of use

The PascalMaxx membrane differential pressure sensors are suitable for medium pressure ranges between 200 and 2000 Pa. The automatic zeroing allows a maintenance free and reliable use and offers a real added value for the operation of HVAC plants.
