Description

The model A2G-50 differential pressure sensor is used for measuring differential pressures of gaseous media in ventilation and air-conditioning applications.

It is based on the piezoresistive measurement principle. This compact differential pressure sensor offers excellent performance and high quality at an attractive price.

Electrical analogue output signals for both measurands (0 … 10 V or 4 … 20 mA) or the digital Modbus ® versions enable the direct connection to control systems or the building automation system.

The pressure range as well as the unit and the response time can be individually adapted in the instrument via jumpers.

The measured differential pressure is also shown on the LC display and transmitted via the analogue or digital output signals. The LC display and the clear menu navigation enable a time-saving and simple commissioning.
