Description

The model A2G-55 Eco differential pressure transmitter is used for detecting small air flows in air-conditioning systems and for measuring low pressures in environmental, laboratory and clean room applications (air, non-aggressive gases).

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

The A2G-55 is available in a variety of unchangeable pressure ranges. Electrical analogue output signals for both measurement parameters (0 ... 10 V or 4 ... 20 mA) enable the direct connection to control systems or the building automation system. With its ingress protection of IP65, the measuring instrument is ideally suited for outdoor application.
