A2G-10 differential pressure gauge for ventilation and air conditioning WIKA

Description

The A2G-10 differential pressure gauge for ventilation and air conditioning from WIKA is used for measuring the differential pressure of gaseous and liquid media.

The A2G-10 differential pressure model is used for differential pressure control in ventilation and air conditioning applications. The measuring ranges are from 0… 100 Pa to 0… 6 000 Pa. Plus/minus ranges can be achieved from -50… +50 Pa to -1,500… +1,500 Pa.

The separate construction of the pressure measurement chamber and the showroom ensures that impurities from the process air do not settle at the back of the window.

The differential pressure gauge is available in IP54 and IP65 ingress protection and in two different mounting versions.

Embedded version
The integrated version with threaded frame features a quick and tool-free installation. The built-in housing has two G 1/8-IG connectors at the rear into which the corresponding threaded threaded connectors are screwed.

Additive version
With the add-on version, the add-on housing is fixed with three screws and then the pressure measurement system is installed in the housing. The additional housing has two G 1/8-IG connectors with a lower bracket into which the corresponding threaded threaded connectors are screwed. The position of each connection can be changed by 90° by rotating the accessory housing.
