The model A2G-15 differential pressure gauge with electrical output signal is used for monitoring the differential pressure in ventilation and air-conditioning applications. The measuring ranges cover from 0 … 100 Pa to 0 … 6,000 Pa. Plus/minus ranges can be fulfilled from -50 … +50 Pa to -1,500 … +1,500 Pa.
Electrical output signals for both measurands (DC 0 … 10 V or 4 … 20 mA) enable the direct connection to control systems or the building automation system.
The separated construction of the measuring chamber and display area ensures that impurities from the process air do not settle on the back of the window.
The differential pressure gauge is available in IP54 and IP65 ingress protection as well as two different mounting versions.
The built-in version with threaded bezel is notable for its fast and tool-free mounting. The built-in case features two back mount connections with a G ⅛ female thread, into which matching threaded pressure connections are screwed.
With the add-on version, the add-on case is attached with three screws and then the pressure measuring system is fitted into the case. The add-on case features two lower-mount connections with a G ⅛ female thread, into which matching threaded pressure connections are screwed. The position of each connection can be altered through 90° by rotating the add-on case.
