Description
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. Compound measuring ranges can be fulfilled from -50 … +50 Pa to -3,000 … +3,000 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 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 in two different mounting versions.
Special features
- Electrical output signal DC 0 … 10 V (3-wire) or 4 … 20 mA (2-wire)
- Simple and fast mounting via threaded bezel
- Separated construction of measuring chamber and scale range
- Integrated sealing element for direct mounting in a ventilation duct or instrument panel
- Available as a built-in or add-on version
