Description
The model A2G-70 ventilation duct sensor is a relative humidity sensor with an integrated temperature measurement, suitable for direct mounting on circular ventilation pipes or rectangular ventilation ducts.
The adjustable mounting flange enables a quick installation.The illuminated LC display provides good readability, even from a distance. The model A2G-70 has a screwless cover for rapid wiring and commissioning.
The measurement of relative humidity and the air temperature as the basis of demand-orientated control/regulation is gaining ever more importance in the ventilation and air-conditioning industry. The model A2G-70 registers the relative humidity and the temperature of the air with a capacitive sensor. The sensor signals for both measurement parameters are transmitted to the control/regulation or building automation with analogue output signals (0 ... 10 V, 4 … 20 mA) or digital Modbus® protocol.
