The model A2G-70 ventilation duct sensor is a relativehumidity sensor with an integrated temperaturemeasurement, suitable for direct mounting on circularventilation pipes or rectangular ventilation ducts.

The adjustable mounting flange enables a quick installation.The illuminated display provides good readability, even froma distance. The model A2G-70 has a screwless cover forrapid wiring and commissioning.

The measurement of relative humidity and the airtemperature as the basis of demand-orientated control/regulation is gaining ever more importance in the ventilationand air-conditioning industry. The model A2G-70 registersthe relative humidity and the temperature of the air with acapacitive sensor. The sensor signals for both measurementparameters are transmitted to the control/regulation orbuilding automation with analogue output signals (0 … 10 V or 4 … 20 mA) or digital Modbus® protocol.
