2.2 Description
The model A2G-70 ventilation duct sensor is a humidity probe with an
integrated measurement of the relative humidity and temperature.
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
A2G-70 registers the relative humidity and the temperature of the air
with a capacitive sensor. The sensor signals for both measurands are
transmitted to the control/regulation or building automation with analogue
output signals (0 ... 10 V, 4 ... 20 mA) or digital Modbus
