meteocontrol compact hygro-thermal sensor
-
At a supply voltage of 24 V DC at the sensor, the load resistance (cable + input resistance data logger) should be between 600 and 700 Ohm to obtain the best measurement results.
-
The input resistance of the data logger is 40 Ohm.
-
The installation of an additional resistance (approx. 500 Ohm) improves the measurement accuracy of the sensor.
