HUMIDITY OPERATING CONDITIONS
RH Operating Conditions

The humidity sensor may be used in a range of 0…100% RH but the recommended range is reduced at elevated temperatures. This is due to the fact that quite an aggressive environment is developed when you are measuring at high humidity and at the same time at a high temperature.

 

Input ranges
Range mV 0 to 1V 0 to 2.5V 0 to 5V 0 to 10V 0 to 24mA
Resolution µV * 15.4 38.9 76.9 154 0.36µA
Input impendance Mohm 0.1 0.1 0.1 0.1 10 Ohmshunt

* input ranges can be measured at 32 Hz. At 32 Hz the maximum resolution is ten times of the above value.
Note: A YY-CU cable with integrated potential divider is required in order to connect voltage signals. Current signals require the YY-CI cable.

Signal input Lower signals (max 1V) can be processed with the standard cable YY-CS. Higher voltage levels require the connection
