Space Humidity Sensor – 0-5 VDC
DRAWN BY: B. CREWS
*Chart Notes:
1. First, be sure that +24VAC power is being supplied to the sensor. Second, set the
meter to DC volts and connect the meter between ground and the 0-5 VDC input
terminal on the controller board or between the 0-5 VDC output terminal on the
sensor and its ground terminal. Use an accurate humidity measurement device to
determine RH (relative humidity) such as an aspirating psychrometer. Use the
Output VDC column to read the Output Voltage corresponding with the RH
percentage measured with the psychrometer. If the measured voltage is within 3%
of what is listed for the corresponding RH, then the sensor is functioning properly.
