NRG RH5X Relative Humidity Sensor - Solar

The RH5X is a low-cost continuous measurement relative humidity sensor.

  RH5XC RELATIVE HUMIDITY SENSOR (#14878)
Description
Sensor type Polymer capacitor humidity sensor
Applications
  • Wind resource assessment
  • Meteorological studies
  • Environmental monitoring
Sensor range 0 to 100% relative humidity (non-condensing)
Instrument compatibility Any Symphonie Data Logger
Output signal
Signal type Linear analog voltage
Transfer function
  • Refer to individual calibration supplement for sensor-specific transfer function
  • Default values: % Relative Humidity = Voltage x 20
Accuracy
  • +/- 2% RH typical from 20% to 80% RH @ 5 to 60°C (41 to 140°F)
  • +/- 3% RH Max from 0 to 100% RH
  • Contact Technical Support for information on additional uncertainty due to temperature effects.
Calibration NIST-traceable calibration performed to verify individual sensor performs within specified accuracy limits.
Output signal range 0 to 5V for 0 to 100% RH
Power requirements
Supply voltage 12 to 30 VDC
Supply current 5 mA Max
Installation
Mounting Uses a sheet metal bracket with a hose clamp, to be mounted to the tower, under the shelter box
Tools required 8 mm (5/16 inch) nut driver or wrench
Environmental
Operating temperature range -40°C to 70°C (-40°F to 158°F)
Operating humidity range 0 to 100% relative humidity (non-condensing)
Other
  • IP55 Rated
  • Recommended range of operation is 5 to 60°C and 20 to 80% humidity. Longterm exposure to conditions outside this range may temporarily offset RH measurements (approximately 3% after 60 hours).
