Usage precautions

Usage precautions

  • When the sensor is not used, to maintain the precision, it is recommended to store it in the delivered package (in the closed anti-static bag) without opening under the following conditions :
                     Temperature range: 10 to 50 ºC
                     Humidity range: 20 to 60 % RH
    Do not use antistatic polyethylene bags (light blue, pink or rose pink color).
  • The relative humidity value greatly depends on the humidity condition.
    When measuring the surrounding temperature/humidity, be sure to confirm there is no heated part on the installation surface.
  • Use M3 pan head screws for mounting.
    The tightening torque for the case should be 0.5 N·m or less.
  • This sensor has output impedance of 1kΩ to avoid damage due to external noise.
    The impedance attenuates according to the input impedance of the signal input device.
    Use a device with as high input impedance as possible - at least 100kΩ.
  • This sensor cannot be used in dew condensation conditions.
    If this is the case, refer to the RHT series.
  • Do not use the sensor in the following environmental conditions:
    - Where there is water or moisture
    - Where there are corrosive gases
    - Where there is oil  
    - In freezing temperatures or dew condensation
    - Dusty locations
    - A place exposed to direct sunlight or radiated heat"
  • Vacuum away any serious dust contamination or else a malfunction may result.
  • For other precautions, refer to “General Precautions” for infrared temperature sensors.
