Humidity Transmitter KLHJ 100

Application: KLHJ 100 humidity transmitters are designed for accurate detection of relative humidity and temperature in various environments. These transmitters are suitable for applications where precise monitoring and control of humidity and temperature are essential, such as climate control systems in buildings, warehouses, and industrial facilities.

Features:

  • Dual Sensor Detection: Utilizes a capacitive sensor for relative humidity measurement and an NTC10 sensor for temperature measurement, ensuring accurate and reliable data acquisition.
  • Flexible Output Signals: Provides linear output signals for both humidity and temperature, which can be configured to either 0…10V or 4…20mA signals during commissioning, offering flexibility to integrate with different control systems.
  • High-Quality Sensors: Equipped with high-quality sensors that guarantee long-term stability and wide measurement ranges for humidity (0...90 %RH) and temperature (-40...+50 °C), ensuring reliable performance in diverse environmental conditions.
  • Sensor Protection: Sensor elements are protected by plastic filters, safeguarding them from environmental contaminants and ensuring durability.
  • Mounting Options: Can be mounted on walls using screws, offering easy installation and positioning. Additionally, sensors can be installed in ducts using the flange on the sensor probe, providing versatility in deployment.
  • KLHJ 100-N Variant: Features a display that alternates between displaying humidity and temperature readings. The display can be fixed to show either humidity or temperature by adjusting the jumper on the back of the display board, providing user flexibility.
