The LFHV-2B65 duct humidity temperature duct transmitter combines a capacitance-type relative humidity sensor and a temperature sensor in one housing, both with 0…10V output. The LFHxx-2B65 humiditytemperature duct transmitter is additionally equipped with a passive temperature sensor. These temperature transmitters can be used: ▪ for checking and monitoring temperature and humidity in air duct applications (fresh air / exhaust); ▪ to avoid condensation in air duct applications; ▪ for humidification control.
