Duct Humidity Transmitter KLK

KLK duct humidity transmitters measure relative humidity and temperature inside ventilation ducts. They are designed for high- and low-humidity applications in non-condensing environments. They are typically used in building automation systems for measuring and controlling humidity in locations where relative humidity must be kept constant.

Duct Humidity Transmitter KLK

These transmitters have a broad humidity measurement range and a wide temperature measurement range. You can set a custom measurement range (low and high limit) separately for both humidity and temperature measurement.

The transmitter has one humidity output and one temperature output. You can select the output signal mode separately for each output during commissioning. The available output signal modes are voltage (Vdc) and current (mA). The voltage output is scalable.

The transmitter has a PI controller. You can use one of the outputs as a control output to keep humidity or temperature within the configured range. The controller can control the output according to one measurement value or according to the maximum selection of all values.

You can commission all models using the ML-SER commissioning tool.
