Duct Humidity Transmitter KLK-Passive

This transmitter is designed for high- and low-humidity applications in non-condensing environments. It is typically used in building automation systems for measuring and controlling humidity in locations where relative humidity must be kept constant.

This transmitter measures temperature with a passive NTC 10 sensor and an active sensor. It has a resistance output for the passive sensor data and a dual-mode output for the active sensor data. In addition, the transmitter has one dual-mode output for humidity measurement data.

This transmitter has a broad humidity measurement range and a wide temperature measurement range. You can set a custom measurement range (low and high limit) separately to temperature and humidity measured with the active sensors.

This transmitter has a P/PI controller. You can use one of the dual-mode 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.
