MWF400+ relay / LCD / BUS
Duct sensor for measuring the average temperature in air ducts. The sensor measures the current mean temperature value throughout the entire length. A spring at the connection head reduces vibrations. Mounting angles are included in the delivery content. Models with a relay output for a 2-point controller or a 2-stage 2-point controller and color-changing LCD allow for a wide range of applications. Depending on the model, the sensor can be individually configured via Thermokon USEapp. A hinged cover and tool-free wiring as well as removable cable entries ensure quick and easy installation.
