MWF400+ relay / LCD / BUS

Duct averaging temperature sensor with flexible sensor rod for measuring the average temperature in gaseous media, e.g. in ventilation and air conditioning ducts. The devices with relay output for a 2-point controller or a 2-stage 2-point controller and color-changing LCD allow a wide range of applications. Depending on the model, the sensor can be individually configured via Thermokon USEapp. Tool-free opening, closing and wiring as well as removable cable entries ensure quick and easy installation.
