Overview
The MWF400+ measures the average air temperature along its 400 mm bendable copper element. A spring at the connection head reduces vibration and mounting angles are included. The output range is selectable from several presets. Versions are available with a 0 to 10 V or 0 to 5 V output, a 4 to 20 mA output, and a relay output that can act as a 2 point or 2 stage 2 point controller. LCD versions show the reading with a traffic light function, configured with the USEapp or uConfig.
