Air duct temperature sensor MWF400+ passive

NTCPt100Pt1000

Duct sensor for measuring the average temperature in air ducts. The sensor measures the 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. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. • Application/type : Duct averaging sensor • Purpose : Measure values • Measured values : temperature • Interface : Passive • Sensor : Pt1000 DIN cl.
