Air duct humidity and temperature sensor FTK+ active

relativeabsoluteflange-mount

Duct sensor for measuring relative and absolute humidity, enthalpy, dew point and temperature in gaseous media of heating, ventilation and air-conditioning systems as well as clean rooms. The optional features, such as relay outputs for 2-point controllers or 2-stage 2-point controllers and color-changing LCD allow for a wide range of applications. The accuracy of the humidity sensor is 2%. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. • Application/type : Duct sensor • Purpose : Measure values • Measured values : temperature, relative humidity, absolute humidity, enthalpy, dew point • Interface : Passive, Active, 0..5 V, 0..10 V, 4..20 mA, Switch contact • Configuration : USEapp, uConfig, jumper • Sensor : Pt1000 DIN cl.
