KTF 1 RS485 incl. mounting flange
Duct temperature sensor/Air duct sensor with RS485 output
Application
The KTF 1 RS485 is a duct temperature sensor in IP65 housing with quickrelease screws, whose signal communicates via RS485 Modbus®-RTU and S-Bus. For detecting the temperature of gases, e.g. in ventilation and air conditioning ducts.
