ALTF 2 RS485 incl. cable tie

Contact temperature sensor/pipe contact sensor with RS485 output

The ALTF 2 RS485 is a pipe contact temperature sensor in IP65 housing with quick-locking screw whose signal communicates via RS485 Modbus®-RTU and S-Bus. For recording the temperature by means of surface measurement on pipes (e.g. cold and hot water) or on heating lines for heating control.
