HTF RS485
Sleeve temperature sensor / Cable temperature sensor with RS485 output
Application
The HTF RS485 is a sleeve temperature sensor with remote electronic housing IP65 with quick-release screws, whose signal communicates via RS485 Modbus®-RTU and S-Bus. The HTF is used to measure the temperature of liquid and gaseous media. For example: Installation with thermowells in liquid media.
