ATF 2 RS485
Exterior/damp room temperature sensor with RS485 output
Application
The ATF 2 RS485 is an exterior temperature sensor in IP65 housing with quick-release screws and external stainless steel sensor tube. The signal of which communicates via RS485 Modbus®-RTU and S-Bus. For recording the exterior temperature in damp areas. Such as weather sensors for mounting on exterior walls, in cold storage and greenhouses, in halls, in the industrial sector and in agriculture. Exterior areas, installation is preferably on the north side or in a protected location. In direct sunlight, use the sunshade.
