RPTF RS485
Pendulum room temperature sensor with RS485 output
Application
The RPTF RS485 is a pendulum temperature sensor with remote electronics housing IP65 with quick-release screws. The signal of which communicates via RS485 Modbus®-RTU and S-Bus. For recording the temperature especially in larger rooms and halls. The RPTF RS485 (globe thermometer) determines the effective radiant component or also the effective radiant heat at the measuring point.
