E+E EE451 - HVAC Temperature Sensor (Room/Duct/Outdoor Variants)

The EE451 measures accurately the temperature indoors and outdoors in building automation, HVAC and process control and enables weather-dependent temperature regulation. An optional display is available for the EE451 with analogue output.

The T measured data is available on the voltage or current output, as well as on the RS485 interface with Modbus RTU. In addition, EE451 features a wide choice of sensing elements for passive T measurement.

The compact and robust enclosure allows for easy and fast installation and unbiased detection of ambient temperature.

An optional adapter and the free EE-PCS Product Configuration Software facilitate the setup and adjustment of the EE451.
