The T measured data is available on the voltage or current output, as well as on the RS485 interface with Modbus RTU or BACnet MS/TP protocol. 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.

Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
