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, EE441 features a wide choice of sensing elements for passive T measurement.

The compact enclosure and the stainless steel hose clamp allow for easy and fast installation on pipes with diameter from 25 mm to 175 mm (0.98"...6.89").

An optional adapter and the free EE-PCS Product Configuration Software facilitate the setup and adjustment of the EE441.

EE441 FAQ

  • What is the difference between a 2 wire and a 3 wire current output?

    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.
