Strap-on Temperature Sensor


The EE441 measures accurately the temperature on round ducts and pipes and is optimized for heating systems (warm and cold water pipes) or solar collectors.

EE441 strap-on temperature sensor

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.
