E+E EE441 Specifications
EE441
Strap-on Temperature Sensor
The EE441 strap-on sensor measures reliably the temperature (T) on round
ducts and pipes and is optimized for heating systems (warm and cold water
pipes) or solar collectors.
Analogue, Digital and Passive Outputs
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.
Easy Installation
The compact enclosure and the stainless steel hose clamp allow for easy and
fast installation on pipes with diameter from 25 to 175 mm (0.98”…6.89“).
Configurable and Adjustable
An optional adapter and the free EE-PC Product Configuration Software facilitate the setup and adjustment of the EE441.
