Compact design / Measurement of the flow velocity / 
Thin-film sensor element / Easy installation / Analog output 

The airspeed transmitter EE671 is a very compact air velocity sensor. The small design in combination with a thin-film sensor element makes it possible to use this versatile transducer, especially in mass applications. Typical applications are the monitoring of heating and ventilation systems, ventilation controls or supply air monitoring of furnaces. Insensitivity to dust and other contaminants enables good reproducibility and long-term stability. The installation is quick and easy and the immersion depth is infinitely adjustable during installation. The air speed transmitter EE671 outputs a linear voltage signal of 0 ... 1 V, 0 ... 5 V or 0 ... 10 V to the respective evaluation unit.
