EE671 is a compact air velocity probe for HVAC applications. The built-in flow sensing element VTQ combines the advantages of state-of-the-art E+E thin-film manufacturing and of the newest transfer molding technology.

It operates on the hot-film anemometer principle and ensures high accuracy and excellent long-term stability. The flow sensing element ist very robust and highly insensitive to contamination.

EE671 is available with fixed cable or M12 connector. The alignment strip on the probe and the matching mounting flange within the scope of supply simplify installation and precise positioning in the air flow. The flange enables the immersion depth to be infinitely variable.

The measured air velocity up to 20 m/s (4000 ft/min) is available as linear voltage output 0 - 1 V, 0 - 5 V or 0 - 10 V. The digital version of EE671 with Modbus RTU interface facilitates integration into modern building automation systems. With an optional configuration kit it is easy to scale the output, set the Modbus parameters and perform the adjustment of the probe.
