 EE671

Epluse unveiled an airflow transmitter, dubbed EE671, which can measure air velocity up to 20m/s. Thanks to its compact design, it is ideal for mass applications in HVAC. The flow sensing element sets new standards in terms of accuracy and resistance to pollutants.

The built-in VTQ flow sensing element based on thin-film technology works on the hot-film anemometer principle. Because of its design, made possible by the use of the latest transfer moulding technology, the sensor is particularly resistant to contamination. A high reproducibility of the sensor characteristics, fast response time, low angle dependence, and long-term stability are further advantages of the sensing element.

The EE671 is available with cable or plug connection. An alignment strip on the probe and matching mounting flange simplifies installation and ensures proper alignment of the sensor. The flange enables the immersion depth to be infinitely variable.

The measured air velocity is available as linear voltage output (optional 0-1V, 0-5V, or 0-10V). The digital interface in combination with a configuration kit allows the customer to set the measurement range, to configure the output signal and to adjust the transmitter.

The EE671 is suitable for use in heating and ventilation systems, for flow monitoring and control, or for inlet air monitoring in ovens.
