New Air velocity Transmitter for 0.2 to 20m/s (40 to 4000 ft/min)

The new miniature air velocity transmitters, series EE575 and EE576 of E+E Elektronik (Austria), allow accurate measurements of flow in air and gases. The EE575 measures velocities up to 20 m/s (4000 ft/min).

The EE576 is specifically designed for the measurement of low flows up to 2 m/s (400 ft/min).

Applications for these transmitters are found in HVAC systems, handling and controls for intake and exhaust of air and laminar flow monitoring. Equipped with a newly developed sensor head and utilising the proven E+E hot-film element, already tested a million times in the automotive industry, these transmitters are less sensitive to dust and dirt than conventional hot-wire elements.

The design with a probe length of 150 mm (6 inch) and the integrated electronics can be considered very compact. This allows for the use in applications where mounting space is limited. The alignment strip along the side of the probe and the matching mounting flange secures the positioning of the sensor and the immersion depth of the probe is infinitely variable. That saves time and prevents incorrect installation.

The series can be supplied in the range of 10-29 Vdc and provides standardised linear output signals of 0-5V or 0-10V. With a temperature range of -20....60 °C (-4....140 °F) and the electrical connection through a 0.5m (1.5 ft) or 2m (6 ft) long fixed cable, the series EE575 and EE576 ensures highest application- and mounting-flexibility.
