Highly Accurate Air / Gas Velocity Sensor for Industrial Applications The EE75 air velocity (v) and temperature (T) sensor is optimized for best measurement results in challenging air flow applications in most various industries. Outstanding Measurement Performance With its multipoint v factory adjustment the EE75 meets the highest accuracy requirements. The E+E thin film sensing element employed operates on the hot film anemometer principle, which stands for excellent accuracy from 0.06 m/s (12 ft/min) up to 40 m/s (8000 ft/min) and low angular dependency. The integrated temperature compensation combined with the robust mechanical design, makes the EE75 capable of process temperatures from -40 °C (-40 °F) up to 120 °C (248 °F). Versatility The EE75 is available for duct mount as well as with remote probe in various probe lengths. The remote probe types feature different cable lengths and pressure tight versions up to 10 bar (145 psi). The IP65  NEMA 4 /  rated metal enclosure facilitates easy installation and maintenance. The v and T measured data is available on two current or voltage analogue outputs. In addition to v and T values EE75 calculates the volume flow V' in m³/min or ft³/min. Configurable and Adjustable The setup and adjustment of the EE75 can be easily performed using the configuration software and USB interface cable included in the scope of supply.

Angular Dependency The innovative design of the probe head minimises the effect of the angle of inflow (yaw angle) on the measuring result. The deviation of the measuring value remains < 3 % up to a yaw angle α of ± 20° between the direction of inflow and the sensor element's longitudinal axis.
