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 industrial processes up to 10 Bar and 120°C

  • High accuracy measurement of flow and temperature in industrial processes up to 10 Bar and 120°C
  • Measuring range Air Velocity: 0…2 m/s, 0…10 m/s, 0…40 m/s
  • Measuring range Temperature: -40…120 °C (-40…248°F)
  • Output :0-10V/4-20mA, supply 24V AC/DC
  • Duct mount and remote probe types with different probe lengths
  • Optional display with backlight and menu buttons.

The high-end air velocity sensor element operates on the hot film anemometer principle, and which stands out by high sensitivity even at very low air speed and high insensitivity to pollution. The robust sensing probe and enclosure allow for EE75 use in harsh industrial environment as well as in applications with pressure rating up to 10 bar (145 psi).

Beside measuring air velocity and temperature, EE75 calculates the volumetric flow rate in m³/h or ft³/min based on the cross section of the duct, with an appropriate factory correction. The EE75 can be used to measure the velocity of various non-flammable and non-corrosive gases.
