Air velocity Transmitters



EE65 Series

Air Velocity Instrument for Measurements in HVAC Applications EE65 air velocity transmitters are ideal for accurate ventilation control applications. They are operating on an innovative hot film anemometer principle. The E+E thin film sensor guarantees very good accuracy at low air velocity, which is not possible for conventional anemometers with commercial temperature sensorsor NTCbead thermistors.

EE65 series are available with current or voltage output, the measuring range and the response time can be selected with jumpers by the user. Low angular dependence enables easy, cost- effective installation

Technical Data

  • Measuring range : 0...10 rn/s: 0...15m/s; 0...20m/s (adjustable by jumpers)
  • Accuracy : ±0.2m/s+3% mv
  • Outputs : 0...10 V or 4...20 mA(adjustable by jumpers)
  • Working Temperature : - 25 to 50°C


EE75 Series

The EE75 series air velocity transmitters were developed to obtain accurate measuring results over a wide range of velocities and tem peratu res.

A high-quality hot film sensor element based on cutting- edge thin film technology ensures maximum sensitivity, even at lowest mass flows. At the same time, the innovative probe design produces reliable measuring results at high flow velocities of up to 40m/s (8000fVmin). The integrated temperature compen- sation minimises the temperature cross-sensitivity of the EE75 series which, combined with the robust mechanical design, allows it to be used at processtemperatures between -40 to + 120°C(-40 to 248°F).

In addition to air velocity and temperature values, the transmitter calculates the volumetric flow rate in m3/h or ft3/min. The crosssection of the duct needsto be determined forthis purpose and thevolumetricflow rate can be displayed and directed to one of the analogue outputs. The EE75 series can be used to measure the velocity of other gases as well, although a correction hasto be applied to the unit at the factory.
