Catalog excerpts

Measurement of Lowest Velocity EE66 air velocity transmitter series are designed for high accuracy measurement of lowest air velocities. It is the ideal solution for laminar flow control and special ventilation applications. The E+E thin film sensor is operating on an innovative hot film anemometer principle. This guarantees excellent accuracy for air velocity down to almost 0.15m/s, which is not possible for conventional anemometers with commercial temperature sensors or NTC bead thermistors. The E+E sensor is much more insensitive to pollution than all other anemometer principles. This increases reliability and reduces maintenance costs. EE66 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. An integrated LC display and a version with remote sensing probe are also available. The configuration equipment allows air velocity adjustment of the sensor.
