Air Velocity Transmitter for

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 velo-

city, which is not possible for conventional anemometers with commercial

temperature sensors or NTC bead thermistors.

Moreover, the E+E sensor is much more insensitive to dust and dirt than

all other anemometer principles. This means high reliability and low

maintenance costs.

The EE65 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.

The configuration equipment allows air velocity adjustment of the sensor.
