Air Velocity Sensor Transmitter

Air Velocity Transmitter for HVAC  Applications
EE65           air velocity transmitters are ideal for local 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 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.
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 installtion.
An integrated LC display and a version with remote sensing probe are available.

The EE75 Series air velocity transmitters were developed to obtain accurate measuring results over a wide range of velocities and temperatures.

A high quality hot firm sensor element based on cutting edge thin film technology ensures maximum sensitivity. Even at lowest mass flows. At the same time, in innovative probe design produces reliable measuring results at high flow velocities of up to 40 m/s .

The integrated temperature compensation minimizes the temperature cross sensitivity of the EE75 series which, combined with the robust mechanical design, allows it to used at process temperatures between 40 to +120oC

In addition to air velocity and temperature values the transmitter calculates the volumetric flow rate in m3 /h, or ft3 /min. The cross section of the dust needs to be determined for this purpose and the volumetric flow rate can be directed to one of the analogue outputs.

The configuration software included in the scope of supply allows to choose the appropriate output parameter and freely scale the disply range and signal level of the two analogue outputs. In addition user Friendly calibration of air velocity and temperature and the adjustment of key parameters (e.g.response time of velocity measurement , low flow cut of points, etc) are supported as well.

An optional illuminated  with two control buttons integrated in the cover is available. In addition this enables changes of the configuration to be made directly  on the unit.

The EE75 Series has a robust metal housing to protect against possible damage in rough industrial environments. There are five different models providing a comprehensive range of mounting option.
Model A for Wall mounting
Model B for djct mounting
Model C with remote probe
Model E with remote probe, pressure light up to 10 bar. (145ps)
Model P for djct Mounting, pressure light up 10 bar (145ps)
The EE75 series can be used to measure the velocity of other glasses as well, although a correction has to be applied to the unit at the factory.
