                                AV66 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 AV 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 temp erature sensors or NTC bead 
                                thermistors.The AV66 sensor is much more insensitive to pollution than all other anemometer 
                                principles. This increases reliability and reduces maintenance costs.AV66 series are available with  
current or voltage output,he 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 |
