Environmental Sensors Air Velocity Transmitter • Low angular dependence • Easy installation • Adjustable to application requirements • HVAC applications • Remote sensor probe • Probe lenght 1m • CE, RoHS Product Description The air velocity transmitter is ideal foraccurate ventilation control applications. It operates on an innovative hotfilm anemometer principle. The thin film sensor guarantees very good accuracyatlowair velocity, which is not possible for conventional anemometers withcommercial temperature sensors or NTC bead thermistors. Moreover, the sensor is much more insensitive to dust and dirty than all other anemometer principles. This means high reliability and low maintenance costs. CGESAIRVEL isavailable withcurrentor 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.
