ACD Rotating Vane Sensor is totally made of metal parts and can stand to rigorous industrial conditions. It consists of a Chemically Etched Stainless Steel Turbine, fitted on a Brass shaft with Stainless Steel pins, which is pivoted on re-enforced Jewel Bearings, making it extremely sensitive to minute changes in the air-flow. All other parts are of Aluminum. Non-contact transducer is insensitive to vibrations, dust, temperature, humidity, and ultrasonic radiation.
