Design of Wind Speed Sensor in Mine

It is an important factor of mine-shaft safety to measure the wind velocity for the special working conditions and complicated working surroundings in mine, thus the measuring of wind velocity plays a significant role in mine-shaft safety. The measuring principles of air velocity transducer with negative temperature coefficient thermistor as its detecting element was introduced. ELICIT the corresponding various relationships between wind velocity and resistance changes are elicited. The measuring principle of wind velocity is elaboraled.
