Internal linearization, temperature compensation, high-precision measurement, simple structure, accurate measurement

Application

With the adoption of embedded micro-controller technology this product can measure the wind velocity according to the principle of micro-pressure change. Internal linearization and temperature compensation are achieved with digital technology which has completely solved the turbulent air flow problem in air tube as well as guaranteed the high-precision measurement in the condition of low wind velocity. Characterized by a simple structure, an accurate measurement, a stable performance and a high reliability, it can be used together with various types of coal mine safety monitoring systems to continuously monitor the wind velocity in the working environment.
