There are strict safety regulations in the field of industrial safety in China,but the research on monitoring the risk of non-coal dust explosion is still in its infancy.For the explosive dust deposition thickness sensor,the key technologies are the sensor hardware structure design that complies with national explosion-proof regulations and the compensation algorithm for long-term small-increase weighing sensor creep and other influencing factors.By designing a two-stage isolated DC-DC chip transformer circuit,a high-precision AD conversion circuit is used in conjunction with the weighing sensor,and calculate the measured quality through the AD value.The software is designed to com-pensate for the creep and temperature influencing factors of the weighing sensor,and the error separation algorithm is combined.Through the above methods,a sedimentary dust thickness sensor that meets the national explosion-proof re-quirements and has an accuracy of±0.1 mm is designed.
