Detective Signal Influence Factor Analysis and Experimental Research of Magnetostrictive Liquid Level Sensor
摘要
Abstract
Magnetostrictive liquid level sensor is a liquid level measuring device. Detective signal has a direct im⁃pact on the performance of magnetostrictive liquid level sensor,so the analysis for the influence factors of detective signal is essential to optimize the performance of sensor. The influence is discussed from the structure of detection coil and parameters of current impulse. Based on detection coil,the equivalent circuit model is established,which provides a theoretical basis in establishing the coil structure parameters. The curve between detection signal and in⁃fluence factors is found through observing signal waveform change trend. And the optimal parameters are obtained. The ability of anti-jamming is improved and the output waves are also stable after optimization of liquid level sen⁃sor. These results provide a theoretical guidance for reasonable design of the magnetostrictive liquid level sensor.关键词
