| Abstract: | Linear variable differential transformer(LVDT) sensor is an electromagnetic switch unit widely used in apparatus and instrument.In this paper,the configuration and work principle of LVDT sensor is analyzed.The LVDT signal conditioner AD598 is used as measuring circuit to thoroughly analyze how the errors of LVDT sensor formed,the method is proposed to measure the errors and demarcate the precision.Using AD598,the convert circuit structure has been reduced and the property has been risen greatly.The experiment concludes that the LVDT based on AD598 can achieve high accuracy. |
