Abstract:A 2-axis acceleration sensor,ADXL202AE,is added when onboard capacitance transducers are used to measure the load of vehicles. Its Y axis is applied to examine the forward acceleration during the process of vehicles moving and X axis to examine the obliquity of the capacitance plate when the load of left and fight side in the compartment is not in equipoise. Furthermore, the relationship between the acceleration, obliquity of the capacitance plate and the measuring result of load is analysed quantificationally.
Keywords:acceleration sensor  capacitance transducer  vehicles load measurement
