Signal Correction of Load Cell Output Using Adaptive Method

Abstract: This paper presents a method of dynamic compensation of load cell response using Adaptive technique. The case is illustrated by showing how the response of a load cell can be improved. The load cell is a sensor, whose output gives an oscillatory response in which the measured values contribute to the response parameter. Thus, a compensation technique is used to track the variation of the measured values to facilitate the investigation using response compensation. The first step is to make a mathematical model of a load cell. Secondly, the output is digitized by a proper sampler and suitable A/D converter. After verifying the simulated output, a model of an adaptive technique will be made to minimize the oscillation in the output and the corrected digital data again converted to analog form by proper D/A converter for using in real system. The whole system constitutes a dynamic sensor for achieving compensation response.
