Data Acquisition from Lvdt and Its Analysis

Abstract

Different A/D converters are used for low-speed analog data acquisition in various industry.Most of these converters are not fit for high-speed analog signal. This shows a high speed data acquisition system which interface with Data card .The design is based on NI USB-6211 data card and proposed for LVDT sensor detection to realize the high-speed analogical data acquisition of multichannel sensor in the LabVIEW. The deliberate results demonstrate that the estimation accuracy can achieves 0.01mm and this framework has great shared trait and in addition extensibility. Finally compensate the non-linearity region of LVDT using neural network algorithm using MATLAB programming. LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) software and MATLAB is Used to simulate the process.
