NEW INNOVATION IN ELECTRONIC MEASURING SYSTEM USING LVDT SENSOR
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 6
Abstract
In industry field, common A/D converter chips are widely used for low-speed analog dataacquisition.Most of common A/D converter chips are not fit for the requirements of high-speed vary analog signal. This paper presents a high-speed dataacquisitionsystem based on LVDT. Design, simulation, implementation and testing of an inductive displacement sensor based on a Linear Variable Differential Transformer (LVDT) controlled by a single chip electronic module with 8 bit RISC microcontroller. LVDTdevice is widely used systems for measuring physical quantities like displacement, force or pressure.The design is based on PAC-1.0 card is proposed for LVDTsensor detection and realized the high-speed digital dataacquisition of multichannel sensor digital signals in the method of software polling mode. This paper aims to present an experimental device, which measures the displacement of inner diameter and outer diameter. This displacement is measured with a very high degree of accuracy, by means of inductiveprobe. The probe and its associated electronics system convert the displacement into a proportional voltage. The measured results of application indicate that the measurement precision can reaches 0.1 μm, and 1 μm. This system has good commonality as well as extensibility.
