Data Acquisition and Control of a New Electromagnetic Force-Displacement Sensor Using National Instruments ‘‘LabVIEW’’ Software
Authors: , ,
Abstract: A new electromagnetic force-displacement sensor is presented. Its operating principle is based on the fundamental laws of electromagnetism (Faraday-Lenz law) and the mechanical properties of a spring. The active elements are two coils made by a wire of 60 μm in diameter. The sensor signal is acquired using a high precision DAQ card, processed and stored on the computer using a LabVIEW Program. The average accuracy of the sensor is about Δd=1μm, and as a force sensor is about ΔF = 1μN. This sensor could be successfully used for the manufacture of several measuring instruments.
