Magnetic Displacement Sensor Based Elevator Weight Measurement

Abstract

Elevator is famous and common way for vertical transporting. Today, elevator traffic management systems are so important to reduce energy and time losses. In order to obtain time and prevent energy losses, elevator weight must be measure and control strategies must regard the weight. There are two classical methods to measure the weight. one of them works as one of and the other is based on real load cells. In this study a novel method is offered to measure elevator weight regarding easy installing and calibrating. In this study, high resolution magnetic displacement sensor is designed and characterized for elevator application. Magnetic displacement sensor is sensitive to magnetic field changing. In this study, 1cm distance are calibrated as 1000kg and output generates 0-10V voltage related to distance. Inside the sensor includes FIR sensor to reduces fluctuating. Because elevator includes rubber spring to reduce mechanical noise and shaking.
