Abstract

In this paper new, tensile force sensor is presented, based on Pressductor topology and single layer of ferromagnetic amorphous ribbon. Simplified operating principle of the magnetic core with orthogonal coils is described. Straight and diagonal cut sensors are compared. The load vs. induced voltage characteristics are presented, as well as possibility of higher harmonics utilization. The effect of supply current on signal amplitude and measurement hysteresis is given. The developed 'Tensductor' sensor has near-linear characteristics and is relatively easy to manufacture. The measurement range is scalable, the experimental unit had 0⁻12 N measurement range with 1% accuracy, mostly due to magnetoelastic hysteresis.

摘要

本文提出了一种基于压磁拓扑和单层铁磁非晶带材的新型拉力传感器。描述了具有正交线圈的磁芯的简化工作原理。比较了直切和对角切传感器。给出了负载与感应电压特性，以及利用高次谐波的可能性。给出了电源电流对信号幅度和测量滞后的影响。所开发的“Tensductor”传感器具有近线性特性，制造相对简单。测量范围是可扩展的，实验单元的测量范围为 0⁻12 N，精度为 1%，主要是由于磁弹滞后。
