一种基于铁基非晶态合金压磁效应的膜盒式压力传感器
An Aneroid Pressure Sensor Based on the Magnetoelasticity Effect of Fe-Base Amorphous Alloy Ribbon
摘要
Abstract
A new kind of aneroid pressure sensor based on the magnetoelasticity effect of Fe-base amorphous alloy ribbon was developed. At first its operation principle, structure, output characteristic and the choice of some major parameter were discussed. Secondly through the pressure experiment, the sensor's static characteristic of as well as the influence of magnetic field strength on the output was analyzed. The experimental result shows the sensor's the maximum linearity error is 1.29％ F. S, the maximum repetitive error １.56％ F. S, and the maximum sensitivity is 0.3675mv / kPa. In addition the sensor has some characteristic such as, good temperature stability, reliability,simpler structure, low costs and extensive measuring range.关键词
