振动传感器种类、原理及发展趋势【摘要】 振动传感器是一种能感受机械运动振动的参量( 振动速度、频率，加速度等) 并转换成可用输出信号的传感器。在高度发展的现代工业中，现代测试技术向数字化、信息化方向发展已成必然发展趋势，而测试系统的最前端是传感器，它是整个测试系统的灵魂，被世界各国列为尖端技术，特别是近几年快速发展的IC 技术和计算机技术，为传感器的发展提供了良好与可靠的科学技术基础。使传感器的发展日新月益，且数字化、多功能与智能化是现代传感器发展的重要特征。【关键词】种类；原理；发展趋势【Abstract 】: Vibration transducer is atransducer that can feel the vibration of a mechanical movement parameters (frequency of the vibration velocity, acceleration, etc.) and converted into usable output signal of the sensor. At the height of the development of modern industry, modern testing technology to digitization, information management has become an inevitable trend of development, and testing system for the front end is the sensor, it is the soul of an entire test system, is listed as a leading-edge technology around the world, particularly in recent years, the rapid development of IC technology and computer technology, the development of a sensor provides a good and reliable scientific and technology base. Place the sensor development, Crescent IK, and multipurpose digital, is a modern and intelligent sensor development, an important feature. 【Keywords 】: type , principle , inevitable trend of development振动传感器的分类1、相对式电动传感器电动式传感器基于电磁感应原理，即当运动的导体在固定的磁场里切割磁力线时，导体两端就感生出电动势，因此利用这一原理而生产的传感器称为电动式传感器。相对式电动传感器从机械接收原理来说，是一个位移传感器，由于在机电变换原理中应用的是电磁感应电律，其产生的电动势同被测振动速度成正比，所以它实际上是一个速度传感器。2、电涡流式传感器电涡流传感器是一种相对式非接触式传感器，它是通过传感器端部与被测物体之间的距离变...
