Abstract

本实用新型磁摆式振动传感器属于一种测试物 体发生机械振动的敏感器件,其特征是由磁摆和线圈 组合而成。它具有灵敏度高、可靠性高、制造容易和 经济适用的优点,可以广泛的用于测试各种物体是否 发生机械振动及振动的强度。

Description

本实用新型属于一种振动传感器。
现有的电磁式振动传感器结构都比较复杂,因而制造难度大并且可靠性也不够高。
本实用新型的目的是用比较简单的方法制造灵敏度高、可靠性高、经济适用的振动传感器。
本实用新型磁摆式振动传感器,其构成的要点是:在线圈附近设置磁摆,设置的要点是磁摆摆动时能使线圈中产生感生电动势。
本实用新型磁摆式振动传感器与已有的电磁式振动传感器相比,它同时具有灵敏度高、可靠性高、制造容易和经济适用的优点。
附图是磁摆式振动传感器的示意图。
下面对照附图对实施例作祥细说明:
如附图所示:在基板(15)上设置有线圈(4)和线圈(9),它们的引出线分别为(13)、(14)和(11)、(12)。基板(15)上还设置有用于安装轴的金属板(1)和(5),金属板(1)、(5)的上端分别安装有轴承(2)和(6),轴(7)安装在轴承(2)和(6)上,(3)和(8)是连杆,用于连接永磁体(10)和轴(7)。另外,永磁体(10)的磁力线方向是从一个平面出发进入另一个平面。从上述结构可以看出,当永磁体(10)发生摆动时,线圈(4)和线圈(9)中的磁通量就会发生变化从而产生电动势,线圈(4)和线圈(9)的引出线(13)、(14)和(11)、(12)就会输出信号。

Claims (4)

1、一种磁摆式振动传感器,其特征是在线圈附近设置磁摆。
2、按照权利要求1所述的磁摆式振动传感器,其特征是所述的磁摆是由永磁体或电磁体构成。
3、按照权利要求1所述的磁摆式振动传感器,其特征是所述的磁摆是由一个或多个磁体构成。
4、按照权利要求1所述的磁摆式振动传感器,其特征是所述的线圈是由一组或多组构成。
