Abstract

一种薄壁拉式传感器，包括一个弹性体，弹性体的两侧设有第一受力端和第二受力端，弹性体中部上下两面设有第一盲孔和第二盲孔，第一盲孔和第二盲孔之间设有薄壁，薄壁上贴有电阻应变片，当传感器受拉时，电阻应变片阻值发生变化，输出与拉力值相应的电压信号，电阻应变片贴在第一盲孔和第二盲孔的之间的薄壁上，而薄壁仅承受整个拉力的极小部分，故安全过载能力大为提高。

Description

一种薄壁拉式传感器
技术领域
本发明涉及一种薄壁拉式传感器。
背景技术
传统的拉式传感器的安全过载能力差。
发明内容
为了克服上述现有技术的缺点，本发明的目的在于提供一种薄壁拉式传感器，抗偏栽能力强。
为了达到上述目的，本发明采取的技术方案为：
一种薄壁拉式传感器，包括一个弹性体2，弹性体2的两侧设有第一受力端3和第二受力端4，弹性体2中部上下两面设有第一盲孔5和第二盲孔6，第一盲孔5和第二盲孔6之间设有薄壁1，薄壁1上贴有电阻应变片7。
本发明中电阻应变片7贴在第一盲孔5和第二盲孔6的之间的薄壁1上，而薄壁1仅承受整个拉力的极小部分，故安全过载能力大为提高。
附图说明
附图为本发明的结构示意图。
具体实施方式
下面结合附图对本发明做详细描述。
参照附图，一种薄壁拉式传感器，包括一个弹性体2，弹性体2的两侧设有第一受力端3和第二受力端4，弹性体2中部上下两面设有第一盲孔5和第二盲孔6，第一盲孔5和第二盲孔6之间设有薄壁1，薄壁1上贴有电阻应变片7。
当传感器受拉时，电阻应变片7阻值发生变化，输出与拉力值相应的电压信号，电阻应变片7贴在第一盲孔5和第二盲孔6的之间的薄壁1上，而薄壁1仅承受整个拉力的极小部分，故安全过载能力大为提高。
