Abstract

一种流体负压测量传感装置,由感应弹性膜片, 密封腔体、杠杆传动机构、永磁体、磁性开关组成,腔 体内与被测压强的容器连通,腔体外与大气连通;弹 性膜片周边固定在腔体上并作为腔体的一个面,膜片 上连接一杠杆传动机构。当容器内出现负压时,膜片 收缩,带动杠杆转动,杠杆上的永磁体靠近磁性开关, 接通电源,本实用新型可以测量微小负压并远距离传 递信号。

Description

本实用新型涉及流体压强测量技术,具体是一种流体负压测量传感装置。
已有的测量流体负压的真空表及其他仪表,很难测量微小负压,并不能远距离传递信号。
本实用新型的目的,就是提出一种结构简单,运行可靠,能测量微负压并将信号远距离传递的装置。
本实用新型的目的是这样实现的:流体负压测量传感装置包括感应弹性薄膜片,密封腔体、杠杆传动机构永磁体、磁力开关,弹性薄膜片周边固定在腔体上并作为腔体的一个面,腔体内与被测压强的容器连通,腔体外与大气连通,弹性薄膜片上连接一杠杆传动机构,杠杆的一端装有一永磁体,磁力开关装置在永磁体附近。
当被测容器内出现负压时,弹性膜片在大气压强的作用下收缩,带动杠杆转动,杠杆一端的磁铁靠近或离开磁性开关,接通或断开电源,实现远距离传递负压信号。
由于本实用新型采用杠杆传动机构,可以将膜片的微小伸缩放大,因而可实现测量微量负压,同时可以将信号进行远距离传递。
下面结合附图和实施例进一步说明本实用新型。
附图是剖视图。

感应弹性薄膜片(7)的周边固定在腔体(9)上,并作为腔体(9)的一个面,腔体(9)通过连通管(10)与被测压强容器连通。腔体(9)的外部通过大气连通口(4)与大气连通;杠杆(13)可以绕着量程调整架(11)转动,一端装有永磁体(3),膜片(7)通过传动杆(8)与杠杆(13)连接。
当被测容器内压强出现负压(小于大气压)时,膜片(7)向下运动,通过传动杆(8)使杠杆(13)克服弹簧(2)拉力向顺时针方向转动,永磁体(3)向下靠近磁性开关(6),使常开磁性开关(6)接通。调整螺丝(12)与弹簧(2)配合,用来调整测量灵敏度。
