Description

外测超声波液位计的传感器安装装置
技术领域
本实用新型涉及一种外测超声波液位计的传感器安装装置。
技术背景
众所周知,外测超声波液位计的传感器是通过先发出透过罐壁的声波信号然后采集液位高度来实现测量的,而超声波液位计的传感器是利用耦合剂完全和罐壁贴合达到真空的状态,使超声波的信号在衰减很小情况下透过罐壁进入液体中,到达液面的返回波再透过罐壁返回到超声波传感器,根据声波返回的时间和声音的速度计算液位高度。
目前,传感器和罐壁之间只有耦合剂,没有其他密封措施;因罐壁有一定的弧面,而传感器表面是平整的,这样传感器和罐壁之间就有一定的缝隙;传感器上的耦合剂长期被雨水冲刷就会减少,从而增大声波的衰减,时间长了影响仪表的正常测量。
发明内容
本实用新型的目的在于:提供一种外测超声波液位计的传感器安装装置,利用外力压紧密封圈,安装牢固,密封性好,避免声波衰减,提高测量的稳定性
本实用新型的技术解决方案是:该传感器安装装置包括底座和密封圈,底座利用强磁吸附在罐壁上,涂有耦合剂的传感器通过螺纹方式安装在底座上并在密封圈作用下拧紧贴合罐壁。
本实用新型结构简单,安装方便,通过压力让传感器和罐壁接触部分的空气向外排出,使传感器和罐壁之间形成真空状态,实现密封圈和罐壁完全贴合,达到传感器和罐壁的完全密封,避免声波衰减,提高传感器测量的稳定性
附图说明
图1为本实用新型安装结构示意图。
图2为图1的受力示意图。
图中:1底座;2传感器;3罐壁;4密封圈;5耦合剂。
具体实施方式
如图1所示,该传感器安装装置包括底座1和密封圈4,底座1利用强磁吸附在罐壁3上,涂有耦合剂5的传感器2通过螺纹方式安装在底座1上并在密封圈4作用下拧紧贴合罐壁3。
如图2所示,底座1吸附在罐壁3上,先在传感器2上加上密封圈4再通过螺纹方式安装在底座1上,拧紧传感器2使耦合剂5中的空气排空。
