音叉液位开关振动频率如何设计和微调?

2014-08-22

  振动式音叉物位开关发明以来的几十年,其已经在各行各业中得到广泛应用,并且经久不衰。在研发该产品过程中,需要根据应用工况和测量对象合理设计音叉振动频率,而在生产过程中,也需要对振动叉体根据设计标称频率做适当微调谐,以便设备在实际应用时工作稳定可靠。

  音叉振动频率的经验计算公式为:

  式中:L:叉体的长度(单位为m)
     t:叉体的厚度(单位为m)
     E:杨氏模量(单位为kgf/m²)
     g:重力加速度(980cm/s²)
     ρ:叉体材质的密度(kg/m³)

  除了上述两种调整方法外,选用杨氏模量值E值大的材料,也能提高振动体的振动频率。

  计为自动化为了提高音叉物位开关的可靠性,专门设计只测量液体的液位开关和专门测量固体颗粒和粉末的料位开关,双双获得极高可靠性,并且其可测量介质的密度大大低于同行同类产品。其中,其音叉液位开最低可测液体密度低至0.5g/cm³,音叉料位开关最低可测颗粒或粉末密度低达0.008g/cm³。
