文摘:简要介绍了几种料仓高料位和极限高料位检测报警装置的结构和工作原理,并就它们的性能特点和使用效果进行了比较。 - The traditional level measuring methods can n ' t meet our demand because the subjective investigated is in such a poor systemic condition that the temperature is a little high and there ' s so many mill dust and steam there . in this article we perform systemic discuss and research against the dynamic level measuring method under special working condition on the basis of analyzing kinds of level measuring technique in and abroad . first we establish the pressure distribution mathematic model in storage bin and then deduce the mathematic relation between level height and the uniform stress on the bottom of the bin and designed a resistance compressive stress sensor used for the special condition and put forward a resoivement according to its zero excursion existing in practical use
由于本研究系统被测对象环境温度较高且潮湿，同时料仓中有大量粉尘及蒸汽，因此传统的料位检测方法不能满足本测试要求。本文在分析国内外各种物位检测技术的基础上，针对特殊工况下动态物料高度的检测进行了系统的探讨与研究。首先建立了料仓中的压力分布数学模型，推导出料位高度与仓底均布压力间的数学关系式，并据此设计了中温电阻应变式压力传感器，同时对它在实际应用中存在的零点漂移等问题提出了改进措施，提高了传感器性能，解决了上述特殊工况下动态物料检测的技术难题。
