不同重力条件下气泡对电导率传感器影响的研究
摘要
针对气泡对电导率传感器输出有影响的问题
提出了不同重力条件的试验方案。经理论分析
得到气泡的存在使传感器输出变小的结论。通过地面、超重、失重试验数据
分析得出影响传感器输出的主要因素为系统流量。实验表明:流量大于300m L/min
气泡被排出
传感器输出不受影响;流量小于30m L/min
传感器受其影响较大
气泡的排出与被排出两种状态并存。真实的试验数据对传感器性能做出全面而正确性的评价。
Abstract
Aiming at problem of influence of bubbles on output of conductivity sensor
experimental schemes under different gravity conditions is proposed. Through theoretical analysis
it is concluded that the existence of bubbles makes the sensor output smaller. Through the ground
overweight and weightlessness test data
it is concluded that the main factor affecting the sensor output is system flow. The experiment shows that when the flow rate is greater than 300 m L/min
bubbles are discharged and the output of the sensor is not affected. When the flow is less than 30 m L/min
the sensor is greatly affected by it. There are two states of bubble
discharge and being discharged. The real test data make a comprehensive and correct evaluation on sensor performance.
