Clarification of Problems in Electrostatic Probe Measurement and its Application

如果使用得当，静电探头有望用于探测碳氢化合物火焰的特征。然而，只有有限数量的研究人员知道这些诊断的细节并成功地使用它们。为了使更多的燃烧科学工作者能够正确使用静电探头，在前人对静电探头特性研究的基础上，介绍了静电探头的基本特点和正确使用方法。给出了静电探头和电路的实例，并尝试解决了1)直流放大器和A/D转换器之间的噪声和最佳信号与接地，2)优化了鼻滤器，3)使探头能够用于高温空气燃烧。提出了一种原型式测量系统。在样机的基础上，静电探头的测量系统即将面市。

Electrostatic probes are promised diagnostics for exploring characteristics of hydrocarbon flames if we use those appropriately. However, only a limited number of researchers have known the details of those as diagnostics and used those successfully. For increasing the number of combustion scientists who can use electrostatic probe appropriately, I have attempted to introduce into basic characteristics and correct use of electrostatic probes on basis of previous studies on the characteristics of electrostatic probes. Examples of electrostatic probes and electric circuit are presented.Attempts have been made to solve 1) noise between DC Amplifier and A to D Converter and optimum signal and ground, 2) optimizing the Nose filter, 3) development of the probe enable to use at the High Temperature Air combustion. We propose the proto type measuring system. Based on the proto type, measurement system of the electrostatic probe will be coming to the market.
