静电型火灾探测器本文介绍一种非常简单的静电型火灾探测器。其原理是所有的燃烧（包括无烟火灾）都发射带电粒子。传统的静电探测器测量的是电荷，而这里只是探测粒子电荷的极性。这是一个优点，因为电荷常常很小，而且难以再现。这种探测器是通用型的，特别对“无烟”火... Electrostatic fire detectors This article describes a very simple electrostatic type fire detector. The principle is that all combustion (including smokeless fire) emits charged particles. Traditional electrostatic probes measure the charge, and here only the polarity of the particle charge is detected. This is an advantage because the charge is often small and difficult to reproduce. This detector is universal, especially for “smokeless” fire...
