Method And Apparatus For Particle Concentration Detection Using A Cloud Chamber

US Patent:
4967187, Oct 30, 1990
Filed:
May 15, 1989
Appl. No.:
7/352149
Inventors:
Jerome E. Dumas - Johns Island SC
Eric W. Harris - Moncks Corner SC
John G. MacDougal - Charleston SC
Assignee:
Research Equipment Corporation - North Charleston SC
International Classification:
G08B 2100
G08B 1710
US Classification:
340628
Abstract:
Method and apparatus for sampling the gaseous medium of a zone or area to determine the concentration, or changes in concentration, of submicron particles suspended in the gaseous medium of that area or zone using an elongated cloud chamber. A light source and a phototransistor are disposed in the cloud chamber and spaced apart so as to be electronically responsive to varying levels of light. A microprocessor is connected to a programmable memory EPROM and has pre-programmed data instructions on particle concentration levels. The EPROM sequences the microprocessor to operate the valves that sequentially sample the gaseous medium in the cloud chamber, and opens the exhaust valve in the cloud chamber to create a condition of reduced gas pressure therein. The sample of gaseous medium containing submicron particles then precipitates or condenses a portion of the cloud in the chamber in proportion to the concentration of the particles. The phototransistor measures the change in light intensity due to the concentration of the particles.
