Gas detection
A Discussion on Pellistor Gas Sensor Responses
Sep 03 2009
Author: Dr Alan Doncaster on behalf of Clairair Ltd
Pellistor gas sensors have been used for several decades to monitor the presence of combustible gases. They provide a measure of the combustibility of the environment in which they are placed and are capable of detecting almost all combustible gases within their explosive ranges. Pellistors are used worldwide in all major applications requiring detection of explosive gas levels. This article discusses the science behind the pellistor response, why different gases respond by differing amounts and some of the factors affecting the gas response.
