Gas sample probes are designed for extracting a representative portion from the gas sample source in a pipe to the analyzer sampling system, and finally the gas analyzers. gas sample probes form a critical point between process and sample conditioning and analysis system.They extract sample gas from the process stream and supply it to the analysis system. They should already remove undesirable particulates at the sampling point and avoid cold spots thus preventing false measurements.
In addition it works as a filter, keeping dirt, and unwanted moisture out of the extracted gas sample. A well designed probe for sample extraction, reduces sample times, gets a better response time, reduces sample volume, and eliminates dead volumes.
