Abstract
A back flushable sample probe includes a hollow fitting securable to a fluid supply source and a strainer assembly disposed within the fitting. The strainer assembly includes a movable first member and a second member secured within the fitting. The first member is movable to contact the second member and form a strainer at the engaging surface between, the first and second members, where the strainer permits a fluid sample to flow through the engaging surface but prevents debris entrained in the fluid to pass therethrough. During back flushing of the sample probe, the first member disengages from the second member, causing any debris accumulated at the engaging interface to be removed from the sample probe.
