Abstract
A device is disclosed that creates and delivers diluted representative samples of a processed medium, flowing as a process stream in a conduit, for the analysis by a particle measurement instrument. The device includes an extraction conduit that includes a probe end extending into the process stream. The probe end includes a pitot-like opening adapted to receive therein a portion of the processed medium. A diluent delivery conduit is housed substantially within and in coaxial alignment with the extraction conduit, forming a sample delivery passage therebetween. The diluent delivery conduit is arranged to emit a stream of diluent into the processed medium entering the probe end creating diluted representative samples of the processed medium. The diluted representative samples flow through the sample delivery passage to a sampling chamber of the particle measurement instrument, where they are analyzed.
