Abstract

An in-line particle sensor includes a sensor body, an illumination source, an illumination detector and communication electronics. The sensor body has an electronics enclosure and a flowthrough portion with a fluid inlet, a fluid outlet, a sample interaction region and a fluid path extending through the sample interaction region from the fluid inlet to the fluid outlet. The illumination source is disposed to provide light through at least a portion of the sample interaction region. The illumination detector is disposed to detect illumination variation resulting from illumination impinging at least one particle in the flow path in the sample interaction region. The communication electronics are operably coupled to the illumination detector to provide an indication of the at least one particle sensed by the illumination detector. The sample interaction region is configured to withstand high operating pressure.
