Scoop probe

A probe tip for a sample retrieval system including an inlet pipe and an outlet pipe, the probe tip comprising:

• an elongated, hollow body having a distal end, a proximal end, and a central axis;
• an inlet port formed in the distal end of the body, the inlet port including an opening for facing a process flow to receive a sample of a process fluid from the process flow, the inlet port including an inlet passage directing the sample in a direction along the central axis towards a proximal portion of the inlet port, the inlet passage having a non-constant cross-sectional area with non-parallel radii of curvature defined by an outer radius and an inner radius, the outer radius being larger than the inner radius, the outer radius decreasing along a length of the inlet port from the opening to the proximal portion;
• an inlet tube in fluid communication with the proximal portion of the inlet port and configured to receive the sample from the inlet port and direct the sample towards the proximal end of the body to be received by the inlet pipe;
• an outlet tube connected to the proximal end of the body and configured to receive a returned portion of the sample from the outlet pipe;
• and
• an exit port formed in the body, the exit port configured to be in fluid communication with the outlet tube to receive the returned portion of the sample from the outlet tube and expel the returned portion into the process flow in a direction away from the process flow, the exit port located at a position closer to the proximal end of the probe tip than a position of the inlet port.
