Abstract: An optical sensor may include a sensor head that has an optical window for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor may also include a flow chamber that includes a housing defining a cavity into which the sensor head can be inserted. In some examples, the flow chamber includes an inlet port defining a flow nozzle that is configured to direct fluid entering the flow chamber against the optical window of the sensor head. In operation, the force of the incoming fluid impacting the optical window may prevent fouling materials from accumulating on the optical window.

Abstract: An optical sensor may have multiple detection channels to detect different characteristics of a fluid. For example, an optical sensor used in industrial cleaning and sanitizing applications may have multiple detection channels to detect when a system is both clean and properly sanitized. In one example, an optical sensor includes an optical emitter that directs light into a fluid, a first optical detector that detects light transmitted through the fluid, a second optical detector that detects light scattered by the fluid, and a third optical detector that detects fluorescent emissions emitted by the fluid. The optical emitter and optical detectors can be positioned around an optical analysis area. Depending on the application, the optical emitter may be positioned to direct light adjacent a wall of the optical analysis area rather than at a center of the optical analysis area, which may increase the strength of signal on the detection channels.
