Abstract: There is disclosed an optical radiation sensor system for detecting radiation from a radiation source. The system comprises: a housing having a distal portion for receiving radiation from the radiation source and a proximal portion; a sensor element in communication with the proximal portion, the sensor element configured to detect and respond to incident radiation received from the radiation source; and motive means configured to move the housing with respect to the sensor element between at least a first position and a second position. A radiation pathway is defined between the radiation source and the sensor element when the housing is in at least one of the first position and the second position. Movement of the housing with respect to the sensor element causes a modification of intensity of radiation impinging on the sensor element. In its highly preferred embodiment, the radiation sensor system is of a modular design rendering the sensor system appropriate for use with one or more of various radiation sources, fluid thickness layers and/or in UVT conditions. In this highly preferred form, the sensor system may have built-in diagnostics for parameters such as sensor operation, radiation source output, fluid (e.g., water) UVT, radiation source fouling (e.g., fouling of the protective sleeves surrounding the radiation source) and the like. Other advantages of the present radiation sensor system include: incorporation of an integrated reference sensor, safe and ready reference sensor testing, UVT measurement capability and/or relatively low cost and ease of manufacture.

Abstract: There is disclosed an optical radiation sensor system for detecting radia tion from a radiation source. The system comprises: a housing having a dista l portion for receiving radiation from the radiation source and a proximal p ortion; a sensor element in communication with the proximal portion, the sen sor element configured to detect and respond to incident radiation received from the radiation source; and motive means configured to move the housing w ith respect to the sensor element between at least a first position and a se cond position. A radiation pathway is defined between the radiation source a nd the sensor element when the housing is in at least one of the first posit ion and the second position. Movement of the housing with respect to the sen sor element causes a modification of intensity of radiation impinging on the sensor element. In its highly preferred embodiment, the radiation sensor sy stem is of a modular design rendering the sensor system appropriate for use with one or more of various radiation sources, fluid thickness layers and/or in UVT conditions. In this highly preferred form, the sensor system may hav e built-in diagnostics for parameters such as sensor operation, radiation so urce output, fluid (e.g., water) UVT, radiation source fouling (e.g., foulin g of the protective sleeves surrounding the radiation source) and the like. Other advantages of the present radiation sensor system include: incorporati on of an integrated reference sensor, safe and ready reference sensor testin g, UVT measurement capability and/or relatively low cost and ease of manufac ture.
