Abstract:
An optical radiation sensor device for detecting radiation in a radiation field having a thickness. A preferred embodiment of the device includes a radiation source and a radiation sensor element positioned to receive radiation from the radiation source. A motor (or other motive means) is provided to alter the thickness of the radiation field from a first thickness to a second thickness. The sensor element is capable of detecting and responding to incident radiation from radiation source at the first thickness and at the second thickness. The optical radiation sensor device allows for determination of radiation (preferably ultraviolet radiation) transmittance of a fluid of interest.
Abstract:
There is disclosed an optical radiation sensor system. The system includes a sensor device (140) and a cleaning device (115). The sensor device detects a nd responds to radiation from a radiation field (170) and includes a surface (155) that is movable with respect to the radiation field between a first position in which the surface is in the radiation field and a second positio n in which at least a portion of the surface is out of the radiation field. Th e cleaning device operates to remove fouling materials from at least a portion of the surface in the second position. The cleaning device may be a chemical cleaning device, a mechanical cleaning device or a combined chemical/mechanical device.
