Abstract: A turbidity measurement system (100) with an improved thermal behavior is provided. A turbidity measurement system (100) includes an analyzer (102) and one or more turbidity sensors (104, 106). Each turbidity sensor (104, 106) includes a source of illumination and a semiconductor-based illumination sensor. The dark current of the semiconductor­based illumination sensor is measured when no illumination is provided by the source. This measured dark current is then used to provide a dark current­ compensated turbidity measurement.

Abstract: The invention relates to recording of position-specific optical measurements of substances such as foodstuff, building materials, combustion products etc. The invention provides online, in-situ recording of wavelength absorption spectra in substances, performed without removing a sample from the substance. In inhomogeneous products, the position correlated to each spectrum allows for extraction of both average values for larger regions as well as specific values characteristic for smaller individual portions. In a preferred embodiment, a probe with two elongate arms has light guiding and light collecting means for recording infrared absorption spectra of portions between them, as well as means for determining an insertion distance into the product. The invention may be applied to as different substances as diary products (cheese, cream, milk), fruit, berries, seeds, meat, vegetable and animal fat, animal feed, water, wine, beer, lemonades, oils, rubber and plastic materials, gypsum and plaster, cement and concrete mixes, paints, glues etc.

Abstract: Methods and systems for detecting oil proximate to a body of ice is disclosed herein. An example system includes an energy emitter disposed proximate to a first surface of a body of ice. An energy detector is disposed proximate to a second surface of the body of ice. The energy detector is used to map a distribution of oil proximate to the body of ice based, at least in part, on differences in energy transmitted through the body of ice.

Abstract: The disclosure describes various embodiments that utilize optical sensor to characterize attributes of a liquid. Some sensor configuration continue to function properly even after scaling begins to reduce the visibility of photochemical sensors that measure the attributes of the liquid. This allows significantly longer continuous operating periods and lower maintenance costs.
