Abstract:
1. A photo-coupled data acquisition system comprising a container having a contour wall extending upwardly from a closed bottom, for containing a sample therein, a light emitter operable to emit diffused light into the container at an initial intensity, a photodetector operable to detect a reflected intensity of the diffused light reflected by at least one of the sample and the container across the sample, and a structure connected to the contour wall and holding the light emitter and the photodetector at a predetermined height above the bottom of the container and in an orientation facing inside the container, the contour wall and the bottom being part of a bucket having an open upper end, the structure being formed by a lid securable to the open upper end of the bucket, and to which both the light emitter and the photodetector are mounted, the contour wall, bottom, and lid being opaque to prevent intrusion of ambient light inside the container, and the inner face of the contour wall and bottom being reflective to the diffused light, wherein during operation of the system, the initial intensity is attenuated by the sample in a manner that the reflected intensity can be correlated to an information value concerning a variable of interest of the sample.
