How it Works

Traditional optical biomass probes rely on a single emitter-detector pair, resulting in a sensitivity to biomass that is highly nonlinear and limited in range. The BE2100 sensor employs an array of infrared lasers and detectors. Each of the laser-detector pairs in the array is sensitive to a different range of biomass changes. The BE2100 advantage is conferred by combining the signals from each of these pairs in a manner that linearizes its response to biomass changes over a very wide dynamic range.

There are a variety of ways to attach the BE2100 to a fermentor vessel. The patented BE2100 attachment mechanism maintains a fixed distance between the optics and the fermentor window despite variable curvature of the window (US patent 7,100,462). The BE2100 supports attachment via a strap/buckle mechanism or with a screw-in adapter, depending on the style of fermentor. Magnetic adapter sleeves are used to allow the BE2100 to be attached to different types of fermentors (patent pending).
