Abstract
Disposable, pre-sterilized, and pre-calibrated, pre-validated sensor components are provided. The sensor components interact with a sensor system having disposable fluid conduit or bioreactor bag and a reusable sensor assembly. The components can include an optical bench or inset optical component or module designed to be integrated within the disposable fluid conduit or bioreactor bag, which provides an optical light path through the conduit or bag. The sensors systems are designed to store sensor-specific information, such as calibration and production information, in a non-volatile memory chip on the disposable fluid conduit or bag and on the reusable sensor assembly. Methods for calibrating the sensor and for determining a target property of an unknown fluid are also disclosed. The devices, systems and methods relating to the sensor are suitable for and can be outfitted for turbidity sensing.
