The Freesense technology has been specially designed and developed to be able to withstand some of the toughest liquid processing environments where ordinary sensors are unable to be used.
Freesense currently have two solutions to meet our customer’s needs.
For users in the fermentation industry seeking to get access to new process data from within stirred bioreactors during operation, we offer a data-based mapping service based on our patented FermSense 3D. FermSense 3D is a sensor sphere designed specifically for the rough environment in an agitated bioreactor and collect data on pH, temperature and position throughout the process. Based on the data from FermSense 3D, Freesense provides a highly accurate map of your fermentation over the full process duration, enabling you to validate your process models or use the data to optimize your process directly. FermSense 3D is used as part of a tank mapping service, which includes the deployment, data analysis and presentation of the process data.
For users interested in independently gathering data in any type of liquid process environments, FS Explorer wireless data loggers have been developed. FS Explorer are sold with control software and USB radio antenna for the user to be able to operate the datalogger with ease. The FS Explorer data loggers log and store data on pH, temperature, pressure and shock on an internal flash storage, which can then easily be exported. It is also possible to see data real time, during data gathering.
In a data-based fermentation mapping project, the FermSense 3D sensor spheres are added directly into your production tank prior to fermentation start. During the fermentation the sensors spheres collect critical production parameters (continuous and simultaneous collection of pH, temperature, position and flow patterns) throughout the fermentation process, while moving around freely following the flow of the liquid. Upon completion of the production run, the FermSense 3D sensor spheres are extracted and data is analysed to produce a data-based compartment model of your fermentation. The compartment model generated from the data from your production run will then be presented to you by a Freesense data expert, giving you unique insights into what is happening at every point in the bioreactor during every step of the production process. The data can then be used to optimize the process, validate flow patterns or as input/validation for computational fluid dynamics model.
