Instrumented spheres are used worldwide in food processing chains to locate bruising risk zones and to prevent quality loss of commodity. Risk zone location and optimisation of machine settings can be executed with a satisfying accuracy by comparing test results mutually, but measurement data are often hard to interpret, especially if predictions are desired on real damage. An extensive knowledge of the instrumented device and indications on the bruise susceptibility of a product are two indispensable conditions for successful damage prevention and reduction. As data acquisition techniques become more sophisticated and the autonomy of the measurement equipment tends to be better, the new generation of electronic potatoes, such as the Danish made PTR 200, seems promising for bruise prevention purposes. This is mainly due to improved memory capacity and more accurate data acquisition techniques.
