| Abstract: | The paper introduces an apparatus based on the principle of eddy current for detecting the internal vacuum or pressure in food cans. This apparatus is equipped with two sensors. By the subtraction of electric signals from the sensors it can measure the amount of internal vacuum or pressure. It can also display and print the measuring results. Using USB interface it can cooperate with the upper machine. the apparatus is portable, precise and friendly. |
