Campbell Uses RFID Sensor Tags to Test Cooking Equipment

The Campbell Soup Co. is employing an RFID-based solution to test the operation of its aseptic cooking system, by measuring the temperatures of chunks of meat and vegetables as they travel through heating pipes through which a soup's liquid and solid ingredients pass and are cooked prior to being packaged. The system consists of a low-frequency (LF) RFID temperature sensor tag inserted in a solid piece of food, as well as RFID readers with antennas wrapped around certain sections of pipe.
