Twin Proximity Technology
Proximity Technology has been used for decades to detect low vacuum in food cans. However, recent widespread use of bi-metal Easy Open (EZO) ends (steel ends with aluminum pull-tab) has presented a challenge for the traditional technology. The TapTone Twin Proximity Sensor is designed to detect and reject low vacuum and no vacuum steel cans with EZ-Open can ends (pull-tabs) at production speeds up to 525 feet per minute.
The new twin proximity sensor combines the inspections of Proximity-1 and Proximity-2 with an enhanced algorithm offering improved resolution across the lid profile. TapTone offers the twin proximity sensor on both the PRO Series and T550 Systems. (Not supported on HMI)
