 Overview

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)

Features

  1. Line speeds up to 2,000 cpm, detection accuracy to 0.005 in (0.127mm)
  2. Adjustable Signal profile capture window for improved signal processing
  3. Four algorithms to calculate Profile, Height, Cocked and Contour
  4. Programmable gain and offset parameters for improved inspection range
  5. Auto-tracking reject limits within the controller accommodate temperature and pressure fluctuations during production​​
