The thick of it

摘要

Sencon has entered into a ￡200,000 Knowledge Transfer Partnership with City University London to develop a measurement tool for improving the quality control of canned food, drink and aerosol products. The sensor and control systems developer is collaborating with the university to build low-cost optical sensing systems that are capable of measuring the absolute thickness of coatings on cans. This will enable manufacturers to more accurately check that cans are the correct colour and provide defence against contamination. Manufacturers currently calibrate a film's thickness using capacitive sensors.
