Antares Vision Group has introduced a noninvasive, inline pressure measurement system providing reliable, high-speed inspection for beverages in glass and plastic bottles. Applicable for all transparent and semi-transparent bottles, the company’s PCS700-IOT utilizes advanced laser spectroscopy technology to precisely determine whether a container headspace has appropriate pressure levels. The result is accurate, non-destructive leak detection and process optimization.
Through a technique called Tunable Diode Laser Absorption Spectroscopy (TDLAS), the PCS700-IOT analyzes specific molecules in their gaseous state—in particular, their ability to absorb light at certain telltale wavelengths. The laser beam passes through the bottles in the product-free headspace, which, for carbonated beverages like seltzer, soda and beer, enables carbon dioxide levels and pressure concentration to be measured quickly and accurately, revealing whether a leak or micro-leak is occurring. Leak-determining pressure inspection also can be performed on nitrogen-dosed products such as water and teas, as well as hot-filled beverages including various juices. For the wine sector, PCS700-IoT enables the in-line oxygen measurement to evaluate the efficiency of the inertization process after bottle closing.
