Bestech Australia releases new sensors for non contact vacuum integrity testing of containers

Bestech Australia announces a new range of eddy current sensors from
Micro-Epsilon designed to test the vacuum integrity of cans, jars, and bottles
using a non contact measurement method.

Once preserving jars are filled and closed, they must be vacuum-tested
in fully automatic operation to immediately sort out any defective units.
During transport of the jars an eddy current sensor scans the lid shape that is
generated by the vacuum in a non-contacting manner.

The subsequent electronic unit accurately calculates the lid
bending, which directly depends on the internal pressure. After comparing this
value with a specified permissible value range, a decision is made
about the quality of the internal pressure and therefore, the tightness of the
preserves container.

Micro-Epsilon eddy current sensors allow the fully-automatic,
non-contacting vacuum test to be conducted; enable optimum adaptation to the
production process; offer almost unlimited service life without system disturbances;
are impervious to environmental influences such as moisture, pungent vapours in
the field from wet and sticky food, and temperature fluctuations; and provide a
counter for total throughput and for the number of ejected glasses.

The Micro-Epsilon eddy current sensors from Bestech Australia are
waterproof and supplied with a 3m cable and a light barrier to detect lidless or
tilted cans.
