OptiSense develops a new coating thickness inspection system for the battery cells of BMW Group

For a battery to be competitive, it must be inexpensive to manufacture and above all it must be safe. Together with Sturm Maschinen- & Anlagenbau GmbH in Salching and another integrator, OptiSense developed a system for testing the insulating coating of the battery cells, thus making an important contribution to the safety of the new batteries.

Our tube sensor celebrates (into) the first of May

Maypole is the name given to a decorated tree or tree trunk that is erected on the eve of May 1 according to ancient custom. With a maypole of a special kind we bring this old Germanic tradition into modern times: Our Industrial Tube sensor acts as a maypole trunk for the decorated wreaths on this first weekend of May.

Surrounded by flapping ribbons, the Dance into May is apparently a pleasant break from the daily routine of industrial testing for our Tube.

Walpurgis night in Haltern

While the descendants of Walburga in the Harz Mountains are still on the move on traditional brooms on April 30, the witches of Haltern are swinging through the air again this year with powerful propulsion to chase away winter and evil spirits - as the picture tells us.

It shows with a little wink of the eye that the OptiSense sensors are not only used for precise coating thicknesses measurement, but in exceptional cases sometimes serve as flying vehicles for supernatural beings.

In the spirit of Goethe we greet with "Heißa, Walpurgisnacht" all big and small witches, devils as well as ravens - and wish you a relaxing and sunny first of May!

Very positive PaintExpo experience

During the four days of the event, exciting new customer contacts were made and concrete project inquiries discussed at the very busy OptiSense booth.

Spring Fever

Sunday it begins - the colorful, sunny Easter season! The entire OptiSense team wishes you a busy Easter bunny and a happy egg hunt.

By the way: Our sensors have exchanged their tiny measuring spots for huge ears for Easter...
