Abstract
Description
Reason for development: - Uniform and cost-effective painting of, for example, car parts requires fast and cost-effective quality control of the density of paint solutions. State of the art - This is achieved by means of a density sphere which is inserted into a paint solution at a precisely defined depth on a weight measurement and allows very accurate statements about the density of the paint solution by determining the buoyancy force. - For this purpose, a so-called gamma sphere is used, which, as a submersible body, allows conclusions to be drawn about the density of the liquid from the increase in weight after immersion, according to the archimetric principle. - The ball complies with the standard DIN EN ISO 2811-2. - The density is influenced by the composition of the varnish and its temperature. - A disadvantage is the current inaccurate adjustment and complicated, contamination-prone subsequent cleaning process for existing density sphere measurements. Advantage over the state of the art: - mm-accurate retractable ball - Rotatable ball bearing for releasing tiny air bubbles - Easy cleaning through combination of measurement with adjacent cleaning option - No contamination when using paint Reference symbol list

Claims
[1] Suspension of the measuring sphere on a lightweight and precisely adjustable device which can be lowered to millimeter accuracy by means of gear reduction. [2] The measuring sphere is rotatably mounted [3] Gears can be made of plastic or metal [4] Gears and racks can have straight teeth or helical teeth. [5] Knurled wheels for raising and lowering are mounted on both sides and allow both left- and right-handed people to work. [6] By rotating the entire suspension, the sphere can be cleaned in a cleaning vessel installed next to it and be available for the next measurement as quickly as possible. [7] The cleaning device is attached separately to an arm [8] The cleaning device is swivel-mounted and height-adjustable.
