Convolution Profiling System (CPS)
The Jodon CPS-2000 is designed to inspect serpentine convolution samples produced by a fin mill. These fins are used in heat exchanger elements used in radiators, heaters, condensers and evaporators. The cooling fin convolution trains exit at a very high rate of speed, making on-line measurement extremely difficult. As a consequence, the CPS-2000 is used as an off-line measuring system to precisely gauge dimensional characteristics against published values. The CPS-2000 can be configured to gauge virtually any fin.
The CPS-2000 utilizes two extremely precise laser distance sensors to measure the profile of each convolution. One laser measures the rear-facing profile while the other measures the front-facing profile. Using a sophisticated differential process, the laser outputs are combined such that a very precise measurement of each profile is attained. These measurements are used to compute convolution height, contact radius, convolution symmetry (slant), fin density, and a variety of additional measures, depending on fin type.
These lasers are mounted to precise X, Y and Z translation stages. These stages allow for incredibly repeatable scans across the width of the sample (X). Multiple regions (Y) can be scanned in order to compare results across the height of the sample. The (Z) axis controls the distance between the sample and lasers, allowing for a wide range of sample heights to be measured.
