  Gaps in Parquet Flooring

Dear manufacturers of vinyl flooring, don't worry, we will find the gap!

From the range of RED series edge detectors the RED-50-L and RED-110-L sensors are especially suited for detecting gaps, i.e. in this application the distance of two parquet panels. These edge detectors reliably detect gaps starting from a depth and width of approx. 0.05mm.
With the supplied software the laser edge detector can be adapted to different surfaces: From dark to bright, and from matt to glossy. With a maximum scan frequency of typ. 85kHz the sensor also is excellently suited for high-speed object handling.

  Perfect Gloss for Metal Plates!

When metal plates are painted, both their color and their gloss factor must be measured after the painting process. Gloss measurement is performed inline and immediately after the painting process to allow a quick response to possible deviations of the gloss factor from the respective setpoint value.
A gloss sensor of the GLOSS series (GLOSS-15-60°) that measures the gloss factor at a distance of 15mm from the object is used for this application.

  Proper Gloss for Decor Foils

Apart from plastic foils, paper-based foils are more and more used both in the furniture industry and in the flooring sector. Nowadays decor papers for example are available for kitchens, furniture elements, and laminate flooring. However, one requirement applies both to plastic and paper-based decor foils: Constant quality and brilliant appearance must be ensured during production.
The inline gloss sensor GLOSS-15-60° that continuously measures the gloss factor of decor foils definitely makes a decisive contribution to achieving this.

  No Problems Counting Fan Blades

In the production of radial and axial fans the checking of the correct frequency response depending on the applied DC voltage is one of the final steps. The easiest method for measuring the frequency is to use a transmitted-light sensor (for example a D-LAS2-d1.0-T + D-LAS2-Q-d1.0-R-HS, featuring a switching frequency of typ. 300kHz). In many cases, however, the fan blades of the respective fan version only can be accessed from one side for testing, so that a reflected-light sensor must be used as an alternative.
The edge detectors of the RED series (RED-50-L or RED-110-L) are excellently suited for such applications.

  Counting Folds at Flex-Pipe

In the production of aluminium flex-pipes the decisive factor is not really the measured length of the flex-pipes but rather the number of existing folds, because due to the material's "accordion effect" the actual length cannot be accurately measured. In this application an edge detector of the RED series (e.g. RED-50-L or RED-110-L) is used to count the folds. During edge counting the aluminium flex-pipe is moved along the laser sensor. The sensor provides a digital output signal for every edge.

  Frequency of Compressor Wheels

The task is to measure the frequency of compressor wheels that are used in turbochargers. These wheels may reach speeds of up to 300,000 revolutions per minute. Usually these compressor wheels have about 10 blades and are made of milled aluminum. If the frequency of these compressor wheels should be determined optically it must be taken into consideration that every blade causes a signal change - which means that up to 3,000,000 switching processes must be expected per minute, resulting in a frequency of approx. 50 kHz (of the blades). Even an edge detector of type RED-50-P or RED-110-P with its maximum scan frequency of typ. 100 kHz will work up quite a "sweat" here.

  Sandpaper Grain Size Measured as Gloss

In the production of sandpaper it must be ensured that the grain size of the abrasive material (e.g. aluminum oxide or silicon carbide) always lies within the permitted tolerance range. Previously performed laboratory tests showed that the gloss factor of the sandpaper surface correlates quite well with the grain size: The smaller the grain size, the higher the corresponding gloss factor.

  Wire Counting at Stranding Machines

In the production of cables or of high-voltage lines the individual insulated conductors or aluminium wires must be stranded, which in practice is performed by stranding machines. In this process the individual conductors or wires are wound around a core wire. The core wire with relative ease can be inspected for possible wire breaks by using a suitable laser light barrier operating with the transmitted-light method.
An inspection of the outer conductors or outer wires can be realised with a correspondingly adapted edge detector of the RED series (RED-110-P-F60).

  Not always down!

Some aspects of technology very well can be compared to real life: The direction is not always up or down. After a "down" there often is an "up" again, and this also applies to edges: As a rule a rising edge is followed by a falling edge, and vice versa. 
In the series of edge detectors the RED-60-CLS-L and the RED-60-CLS-P now allow the detection of rising and falling edges.

  Perfect Gloss Measurement!

Hand-held units for measuring the gloss level have been successfully used in the industry for years, and three viewing angles have been established as a standard: 20°, 60° and 85° measured from the vertical axis. The paper industry is an exception here and primarily uses viewing angles of 45° and 75°. The gloss level is determined by measuring the direct reflection at the object surface to be inspected.

  Problems With Folds?

In the production of oil and air filters for the automobile industry these filters must reach the required throughput rate, which is achieved by folding the filter material so that it provides a large filter surface on a minimum of space. Depending on the filter type there are differences in the fold depth and in the numbers of folds.

  Welding Seam Detection With Edge Detectors

For the detection of welding seams, contrast or color sensors would seem to be the proper solution, because in most cases the welding seam optically shows a clear difference from the surrounding product surface. In everyday practice, however, it turns out that these methods involve frequent readjustment and reparameterisation.

  Detection of Transparent Edges

Conventional detectors particularly reach their limits when they have to detect and count stacked transparent objects such as plastic drinking cups of plastic caps. Especially in the process of packaging, however, it is of great importance to place the exact number of objects in a packaging unit. Such problems now can be solved with the RED series (a RED-110-L was used for this application).

  A Hazy Problem?

At first everything seemed to be quite clear, just another measurement task that we surely would manage without any problems with one of our GLOSS series sensors. According to the descriptions provided by the customer it seemed to be gloss grade measuring task, and at the beginning the only question seemed to be at which angle measurement should be performed: 20°, 60° or 85° from the vertical?

  Perfect Copy Counting

When cartons, magazines, or single sheets are packed, it must be ensured that each package has the correct number of items. In most cases such material is transported in shingled form before, as with magazines, newspapers or advertising prints, it is packed by means of a compensating stacker. Depending on the thickness of the individual copies and on their transport speed (up to 10m/s) the shingled stream may have differing heights in this process.
