Areas of Application
Whether efficient Check & Sort applications in production or demanding measuring and inspection applications, the PosCon HM is the perfect solution:
Quality inspection on test benches:
Quality inspection of rubber seals independent of the position of the object.
The PosCon HM is ideal for use in quality control on the basis of height measurements. An example of this is the control of rubber seals. In the sensor, powerful algorithms analyze up to 600 items of height information per measurement and determine the maximum height of the object, irrespective of its position. Only the PosCon HM light section sensor makes it possible to carry out this measurement, and it supplies precise, reliable measurement results with a measuring rate of up to 500Hz.
Quality inspection in process: Measuring fullness with statistical data
Especially the checking of fullness levels with solids is expected to meet stricter and stricter requirements. Thanks to its measuring principle, the PosCon HM light section sensor is the ideal solution. It not only provides the maximum fullness level, it also calculates further statistical data in the sensor, such as the minimum value, average value, differential value and the standard deviation of up to 600 items of height information. On the basis of this data, it is possible to make a more precise statement about the fullness level of solids and thus to optimize the production process.
Check & Sort applications in production:
- Thanks to the evaluation algorithms integrated in the sensor, PosCon HM sensors are a low-cost alternative for a large number of check-and-sort applications. In the Delta mode, the sensor identifies faulty products on account of their variance in form and discards these. The mode is selected quickly and easily using the integrated touch display. After the digital output has been configured, the PosCon HM light section sensor immediately provides the test result (OK/NOK).
- The PosCon HM is ideal for controlling ultrasonic welding in the production of toothpaste tubes. Thanks to the color-independent measurement, the height information is analyzed in the PosCon HM and the measured result is evaluated in the form of a delta value. In this way, open welded seams can be detected and faulty products discarded. With the statistical height data, the production process can be optimized simply, efficiently and sustainably.
PosCon HM – the calibrated light section sensor
The PosCon HM is based on the 3D light section principle. According to this, the projected laser line is reflected by the surface and projected onto a two-dimensional optical receiver in a triangulation process. The specially developed multiple lens system ensures the required optical mapping quality.
Different height figures are thus reliably obtained with the help of clever algorithms and powerful coordinate transformation functions:
- Minimum height (of the object from the reference surface)
- Maximum height (of the object from the reference surface)
- Average height (of the object from the reference surface),
- Delta height (Maximum height minus minimum height)
- Standard deviation (Measure of the spread of height values around the average value)
In the measurement mode in question, the measured result can be compared with configurable limit values, and is available in binary form at the switching output. Or the measured value can be output directly in mm on the display or at the interface.
