What can we measure?
Dimensions, tolerance, sorting, element recognition
Dimensions can be measured in various ways. In some circumstances, one sensor can measure full dimensions for small objects. In the case of larger details, the measurement can be carried out using sensors that move along one edge, thus measuring the dimensions of the object. An alternative is to measure the dimension with a static sensor and moving measuring objects, as is usually the case with assembly lines.
Thickness: sheets of metal, foil, rubber, insulation, layer, board
Thickness measurements are mainly used in process control and quality assurance, eg for the control of extrusion systems or 100% checking of pipe diameters. We offer measurements using non-contact displacement sensors, guaranteeing high accuracy, speed and zero emission. Depending on the needs of the application, there is a possibility of one-sided or two-sided inspection of the thickness of details.
If objects are loaded with some kind of mass or move freely at a certain distance, there is always more or less distortion of the object. For larger objects, the measurement of this stiffness can be made using a variety of distance sensors. In the case of measuring a small element, it is necessary to use very precise measuring systems. Sensors in the WObit offer allow you to measure the accuracy of the trillion parts of the meter.
Diameters, nevertheless, rank, co-axis
The diameter of the object can be determined in various ways. If the center of the object is known, a single sensor is sufficient for measurement, the result of which is evaluated with the position of the center point or axis. If the center point is not known, the diameter is measured directly with the help of two sensors. The distance information here is also evaluated together. In special cases, if the object's opacity allows it, the determination of the diameter can also be made directly with the help of the confocal sensor.
Each visible body emits a light, which is why the color can be used to evaluate objects. With the help of sensors, we can sort products by color, check incoming goods, detect colored and printed characters, control the intensity and color of the LED, and much more.
The level of filling can be measured directly or indirectly in many ways by means of displacement sensors. The measurement of the filling level of solid bodies is comparable to the distance measurement. In the case of fluids, it is usually used with the confocal method. WObit offers a lot of different options thanks to a wide range of different sensors in its offer.
Elevation height, elevation
Lifting height is a factor that must be measured very often. The lifting height measurement is necessary wherever automated lifting processes simplify daily work.
Positioning, centering, deviation, setting
Different parts or products must be often placed in a specific place in production systems or during automatic movements. In this way, the sensors can send distance information to the controller or perform full system control by means of signals.
Welding robots with automatic welding are an example of automatic adjustment. Depending on the material from which the part is made, which is to be positioned, different sensors are used.
The width of the object is a very important aspect of dimension control. Width in some circumstances may have been interpreted as thickness, which is why it can be solved with the help of thickness measurement.
For the measurement of width, different measuring principles apply depending on the size of the object. In the case of large objects, such as strip material or packaging, the measurement data from two sensors is usually calculated.
When the two edges of the object are connected together, there is always a gap between them. If the gap has to meet technical or visual requirements, please check its size in terms of size. The laser scanner series scanCONTROL is ideally suited for the overall measurement of the gap. For precise measurement of the gap on the track, also point laser sensors from the optoNCDT family are used.
Temperature is a critical factor in many processes and often needs to be measured. Non-contact infrared measurement is often a better alternative compared to tactile methods. Stationary IR sensors are suitable if the temperature has to be continuously measured in one place, and mobile devices are used for mobile use.
Distance measurement, often referred to as displacement, describes the measurement of the distance between two points. The distance is determined in the measuring technique by the distance of the sensor from the target. In this way, distance measurement can also be determined as a measurement of displacement, distance or position. Measurements displaced in geometric measuring technology can be found in almost all application areas. We always take into account different criteria by selecting the appropriate sensor for the application.
