Micro-Epsilon's Smart PLC Unit enables measurement values from up to eight laser scanners to be evaluated together, which is necessary in many applications such as contour measurement of large components.
The scanCONTROL Smart PLC Unit is an industrial controller for calculating measured values for laser scanners of the scanCONTROL Smart and gapCONTROL series. Customer-specific application software for the respective measurement task is included in delivery. The Smart PLC Unit evaluates, displays, stores and transmits the measurement values obtained to higher-level controllers via analog and digital interfaces.
Up to eight laser scanners can be connected to the intelligent control unit. Micro-Epsilon laser scanners are among the world's most powerful profile sensors, in terms of size, accuracy and measurement frequency. These sensors use the principle of laser triangulation for two-dimensional profile detection. They detect, measure and evaluate profiles on a wide range of surfaces. Thanks to special optics, the laser beam is widened to create a static laser line projected onto the surface of the object to be measured, instead of a laser spot. The receiving optics reproduce the light from this diffusely reflected laser line on a highly sensitive sensor matrix. In addition to distance information (z-axis), the controller also calculates the position of each point on the laser line (x-axis) from this matrix image. The values collected are then integrated into a two-dimensional coordinate system with the sensor as its origin. 3D measurement values can also be obtained in the case of moving objects or when the sensor is traversed.
Micro-Epsilon's product range includes laser line profile sensors equipped with a red or blue laser diode. Each offers its own specific advantages. As a general rule, blue laser technology is used when the red laser, which is used in common measurement tasks, has reached its limits. Unlike red lasers, blue light does not penetrate the object to be measured and reproduces a sharp line. In particular, organic or semi-transparent objects can be reliably detected. With incandescent objects, the blue laser has a maximum spectral distance from infrared light, and is therefore insensitive to the red radiation that appears with incandescent metals, for example. In general, it is important to consider which laser light will deliver the most accurate results for the specific measurement task in question.
