Vibrating targets pose a particular challenge in optical measurement technology: due to constant movement, the target's position changes during detection, which can result in unclear or incorrect results. The laser can be blurred by movement or deviated from the target, making the return signal less precise or missing altogether.
Precision optical micrometers of the optoCONTROL 2700 series from Micro-Epsilon have been specially designed designed for such dynamic measurement tasks. With a sampling rate of 15 kHz and an extremely short exposure time of just 8.5 µs, they detect even vibrating or fast-moving objects reliably and with high accuracy.
Real-time tilt correction
The receiver's image matrix records the precise positioning and therefore the angle of inclination of the object in the light beam using the main line and the auxiliary line. The internal controller automatically adjusts the measured value to the object's inclination. As a result, an accurate measurement value is obtained and no measurement errors occur. Slope correction applies over the entire measurement range and can be used in measurement programs to measure outside diameter, web edge and contour.
Thanks to optoCONTROL 2700 typical measurement variables such as diameter, slit width, edge position or segment length can be precisely defined even at high production speeds, for example as part of quality assurance on the production line or machine monitoring. The system is available in measuring ranges of 10 mm and 40 mm. A particular advantage is the controller integrated in the receiver, which reduces the wiring and installation work as no external control unit is required. The precision micrometer transmits measured values via an integrated network interface and digital interfaces.
