HIGH PERFORMANCE OPTICAL MICROMETERS WITH INTEGRATED INDUSTRIAL ETHERNET
recision sensor supplier Micro-Epsilon has updated its compact, high performance optoCONTROL 2700 LED micrometer with Industrial Ethernet interface options (EtherCAT, Ethernet/IP and PROFINET) that help simplify integration into existing automation and control systems. New functions have also been added including full, 360° inspection of rotating components. The optoCONTROL 2700 is characterised by exceptional precision, high measurement rate and easy handling. Two models with measuring ranges of 10 and 40 mm cover a wide range of applications in automation and quality assurance. The micrometer supports high-precision measurement of diameter, gap, segment and edge. Active tilt correction enables precise detection of objects, even if they are tilted up to 63°.
REAL-TIME COMMUNICATION VIA INDUSTRIAL ETHERNET
The optoCONTROL 2700 is now available with integrated EtherCAT, EtherNet/IP and PROFINET interface options. This allows the micrometer to be integrated into existing automation and control architectures without requiring additional gateway solutions. The connection to higher-level bus systems is based on common standard protocols (TCP/UDP), which means that measured values are provided quickly and reliably in real time. This simplifies system integration, reduces the effort involved in commissioning and simplifies end-to-end communication from the sensor to the respective bus system.
FAST COMMISSIONING
Configuration is done via an intuitive web interface that allows the setting of video signals, filters and various measurement modes. In setup mode, a shadow image supports the precise alignment of the target. The system is insensitive to extraneous light and is also suitable for difficult environmental conditions, as well as for measuring transparent or reflective objects. The large measuring distance also allows flexible integration into different applications.

FORM AND POSITION TOLERANCES Concentricity is a measure of the deviation of a rotating object from its ideal axis of rotation. It is described by the difference between the maximum and minimum distance of the circumference to the reference point and gives general indications of deviations from the circular shape. Roundness describes how much the cross-section of a round measuring object deviates from an ideal circle.
360° INSPECTION OF ROTATING COMPONENTS
With the firmware update V012.000, the optoCONTROL 2700 now offers the possibility of a full 360° inspection of rotating components. Rather than only recording a measured value at certain points, the measured object is rotated and evaluated over the entire circumference. The system records various shape and position tolerances such as concentricity, roundness and ovality. The results are clearly displayed in a pie chart and can be accessed directly via the sensor’s web interface.
Concentricity is described as the difference between the maximum and minimum centre axis of the object. It indicates how far the axis deviates from the optimal centre axis. Ovality is a special shape deviation where the cross-section is not circular, but elliptical. It is defined as the difference between the maximum and minimum outer diameter in relation to the mean outer diameter.
EXTENDED APPLICATION POSSIBILITIES The new features of the sensor are used, for example, in the production of mechanical shafts or rotating components. The detection of shape deviations is particularly crucial in order to ensure function, fit and mobility. In the glass industry, this function enables a rotationally symmetrical evaluation of clear glass tubes, as the optical precision micrometer also measures transparent materials with high precision.
