Large Measuring Field Profile Scanner

Laser profile measuring sensors are adaptable to suit different measurement modes

The scanCONTROL LLT30xx range of 2D/3D laser line profile sensors from Micro-Epsilon now come with two larger measuring fields.

The LLT30xx-430 and LLT30xx-600 provide measuring fields of up to 560 x 390 mm and 788 x 610 mm respectively, enabling precise profile measurements on almost all surfaces. The larger measuring fields open up greater opportunities for 2D/3D profile measurements in a wide variety of industrial applications, including automation, machine building, quality control, production and process monitoring. Due to their large measuring range, one of these new sensors can perform the same task that previously would have required several sensors.

Laser line profile scanners are among the highest performing profile sensors in terms of accuracy and measuring rate with sensors available for all common measuring ranges from 10 mm to 788 mm.

The profile scanners provide calibrated 2D profile data with up to 9.6 million points per second. The laser scanner has an integrated controller and various interfaces (including Profinet, EtherCAT and EtherNet/IP) that allow fast, easy integration into production lines and machines. With a maximum profile frequency of 10kHz and innovative exposure control, the scanners enable precise profile measurements in high speed, dynamic processes. A high resolution sensor matrix offers a resolution of 2,048 points per profile, allowing measurements of extremely fine surface/geometrical details. Due to their high accuracy, high profile frequency and versatility, the laser scanners are suitable for demanding applications, including measurement of angles, steps, gaps, distances and circles.

Predefined operating modes are available to suit each measurement task. The High Dynamic Range (HDR) mode is for optimal profile detection on difficult/inhomogeneous or dark surfaces. In HDR mode, the rows of the sensor matrix are exposed differently but simultaneously, which avoids time offsets between recordings, allowing reliable measurements of moving objects. The areas for auto-exposure can be selected individually. Other operating modes include a “High Resolution” mode for maximum precision measurements and a “High Speed” mode for ultra-fast measurements on rapidly moving objects
