The new gapCONTROL laser scanner from Micro Epsilon has been developed specifically for non-contact gap measurement. The sensor is based on laser light section technology, though it makes use of a totally new evaluation procedure. Known as gapCONTROL 2711, three different models can measure different types of gaps up to 300 mm deep and 50 mm wide. The sensor supports the user in welding processes, measuring flushness, overlaps, proximity and height discrepancies, etc. The data is then used for the robot control or quality assurance purposes. All the electronic features are integrated in the sensor, making it quick and easy to mount. Using the gapCONTROL setup software tool, the sensor can be quickly prepared for its measurement task. Depending on the nature of the gap, only those parameters are provided that are necessary, in order to keep the settings as simple as possible. The software can also be tested fully without a scanner. The sensor's standard outputs are FireWire, Ethernet or RS422. Other output formats are available via the Output Unit.
