Profile scanning

September 2009 Sensors & Transducers

Compact profile sensor for defined measurement tasks.

Micro-Epsilon’s range of compact profile scanners has been expanded with the new scanCONTROL 2710 sensor with extremely compact housing and integrated controller. The 2710 provides a complete solution for simple measurement tasks enabling angles, steps and positions to be recognised and tracked. The same is also possible for profiles, including adhesive beads, weld seams, grooves and gaps. After the sensor has been configured using the set-up software supplied as standard, the system runs in standalone mode and can be connected directly to a controller. Using the integrated controller, the sensor can perform data acquisition, profile calculations and measured value generation for the complete measurement field and at full resolution at 100 Hz. The compact design of the sensor makes it particularly flexible, either as a stationary measurement unit or in moving mode on, for example, a robot.

A small output module for DIN rail mounting is available enabling the conversion of data into common fieldbus systems. Using this, measurement results can be output using digital or analogue modules for evaluation or further processing.

The profile information is obtained using a static laser line projected onto the target surface. The diffusely reflected light is replicated on a sensor matrix by a high quality optical system. The sensor calculates profile data directly from the camera image and the relevant characteristic values. The characteristic values can then be transmitted via RS422 or in combination with the analogue output module or with tolerances and output as switching signals.
