Laser scanners from Micro-Epsilon are among the highest performing profile sensors in the world with respect to accuracy and measuring rate. They detect, measure and evaluate profiles on different object surfaces without contact. The available models are suitable for numerous industrial applications. The integrated intelligence in their sensor head (scanCONTROL SMART) solves versatile measurement tasks. Models for the customer’s own programming are available for integrators. The scanCONTROL profile scanners do not require any external controller.

Characteristics

  • Compact size and integrated evaluation: no external controller required
  • High profile resolution for the detection of finest details
  • High profile rate for dynamic measurement tasks
  • Powerful software for parameterization and visualization
  • SDKs for integration in individual software environments
  • Proven high operational safety in the 24/7 operation over many years

One SMART scanner for all parameters

scanCONTROL laser scanners solve various measurement tasks: profile, width, height, depth, edge, bead, gap, angle, roundness and many more. With the Configuration Tools software, more than 40 measurement programs with a total of more than 90 evaluations are available. The programs are transferred to the SMART sensor, which performs the measurement, evaluation and output in standalone mode.

Intelligent SMART scanner: large range of features for numerous measurement tasks
Integrated evaluation, calculation and output of profile data
Simplifies alignment by adjusting tilted profiles
Tracking and measuring complex profiles, e.g., for inspection of adhesive beads

Profile scanners with red laser and patented Bue Laser scanners

Laser scanners from Micro-Epsilon are available with a red laser diode or with the patented Blue Laser Technology. Laser scanners with blue laser line are preferably used for profile measurements on red-hot glowing metals, as well as transparent and organic surfaces. While allowing significantly higher stability, the blue-violet laser beam does not penetrate the measuring object.
Measurement tasks involving blue laser scanners measuring on red-hot glowing measurement objects exceeding 700 °C and transparent objects such as glass and plastics are protected by patent law. The scanCONTROL laser scanners achieve excellent signal stability and thus precise measurement results on these surfaces.

Compact profile sensors

Compact size combined with low weight opens up new fields of application in profile measurement. The controllers of the scanCONTROL profile sensors being integrated in the housing simplify cabling arrangements and mechanical integration. Due to their compact size and their high profile frequency, the laser profile sensors are ideally suited to dynamic measurement tasks, e.g. in the production control or for robot mounting processes.

Various possibilities for data transmission

The sensors can be easily integrated into an existing customer software either via the available SDKs or the GigE Vision Standard which all scanCONTROL sensors meet (integration into image processing software). The sensors of the scanCONTROL SMART classes can directly transfer the measured values to the control systems using the following interfaces:

  • Ethernet (UDP or Modbus TCP)
  • RS422 (ASCII or Modbus RTU)
  • Analog, digital switching signals (with scanCONTROL Output Unit)
  • Profinet, Ethernet/IP, EtherCAT (with scanCONTROL Gateway)
