LASER SENSORS

Select components for your task from six sensor series working with three different measuring principles. Connect and evaluate data using interfaces for PLCs or IPCs or the digital controller (DCU - Digital Control Unit).

 

 

 

NON-CONTACT LASER MEASUREMENT

LAP laser sensors measure dimensions without touching the surface. Production processes can be monitored permanently, ensuring quality and reducing rejects. LAP measurement systems are flexible and easy to integrate. Having no contact with the object to be measured, you may also measure soft, sticky, hot or other sensitive surfaces. There will be no wear or tear at the sensor. There will be no traces on the surface.

Your benefits:

  • NON-CONTACT
    No contact to the object to be measured, no wear and tear on the sensor, no traces on the measured surface.
  • INDEPENDENT OF MATERIAL
    No dependance of chemical or physical material properties, colour or reflectivity.
  • FAST
    Up to 10 kHz depending on measuring principle.
  • SYSTEMATIC
    Several sensors - even of different type - may be connected for one application.
  • INLINE
    Measurement during production, also for fast processes. No need to take samples. No need to stop production.

Laser sensors reduce time for production, improve output capacity and reduce rejects.

MEASURING METHODS

LASER TRIANGULATION

A laser beam emitted from the sensor creates a visible spot on the surface of the measured object. Depending on the distance, a CCD line scan camera besides the laser ”views” this spot under varying
angles. Using this angle and the known distance of laser and camera, the Digital Signal Processor computes the distance between the sensor and the measured object.

SHADOWING METHOD

One sensor consists of emitter and receiver in separate housings. In the emitter, a laser beam hits a rotating poligon mirror. The deflected beam is converted into a beam that periodically runs through the measuring area, building a virtual light-band. In the receiver, the parallel moving beam is focused on a light-sensitive diode. Any object within the measuring field partially shadows the receiver. The time interval of shadowing precisely determines the dimension of the object.

LASER LIGHT SECTION METHOD

The sensor contains a line laser, a CCD camera and electronics for processing the camera signals. The laser projects a straight line perpendicular to the surface to be measured. The camera is fixed at a certain
angle to the laser line. Any deformation of the surface causes a deformation of the laser line from the cameras angle of view. Using the basic calibration as reference, the sensor calculates the dimensional values.
