CALIX series sensors allow for thickness measurement from one single sensor housing. They can be used instead of applications consisting of displacement sensors and measuring frames without the need for temperature control and frequent recalibration. This is due to the fact that the alignment of the measuring beams is optimised during production and then the sensors are sealed within the housing. One of the main advantages of this, is that complicated alignment procedures are not required after the sensor has been commissioned and errors related to alignment can't occur.

Calix Principle

CALIX sensors can easily be integrated into production lines, reaching over objects to be measured from the side without the need for O-frames or bridges. They are available with different measuring ranges and limb lengths. The limb length limits the distance of the measuring spot from the objects edge.
CALIX series sensors provide extremely precise results on virtually all materials, independent of limb length and measuring range. They automatically adapt to changing colours and surfaces. Even measurements on shiny aluminium, non-vulcanised black rubber, and soft or sticky materials are possible.

Calix stress free design

  • Material - with very low impact by temperature changes
  • Construction - very rigid with no internal stresses and can withstand processing line environments. I.e., Protection from dirt, steam, etc.
  • Result Dtot = constant
Absolute Measurement
  • No alloy compensation needed
  • No influence of surface properties
Factory Calibrated
  • At constant ambient temperature field calibration usually not necessary (ΔT < 5°C)
  • But if so, takes only a few seconds
  • Best calibration using rotating disk
  • Ethernet interface
  • Class 2 Lasers (1mW)
  • No NRC requirements
  • No X-ray or Gamma radiation
  • No high voltage electronics
