CALIX series is the first family of LAP sensors for differential thickness measurement in one housing. They replace measuring frames, that need time-consuming recalibration and temperature control due to their temperature characteristics. The alignment of measuring beams is optimised during production at LAP. CALIX sensors don‘t need complicated adjustments of opposing sensors in the measurement frame. Errors related to alignment won‘t occur. 

For wide material, measuring tracks in the middle of a roller table or for large movement ranges during traversing measurement LAP off ers CALIX XL. The measuring depth of more than 1 meter allows for enough movement in most applications, that may be realized without a stationary, massive O-frame.

LAP also designs rail constructions for your application, as well automated ones for traversing measurements as ones with manual handling for moving them out of the transport way and back in for measuring.
