CALIX flagship on course for success

The enhanced precision of the CALIX laser measuring system by LAP saves expensive raw materials

The newest generation of the CALIX measuring system by LAP measures the thickness of sheets more efficiently than ever. The advantages over radiometric measuring systems are clearer than ever. However, the most attractive feature remains the astounding precision and measuring consistency in daily production. In addition, expensive radiation protection measures are necessary with this nearly service-free technology. Given the significant temperature stability and mechanical decoupling, CALIX enables virtually drift-free measurement.

The maximized precision and measuring consistency of measuring equipment helps save semifinished goods and expensive raw materials. It also improves quality and allows it to be reproducible. Traditionally, there have been two types of measuring procedures for measuring the thickness of sheets: Radiometric measuring systems (x-ray and isotope), and contacting measuring equipment. Technologies based on ultrasound or fluidized beds have not gained general acceptance.

More precise than radiometric systems

Laser measuring systems were introduced in the 1980s and 1990s. They can measure a whole series of properties including thickness. However, laser measuring devices only became a reliable alternative to radiometric or contact measurement upon the introduction of laser triangulation. Comprehensive studies have revealed that laser systems frequently perform better than traditional systems.

Contact-free measurement independent of materials and temperature
As a pioneer in laser measurement, LAP from Lüneburg has been producing and developing a laser-based systems for more than 25 years for contact-free measurement - from sensors to turn-key measuring systems. In contrast to radiometric measuring systems, the laser systems of LAP are independent of the properties of the materials. For example, CALIX measures the thickness of shiny and hot sheet metal as well as black matte sheets of rubber.

The material properties do not have to be adapted to the laser-based CALIX measuring system. This is in comparison to radiometric measurement of thickness where calibration is frequently required. Calibration expertise such as for different qualities of steel is unnecessary with the CALIX system. This saves personnel costs. In addition, the time-consuming recording of material data in tables is not required. This prevents errors from incorrectly entered material data. There is also no time and effort for radiation protection with LAP systems.

CALIX is compact, service-free and optimally aligned

An additional argument for CALIX is the minimal amount of installation effort. The laser measuring system is light and compact and can therefore quickly replace conventional measuring systems, for example the context of modernization. CALIX sensors are almost service-free and are optimally aligned in the factory.

Michael Witte, Product Manager for CALIX at LAP, about the newest CALIX generation: "CALIX is our flagship. We have been able to render its outstanding product features such as contact-free thickness measurement and material and temperature independence more robust than ever. In addition, CALIX is the only system in the market that permit virtually drift-free measurement."

Precise measurement reduces scrap
The CALIX system measures the thickness of continuous sheets in-line with a precision of ± 1 micrometer and more. "Our measuring systems prevent dimensional deviations during production," notes Witte. In measuring differences in thickness, for example, CALIX systems perform up to 4,000 precise measurements per second independent of the temperature and material with an extremely high repetitive accuracy of the sensor starting at ± 0.35 µm."

The new laser systems are suitable for measuring the thickness of continuous sheets up to a thickness of 28 mm (with a measuring range of 30 mm). With a maximum measuring depth of 1,020 mm, they can be placed on the side of the path of transport without needing a bridge construction.

CALIX sensors use digital signal processors (DSP). The signals are digital from measurement to output and are therefore insensitive to disturbing influences. The thickness noise of radiometric systems or source noise of isotope systems does not occur.  The system graphically and numerically portrays the measured values online and immediately reports measurements lying outside of the tolerances. Scrap is minimized which has led to significant savings for LAP numerous customers.
