18 Extrusion International 4/2024 INDUSTRY NEWS Smart Length Measurement of Hoses and Tubes  The LM SMART stands for smart length measurement, and it expands SIKORA‘s product range with an innovative length measur- ing device. The system measures lengths without contact and with extraordinary accuracy of 0.05 %. Compared to conventional contact- based solutions, there is no slippage or wear. Once the device has been configured, no further calibration is required. The LM SMART measures accurately and reliably over time. Length measuring devices are used to ensure that the required hose or tube length is accurate. Short or excess length leads to yield losses. If the production length is re- duced by just 0.1 %, the LM SMART length measuring device pays for it - self in just a few months. The LM SMART is based on the market-proven laser doppler mea- suring method and therefore func - tions largely independent of the color, surface quality and diameter of the product. Two laser beams are used to direct light onto the passing product surface. The beams overlap and create a stripe pattern on the object, from which the speed and thus the product length traveled over time is precisely determined. The LM SMART offers precise length measurement and ensures that the required product length is maintained. Thanks to its very com- pact design, this device can be eas - ily integrated into existing lines. No slippage, no maintenance and only a single calibration. This impressive system ensures smooth, continuous measurement independent of the material, which allows for use on many different products. The long service life also ensures maximum availability of the LM SMART. New Standards in Diameter Measurement SIKORA’s new LASER PRO sets even higher standards in the field of hose and tube diameter measure - ment. Designed based on the trusted LASER Series, which has been used in numerous extrusion lines worldwide for several decades, the new series includes additional user advantages. The LASER PRO comprises three in - novative models for product dimen - sions from 0.1 to 51 mm. The diffraction analysis in com - bination with pulse-controlled la- ser diodes results in an impressive 500,000 measuring points per sec- ond per measuring axis in the en - tire measuring field. This results in 5,000 accurately measured values per second per measuring axis. This ensures that the values supplied are both accurate and repeatable. Thanks to the extremely short ex- posure time of less than 1/1,000,000 seconds, the individual precisely measured values per second per axis are captured with maximum image sharpness. This ensures absolute measuring accuracy, even at high line speeds with product vibrations. Each individually measured value achieves an extraordinarily high sin - gle value accuracy. The non-contact measuring tech- nology of the LASER PRO works entirely without moving parts and is therefore maintenance and wear- The LM SMART complements SIKORA's product range with a smart length measuring device The measured values of the LM SMART can be displayed on the ECOCONTROL or directly on the system control unit With the LASER PRO, SIKORA launches a device series on the market that measures the diameter of hoses and tubes with the highest measuring accuracy
