SIKORA introduces diameter and length measuring devices for hose and tube

SIKORA introduces two innovative measuring devices for hose and tube – LASER PRO for diameter measuring and LM SMART for length measuring.

LASER PRO: Higher standards in diameter measurement

The LASER PRO comprises three innovative models for product dimensions from 0.1 to 51 mm. Designed based on the trusted LASER Series, the new series includes additional user advantages.

With compact and slim design, the optical components are located in protected areas. The diffraction analysis detects unavoidable, gradually occurring contamination in real time and reports it.

The diffraction analysis in combination with pulse-controlled laser diodes results in 500,000 measuring points per second per measuring axis in the entire measuring field. This results in 5,000 accurately measured values per second per measuring axis, ensuring that the values supplied are both accurate and repeatable.

Thanks to the extremely short exposure 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 single value accuracy.

The non-contact measuring technology of LASER PRO works entirely without moving parts and is therefore maintenance and wear-free. A single calibration before delivery is sufficient to guarantee precision for the lifetime of the device. The availability of the laser measuring heads is 99.8 %.

The LASER PRO offers the option of FFT analysis to detect periodically recurring variations in product parameters. This is an important tool for producing high-quality hoses and tubes and detecting irregularities during extrusion.

The measured values of the LASER PRO are displayed on the ECOCONTROL. Trend data, statistical functions and FFT analyses can also be viewed. The SET POINT control module can be used to control the diameter to the setpoint or minimum value.

LM SMART: Smart length measurement

LM SMART offers precise length measurement without contact and with extraordinary accuracy of 0.05%. With very compact design, this device can be easily integrated into existing lines.

LM SMART stands for smart length measurement.

The system is based on the market-proven laser doppler measuring method and therefore functions can be 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.
