Extrusion International 1-2020

31 Extrusion International 1/2020 Tube and hose manufacturers are searching for fast, precise and cost-effective ways to measure and record tubular samples in the laboratory Conventional contact measuring equipment such as calipers, micrometers or dial gauges offer no satisfactory solution. The small, sometimes soft products aredeformedby the con- tact pressure, which has a negative effect on the acquisition of the measured value. In addition, contact measurement methods and their associated results are heavily dependent on the personsmaking them. Different handling of themea- suring tools as well as dexterity often result in significant variations in results. With ZUMBACH’s GaugePro it is now possible to perform themeasurement of tubular samples completely contactless. With state-of-the-art ultrasonic technology, the wall thick- ness, inside diameter and outside diameter are measured instantly. In addition, the ovality and eccentricity can be de- termined. The inserted sample is measured immediately at four fixed measuring points. Due to the rotation function, the mea- surement can be extended to eight measuring points. This increases the coverage around the product and all variations in wall thickness become visible. An automatic self-calibration ensures that the measured val- ues are accurately and reliably recorded even under chang- ing environmental conditions. All measured values are displayed clearly in the large user in- terface. Several measured tube samples can be summarised in a common statistic. The logging of the measurement re- sults is thus fast, easy and reliable. GaugePro can make the measurement results available in different ways. In addition to a conventional printout of the measurement results, they can also be stored in a CSV file, or written directly to a customer-side MySQL database via the ODBC interface. Currently two GaugePro variants are available. GaugePro 8 covers a diameter range from2.5mm to 8mm. GaugePro 22 canmeasure tube samples from 6.8 mm to 22 mm. Using GaugePro makes off-line measurement of tubular samples significantly faster, more accurate and more reli- able. A handy and efficient tool has emerged that consider- ably increases the productivity of every quality assurance and supports modern digitization. ZUMBACH Electronic AG P.O.
