All-round capability for non-contact inline dimensional measurement

have no affect on the measurement. The combination of 1-6 laser/camera modules allows the measurement of virtually all shapes, achieving an optimal measurement result with the smallest possible number of laser/camera modules. The Odac Trio system is based on Zumbach’s vast experience, gained over many years of design and manufacture of optical diameter gauges. This measuring head features 3 integrated measurement axes.

Zumbach Switzerland, provides a complete line of measuring and monitoring instruments. Typical applications of these systems are hot rolling mills for wire steel rod, profiles and seamless pipes, welded pipe production, test stands (NDT), and cold processes, like peeling, grinding, straightening, and polishing. This technology is geared towards closer tolerances (½, ¼ DIN), zero faults, 100 per cent quality control, higher productivity, faster startup, less downtime and manpower. Zumbach provides three systems groups: Steelmaster, Profilemaster ® and Odac ® Trio. Steelmaster is a non-contact laser measuring system range for hot and cold, inline and applications in rolling mills. Profilemaster provides profile and shape measuring systems for hot and cold, inline and offline applications, while Odac Trio are 3-axis laser diameter gauges. Steelmaster gauges and systems are based on the latest technology. Almost 300 units are in operation in hot rolling and similar processes. They are backed up by many thousands of Odac scanners, operating in cold processes. The Steelmaster processor is the ‘brain’ of the system. It processes the measuring data, communicates with the plant network and provides the operator with self-explanatory displays and key data. The process transparency is dramatically improved, especially if multiple measuring heads are installed. Electronic,

The machine can be used with oscillating gauges for round and non-round products (flats, squares hexagons etc). This system has up to 6 measuring axes for seamless 360° coverage, with measurement independent of twist. There are no blind zones, with cross section computation and oscillating or static

operation. The version with static gauges is especially suited to round products. This compact system has up to 6 fixed axes, no moving parts and an extremely fast measuring rate, with short measuring distances. Steelmaster gauges offer decisive advantages for easy integration, dependable operation and data processing and display. They include hi-tech laser scanners with high accuracy, up to 6,000 measurements (1,000 per scanner), compact industrial PC, and highly developed software. In addition, the

Conventional 2 axis instruments with laser or CCD can only provide approximate values for a minimum OD and maximum OD and ovality. The mean value (X+Y/2) is influenced by the orientation of the product ovality within the measuring field. Advantages of the ultra-compact Odac Trio include 3 synchronized measurement axes on 1 single plane, and reliable detection of out-of-round condition, regardless of the orientation of the product ovality. The device detects any deviation from roundness of oval and out-of-round with polygonal shape (multi-lobe), with highly accurate yields regardless of the orientation of the product ovality. The Trio computes accurate values of circumference and cross section, which is important when mixing the products of tube and hose. The technology also offers increased measurement accuracy and reliability, and integrated fault detector with 3 times higher detection certainty and sensitivity (than 2 axis models).

Steelmaster comes with sophisticated mechanics and protection system, and close to zero maintenance. Designed for any requirement, the modular Profilemaster system provides accurate inline profile measurement using the ‘light section’ principle and machine vision. One or up to six laser/camera modules measure the cross-section of the moving profile.

A powerful PC based processor adds together the partial pictures of the cameras made up of straight lines and radii to yield the momentary cross-section of the profile. All relevant dimensions such as width, height, angle and radii are combined to form the full cross-sectional picture. The nominal values for the profile can be directly imported from the CAD construction (as a DXF file), which allows easy and problem free programming. Changes in speed and twist within normal limits
