A new measuring head is available from Zumbach, offering
highly accurate outside diameter measurements up to 500mm.
Systems in static or oscillating configuration are available, for
hot or cold processes, with up to six axes.
Zumbach has developed the ODAC® 550 HLF for large
diameters, widths, heights and diagonals. This technology is
said to eliminate previous problems and disadvantages of large
product systems. At the heart of the development is a new
optical system for collimation and scanning, generating an
absolutely parallel (telecentric) measuring field and supplying
1,000 calibrated measurements per second. Accurate
measurements are generated, regardless of product position in
the measuring field. It also makes possible large emitter-receiver
separations of 2m or more.
ODAC® 550 HLF features include:
Large 550mm measuring field without dead zone •
Absolute parallel scanning •
Accuracy and stability, typically within 0.01mm •
No position error •
Very large emitter-receiver separation possible •
1,000 calibrated measurements (CSS) without averaging •
High scanning speed, over 1,020m/s •
These features open many new possibilities and allow for tighter
product specifications for hot rolling, cold rolling, forming and
welding applications as well as for other processes in difficult
environments.
