In highly automated production processes, length and velocity data are required
for many purposes. For instance, measurement of operational throughput delivers
essential data to control process parameters. In the manufacturing of piece
goods an automatic start and end recognition mechanism enables an
autonomous length measurement.
For a variety of materials, especially those that are hot, elastic, highly sensitive, or
dough-like, it is impossible to use tactile sensors such as odometers or tacho
rolls. The accuracy of a mechanical sensor system is also reduced by slippage,
which in practice can lead to measuring errors of 10% or more.
In both cases, non-contact optical metrology provides significant benefits. With
the Speel 3000, Zumbach offers a high-tech gauge that can be used for a wide
range of applications requiring very high accuracy at very high velocities.
The Speel 3000 is available for a measuring distance of 300mm and achieves an
accuracy of 0.05% or better. The measured length is transmitted to subsequent
electronics using an industry standard incremental interface. As an alternative, a
synchronous serial interface (SSI) is also available.
In addition, an electrical output signal compatible with common incremental
encoders is available and can be directly connected to control systems, electrical
counters, or frequency inverters.

Headlined as “Rod breakdown with
breakthrough technology” Sampsistemi
launched the RBL 1 at this year’s wire
Düsseldorf.
The RBL 1 design includes continuous,
high precision process control that
saves energy and materials.
Working with copper or aluminium
alloys, the RBL 1 rod breakdown line
will handle between 9 and 17 drafts of
1, 2 or 4 wires at speeds up to 40m per
second.
Wire elongation per draft is fully variable
and selectable.
The inlet diameter for copper wire is
from 8mm to 10mm, or 9.5mm to
12.7mm for aluminium alloy; the outlet
diameter is between 0.88mm and
5.5mm for copper, and between
1.25mm and 5.5mm for alloy.
Advantages of the RBL 1 over existing
technology are said to include:
CNC process control •
Diameter or conductivity operation •
modes
30% less energy consumption •
Quieter running, less than 80 dBA •
Oil-free, direct drive technology •
Operator-friendly supervision and •
diagnostics systems
Remote control via Internet •
connection
No preventative maintenance •
