In highly automated production
processes measurement of operational
throughput delivers essential data to
control process parameters or, as in the
manufacturing of piece goods, an
automatic start and end recognition
mechanism allows autonomous length
measurement.
When working with hot, elastic, highly
sensitive, or dough-like materials, 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
gauge that can be used for applications
that demand a high degree of accuracy
at high velocities. Speel 3000 is available
for a measuring distance of 300mm and
is said to achieve an accuracy of 0.05%
or better. The measured length is
transmitted to subsequent electronics
using an industry standard incremental
interface.
An alternative 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.
The main features of Speel 3000 include:
Speed range up to 3,000m/min •
Detection of standstill •
Detection of direction •
Start and end recognition •
Allows deviation of the measuring •
distance
Suits smooth and rough surfaces •
Long life LED illumination •
Maintenance free •

Well Gain Cable Systems Ltd has
added two products to its range – a
multi-wire drawing machines and
Electrolytic tinning plant – which have
been added with the help of Kunshan
Hongtai Machinery and Electric
Equipment Ltd.
The multi-wire drawing machine, with
continuous annealer, is an ideal
solution for customers who are
looking for efficiency, cost
effectiveness and reliability in drawing
and bunching wire strands. With a
maximum inlet wire diameter of 2mm,
the machine is able to draw bare Cu,
tinned Cu and silver plated Cu wires
down to an outlet diameter of
0.15-0.40mm at max. line speed
32m/s. Both 8-wire and 16-wire
machines are available.
The electrolytic tinning plant, complete
with water treatment system, is a
waste water free process of producing
the best quality tin plated copper
wires of wire diameter 1.0-2.6mm at
max line speed 13m/s. The tinned
wires are suitable for further wire
drawing and continuous annealing.
