3-axis two-in-one
For the first time, operators of multi-
purpose lines can make use of a sector
gauge head with integrated 3-axis
diameter measurement function for
measuring ranges of up to 100mm.
With this technology Sikora reacts to
customer demands for multi-function
measurement systems for different product
applications in one production line.
The ‘two-in-one’ gauge head is based on
a newly developed sandwich principle.
For this application the Laser 2100 S/R
is combined with the Laser 2100 T.
According to requirements the sector
or diameter measuring function can be
chosen. The measuring principle of the
Laser 2100 S/R is based on a combination
of three laser diodes as light sources with
a CCD-line sensor in one plane.
The height of stretched sector cables,
which can be solid or stranded, is defined
from the position of the edges that define
the object. Even if the product turns up to
±15˚ the height is accurately determined.
The Laser 2100 S/R is appropriate for
the measurement of sector conductors
with a cross section of A max=750mm2
(for 120°-sectors) and A
max
= 500mm2 (for
90°-sectors).
The outer diameter and ovality of round
cables is also calculated with an optical
measuring principle. With the three laser
light sources in three planes and CCD-line
sensors, the outer diameter is calculated
directly from the shadow image with the
help of advanced software. The gauge
head is suitable for round cables from
1mm to 100mm.

New thermal spraying wire
The obvious solution to steel corrosion is to galvanise but, in extreme conditions, a
galvanised structure can have a short life and it is very difficult to re-galvanise at a later
stage. Thermal spraying of pure aluminium or pure zinc is also recognised as a good
way of preventing corrosion with aluminium having a longer life but the concern with
aluminium is that it tends to passivate in mildly corrosive environments.
A new alloy wire for thermal spraying has been developed to bridge the gap between
zinc and aluminium. CJ Wiretech Ltd, in conjunction with the BAC Group, is offering an
aluminium-zinc-indium wire for arc or flame spraying. This alloy has been used before
as solid sacrificial anodes in marine environments but it is now freely available as a wire
from the BAC Group. AlZnIn is basically an aluminium alloy where the added zinc and
indium behave as ‘activators’ to prevent passivation. The material is therefore suitable
for thermal spraying directly onto steel and will act as a sacrificial protector in all
corrosive environments where salt is a concern. This means that any onshore or offshore
steelwork can be protected for 25 years or more against the ravages of corrosion.
An added advantage is that AlZnIn alloys have been used for many years for the
sacrificial protection of steel rebars embedded in reinforced concrete. The alloy is
sprayed onto the surface of the concrete and electrical connections are made between
the sprayed layer and the rebars, thus giving a protection as if there was a direct contact
between the two metals. The idea is not new but in the past it has been difficult to
source wires for the process; they are now available from CJ Wiretech Ltd.
