Thermal imaging reduces downtime and improves safety
A thermal imaging service designed to reduce plant breakdowns, minimise costly
repairs, optimise the production process and improve safety in the workplace.
Magnet’s newly established
division – Magnet Electrical
Projects – offers a critical service
to all industries in the electrical
and instrumentation sectors,
including solutions for hazardous
environments.
“Although the Magnet Group
has provided a service to support
electrical equipment, industrial
instrumentation and automation
throughout the country for over
20 years, increased demand for
expert solutions has led to the
establishment of Magnet’s new
formalised division,” says Johan
Roets, training and site inspection
manager, Magnet Electrical
Projects. “Four specialist solutions
sectors of this division include
panels, automation, metering and
onsite services.
“Magnet’s onsite services
encompass power quality analysis,
electrical compliance auditing and
power factor correction, as well as
onsite electrical installations and
the retrofit of air circuit breakers.
“Magnet’s thermal imaging
service has been designed
to reduce plant breakdowns,
minimise costly repairs, optimise
the production process and
improve safety in the workplace.
By detecting irregularities that are
usually invisible to the naked eye,
thermal imaging – which is one
of the most valuable diagnostic
tools for industrial applications -
allows corrective action to be taken
before costly system failures or fires
occur.”
Magnet’s thermal imaging
service forms part of a condition
monitoring programme to
determine when and where
maintenance is needed in electrical
and mechanical installations and

suitable for measurements in public networks, installation category CAT IV.
components. By using reliable,
non invasive thermal imaging
instruments, which are able to
scan and visualise the temperature
distribution of entire surfaces
of machinery and electrical
equipment quickly and accurately,
preventative action is taken in the
event of a fault. What’s important
for production plants, is Magnet is
able to perform inspections, even
when systems are under load.
This specialist service
encompasses the provision of
a full image of each situation
and accurate temperature data
during the monitoring of high
voltage equipment, low voltage
cabinets, motors, pumps and high
temperature equipment, as well
the detection of insulation losses.
A small electrical problem can
have far reaching consequences.
As the efficiency of the electrical
grid becomes low, more energy
is used generating heat. If left
unchecked, this heat can rise to
the point where connections
start to melt and this can result in a
devastating fire.
Magnet Electrical Projects is
able to identify and locate a fault
before costly problems occur and
also advise exactly what needs
to be fixed. This thermal imaging
service - which extends from the
examination of a fuse box, to the
inspection of a large industrial
installation - ensures cost savings,
reduced downtime and improved
safety standards.

Compact chilled mirror hygrometer gives high accuracy for
reliable control of sintering processes
The new S8000RS chilledmirror
hygrometer offers an
accuracy of ±0.1°C, with a wide
measurement range of -90 to
+20°C dew point, making it the
ideal choice for moisture control
in a range of metallurgical
processes, including sintering.
Sintering is a process where
powdered metals are bonded
together to form light and strong
products, from filters to machine
parts. Because the powdered
metal is not fully melted, the
temperatures involved are
relatively low – around 600°C –
but careful control of moisture is
essential to ensure the finished
quality.
Because the raw material
is powdered metal, moisture
present in the furnace could cause
clumping or, as the moisture
evaporates in the heat, large holes
being created in the finished
product. To avoid this, accurate
control and measurement of
moisture is vital.
For sintering carried out 600°C,
maintaining a constant dew point
of -60°C in the furnace is necessary
and the gas is sampled at several
points in the process.
A fast-responding moisture
analyzer is essential so that action
may be taken quickly if moisture
levels rise above acceptable limits.
Michell’s S8000RS uses the
fundamental chilled mirror
technique to measure moisture,
which ensures long-term accuracy
to ±0.1°C dew point as well as
reliability and a fast response.
The measurement range of -80
to+20°C dp is ideal to ensure
consistent monitoring at -60°C
with confidence in the accuracy.
The S8000RS is the smallest
hygrometer on the market
which is able to reliably reach
dew points of -80°C. This small
size is possible because it does
not require any external cooling,
which makes it well-suited to
metallurgical applications where
its small footprint makes it easy
to install in an air conditioned
instrumentation cabinet.
