TEMPERATURE MEASUREMENT ROUND UP
Endress+Hauser South Africa has designed
and built a portable calibration hub, the first
of its kind, bringing its world-class process
calibration technology to Mutanda Mine
SARL (Mumi mine), an open-pit copper
mine located within a remote area of the
Democratic Republic of Congo (DRC).
Ghislain Mbayo, process control super-
intendent at Mumi, says that the project
began when the mine urgently required a
state-of-the art calibration and maintenance
facility to ensure quality and production
uptime and reduce unplanned shutdowns
and cost. However, it did not want to build
a facility due to the time it took to obtain
building rights.
“Because we are situated so remotely,
there had been no daily assistance with
proper calibration at our process plant,
something that we knew posed a great
threat to our production target,” adds
Mbayo.
T h e m i n e c omm i s s i o n e d t h e
Endress+Hauser South African office to
design, build and supply its calibration
and maintenance needs in one 3 m x 6 m
container.
The completed container had to fulfil
the mine’s objectives to obtain accurate
measurements via advanced calibration
and verification technology, conduct train-
ing on specific instruments and calibration
methods, and enable both testing and fault
finding.
“The best process plants must be able to
identify their own performance strengths
and weaknesses, then take that information
and learn from those mistakes,” explains
Mbayo. “We decided that if we wanted to
learn from a workstation, the best solution
was a container workstation.”
Wouter Carstens, head of the service
department at Endress+Hauser SouthAfrica
led the project. He points out that the entire
solution was customised to fit the purpose,
as set out by the customer.The internal and
external layout of the container was key to
fulfilling all requirements. “This means that
everything – from the grids to the desks,
plugpoints, windows and door was fitted”,”
highlights Carstens. “The container we
chose is also resistant to corrosion. This,
together with its lowmaintenance and high
quality, makes it an ideal product in the often
harsh African territory and climate.”
