The state-of-the-art Ludwig FL-
Mobimic SlimLine microwave mois-
ture measuring system and wire-
less Bluetooth transmission system consists
of a microwave moisture measuring probe
with integrated temperature sensor, trans-
mitting unit and a receiver module.
The system was developed in-house
by Ludwig in mid-2012, and is exclusively
distributed in the local market through Pan
Mixers South Africa (PMSA) – the largest
supplier of concrete brick, block and paving-
making machinery and technology in Africa.
Ludwig Moisture Control managing
director Manfred Ludwig was one of PMSA's
international guests at the 2013 bauma Africa
Trade Fair in September, who was on-hand at
the company's display stand to provide visi-
tors with the opportunity to obtain expert
advice and insight, while showcasing the
latest advancements that the Mobimic Slim-
Line wireless moisture measuring system
has to offer.
"As the smallest microwave moisture probe
of its kind, Mobimic SlimLine is a new
generation of wireless measuring. With
a height of just 29 mm and a diameter of
75 mm, the probe can be placed effortlessly
into confined spaces. This breakthrough in
design enables precise humidity monitoring
in process flows – an advancement that was
previously impossible with wired sensors,"
he says.
Ludwig points out that the data captured
from the probe is transmitted by an industrial
grade Bluetooth connection. "The combi-
nation of the probe with a transmitting and
receiving unit means that the Mobimic Slim-
Line can be used in stationary mixers with a
rotating mixing drum, ready-mix trucks and
moving bulk containers."
According to Ludwig, a major challenge
in moisture control is the fact that end users
are often unaware of the exact amount of
water content in the aggregates. "Accu-
rately controlling the water and moisture

content ultimately ensures energy savings,
increased productivity and an improvement
in the quality of concrete products ranging
from concrete bricks and blocks, to roof tiles,
pipes as well as delivery trucks," he adds.
PMSA marketing and sales manager
Quintin Booysen notes that the company has
been an authorised Southern Africa distrib-
utor for Ludwig for several years. "We have
worked in close collaboration with Ludwig
Moisture Control over the years to ensure
that we make the company's complete range
easily accessible to the local market, in
addition to providing all customers with the
latest product training, as well as compre-
hensive after sales and technical support."
Although the Mobimic SlimLine wire-
less moisture measuring system is a niche
product, Ludwig is optimistic that the
company will obtain measurable market
share in Africa, as a result of the continued
expansion of the concrete pre-cast and
ready-mix industry both locally and in
Southern Africa. "Expansion of these indus-
tries has prompted an increased demand
for better quality concrete and greater
control during concrete manufacture as
well as delivery in the ready-mix sector. The
Mobimic SlimLine system has a proven track
record in international markets for effec-
tively achieving these objectives, and I have
full confidence that similar results will be
realised in Africa too."
Booysen states that PMSA plans to focus
on its 2014 strategic imperatives, which
include monthly industry-specific open
training sessions held onsite at the PMSA
showroom and sales facility.
