A lot of research goes into reducing
the overall height, even though
17mm is state of the art at present.
Nevertheless, even a high-speed
WIM sensor 11mm high might
be feasible. n

engineers also have a hard job to
find the best technology for their
creations. It is difficult to combine
a low profile with robustness, light
weight with a large surface area,
wireless functionality and a backlight
with long operation time or a
large temperature range with
certified accuracy.
This difficult task in the
background is what makes the
difference. Haenni Instruments
develops and manufactures mobile
wheel load scales, making use of value
engineering. The Swiss manufacturer
invests a lot to create not only longlasting
products, but also enduring
technology. The reliable hydraulic
measuring system has been used over
45 years with the first mechanical
scale WL 100 until the last developed
static scale WL 108, without the need
for big improvements. By keeping the
measurement technology the same,
the enhancement that is possible on
peripherals is faster.
All Haenni scales weigh less than
20kg and are maximum 17mm high.
OIML, NIST and EU certified, they
operate in a wide temperature scale
ranging from -20 to +60°C. Their

durability means only minimum
maintenance is required, and
most components and the scales
themselves are manufactured in
Switzerland, where each detail is
carefully controlled.
The biggest challenge is to reach
in dynamic modus what is already
achieved in static modus. It might
