Since 1984, MeCalc has grown into a company that
produces some of the world’s best data acquisition systems. Read on for a quick breakdown of some of
MeCalc’s successes over the years.
IMPERIAL COLLEGE LONDON
Founder and President of MeCalc, Dr. Gilmer
Klintworth, completes his PhD. Despite his mechanical engineering background, he designs and builds an
electronic system for a servo hydraulic testing machine which measures and controls threshold fatigue
crack growth tests.
UNIVERSITY OF PRETORIA
Professor Gilmer Klintworth lectures structural
mechanics at the University of Pretoria. He leads a team of 25 post-graduate and consulting engineers
which develops electronics and software capable of reproducing forces that structures would be subjected
to in real life, under laboratory conditions.
MeCalc: Mechanical Engineering Calculations
MeCalc is founded. The new company develops electronics and
software for Carl Schenck (now Instron) and impresses their new customer with a solution which allows
data sampling rates more than 2.5 times faster, with twice the number of acquisition channels than Carl
Schenck’s existing systems (ITFC). Based on HP1000 mini-computers with their own vector instrumentation
set, MeCalc removes the need for a separate array coprocessor.
MECALC BRANCHES OUT: New applications
A controllable unstable platform to test the
stabilization capability of a turret.
Simulation of multidimensional forces around a
helicopter’s rotor head.
Numerous motor vehicle suspension tests.
ESTABLISHING LONGEVITY OF INVESTMENT: MODACS
MODACS, MeCalc’s first mobile data acquisition system, is
developed. Compact, modular, with its own Ethernet interface and vibration-isolated hard disc, it is
designed with the future in mind. Created with a solid foundation from which all successive systems
grow, these systems incorporate VMEbus and VRTx real time operating systems and already contain a large
variety of signal conditioning channels including Wheatstone Bridge modules.
The first MODACS customer uses the system to measure the stresses
in the C pillar of a motor vehicle during a 1600 km test, showcasing the long-term monitoring capability
of these systems.
MECALC AND BMW
Numerous data analysis and test simulation systems are sold to BMW
in Munich, including a system to test their first electronic damper controlled (EDC) shock absorbers.
BMW is impressed by the team and coins the term “The MeCalc Team”.
MeCalc designs and builds a system that simulates the thermal
environment around a satellite, measuring 1000 thermocouples and 100 PT100 temperature sensors while
controlling 100 heaters.
Measurement of 384 accelerometers and control of 8 shakers for a
ground vibration testing facility for aircraft.
BMW calls the MeCalc-developed software which works
with our MODACS systems, “Mausy” (an endearing term borrowed from the German “mausi” which means
MECALC AND MÜLLER-BBM
BMW introduces MeCalc to Müller-BBM
and a strong, more than 20-years long hardware-software partnership begins. The collaboration heralds
the introduction of a more compact mobile data acquisition system with 3- and 6-slot chassis variants
containing up to 32 and 80 ICP® channels respectively. The new systems are about 5 times
smaller than the units they replace, with the same channel density.
A NEW ICONIC DESIGN
New mainframes are machined from aluminium and built with
innovative heat-dissipating fins, able to dissipate heat when mounted horizontally. The design becomes
iconic and remains largely unchanged with successive models.
This provides a stable foundation from which to apply progressive,
partial upgrades due to the system’s innate modularity. With the focus on longevity of investment, a
standards-based concept ensures a stable foundation for new innovation.
UPGRADE TO PAK MKII
Müller-BBM starts to exclusively sell MeCalc
hardware worldwide. Between 2006 and 2010, customers are encouraged to “upgrade” their systems from
their Sony EX, Heim and VXI systems to the new PAK MKII hardware designed, developed and manufactured by
MeCalc. The strong partnership between MeCalc and Müller-BBM continues and is bolstered by their close
The PAK MKII design wins the IF Design 2006 award.
UPGRADE TO G2
G2 infrastructure is introduced, offering
advanced signal integrity and lower power as well as superior processing throughput, higher data rates
and additional optional features such as WLAN and SSD. A more efficient system power supply on the new
controller board series, along with a more efficient power supply on the signal conditioning boards for
each Module, results in improved noise floor for all measurements. Improved and new Modules are also
introduced in the G2 upgrade, increasing signal conditioning variety and modularity.
EVEN HIGHER CHANNEL DENSITY
Channel density is improved once again with 192
ICP® channels in a single mainframe.
MECALC TECHNOLOGIES, USA.
The launch of MeCalc Technologies Inc in the USA, with offices
in Atlanta, Georgia.
Calibration (ISO/IEC 17025)
For over 20 years our products have been sold through our partner Müller-BBM VibroAkustik Systeme,
predominantly to clients in Europe and Asia. Eager to introduce our new range of products to different
markets, MeCalc Technologies was formed in the United States to service the North American market.
With our new QuantusSeries range now assembled – and soon to also be
designed – in the United States, we carry on the tradition of fearlessly breaking new ground to advance
The launch of QuantusSeries
sees a new era for MeCalc and its
products. Inspired by the desire to create open and accessible solutions, MeCalc releases a new range of
products that allow the user to configure a personalized measurement setup, collection and analysis
workflow. Forward thinking solutions remain the focus, with the incorporation of new PCIe, PoE and PTP
IEEE 1588-2008 standards.
The strength of our standards-based design allows the same system
to successfully incorporate changes in technology while maintaining a sustainable foundation. With 1500
QuantusSeries channels in the market already, QuantusSeries carries on the tradition of fearlessly
breaking new ground to advance technological developments.
