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
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 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 “darling”).
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
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 development
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,
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 technological developments.
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
VISION: SAME GOAL NEW TERRITORIES
For over 35 years, our measurement platform was built with the focus on providing our customers with 100% data confidence. This is done by having incredibly stable, precise and high-quality data acquisition. Because we haven’t been focused on the analysis of software, we are uniquely positioned to become a new hardware platform for both OEM partners who want to write software compatible with our instrumentation and those who want to integrate with our hardware from more open (MATLAB / LabVIEW / Python) software environments. HP was this for technology in the 1980s. We believe MeCalc is this for the data acquisition market today.
