A sampling of magnetic technologies in the portfolio
Testing powertrains is a key task in vehicle development served by HBK.
HBK is a leader in powertrain testing through its HBM torque
transducers and other products, and also makes a number of
products that employ magnets and electromagnetics for their
functionality. Torque measurement is a key criterion for measurements
in the power train. Nearly all automobile manufacturers,
testing houses and test stand developers worldwide rely on
sensors and testing systems from HBK when analyzing their
powertrains. The non-contacting torque transducers provide the
precision needed in today's electric vehicle drive systems. The
company's HBM eDrive Testing Solution consists of hardware,
advanced software and highly precise sensors designed for ultimate
interoperability, capable of handling electrical, mechanical,
control and NVH signals simultaneously.
centrations. The paramagnetic cell consists of two nitrogen-filled
glass spheres, mounted within a magnetic field, on a rotating
suspension, with a centrally-placed mirror. Light shines on the
mirror and is reflected onto a pair of photocells.
Since oxygen is naturally paramagnetic, it is attracted to the magnetic
field, displacing the glass spheres and causing suspension
rotation, which is detected by the photocells. Current is applied
through a feedback coil present in the magnetic field to provide
sufficient torque to return the suspension to its original position.
The magnitude of this current is directly proportional to the O2
present in the sample gas mixture.
Servomex 4900 Multigas uses paramagnetic sensing to analyze
oxygen
Servomex is a pioneer developer of paramagnetic sensing technology
which is a cornerstone of its oxygen analysis products.
Used by many of our industrial, portable and multi-gas analyzers,
it delivers fast and reliable measurements of percentage O2 conwww.MagneticsMag.com
HBK
also produces a line of permanent magnet electrodynamic
shakers for vibration testing, fatigue and resonance tests, and
modal and structural analyses. Shown here is the LDS V455 permanent
magnet shaker.
