Myth: Charge mode
transducers have superior performance characteristics and are better
suited for use as a reference standard. Busted! For
decades, ICP accelerometers have had superior noise susceptibility
and signal impedance, and are, in fact, better suited for reference
standard applications, as well as most general purpose uses.
Currently, charge mode transducers are required primarily for making
measurements at elevated
temperatures. |

Shock &
Vibration Support for Discovery Channel's
Mythbusters |
|
 The Modal Shop and PCB Piezotronics, recently
supplied The Discovery Channel's popular science series Mythbusters
with vibration test equipment for the Dumpster Diving episode.
In this episode, the show hosts Jamie and Adam instrument Buster the
Dummy with PCB model 356A02 triaxial ICP® piezoelectric
accelerometers to measure impact shock levels induced by a "typical"
4 story jump into a dumpster filled with trash, determine the
probability for survival and bust the myth commonly seen in getaway
scenes of action movies where the action hero hops out after the
fall and escapes from the villain. Follow this link for some
screen shots of the PCB triax in
action...

The Modal
Shop is celebrating its 20th Anniversary in 2010. We
hope that you've enjoyed our newsletter again this month, as well as
its educational content over the last few years. No where like
the sensing calibration fields are certainty and reliability more
important. We're here to serve you with all your dynamic sensor and
calibration needs.
