Isotron ® accelerometers<br />
Isotron ® accelerometers feature an integral electronic impedance<br />
converter, eliminating the need for an external charge amplifier.<br />
They can drive long cables with minimal distortion and noise pick-up.<br />
The Isotron ® electronics are compatible with the industry standard<br />
IEPE current sources that are built into many FFT analyzers and<br />
data acquisition systems. (Current sources and amplifiers are also<br />
available from <strong>Endevco</strong>). These accelerometers offer the ultimate in<br />
testing convenience and are available with a wide selection of ranges,<br />
sizes and shapes. Special accelerometers, pioneered by <strong>Endevco</strong>,<br />
include lightweight versions with a 30 kHz bandwidth, high sensitivity<br />
units for seismic measurements, and the lowest noise accelerometers<br />
for measuring whole body motion.<br />
Helicopter monitoring<br />
<strong>Endevco</strong> has played a major role since the initial<br />
development and incorporation of HUMS (Health<br />
and Usage Monitoring Systems). Applications such<br />
as rotor track and balance require a high-output,<br />
low-noise accelerometer. Gearbox bearings and<br />
shaft monitoring may require an accelerometer<br />
with high resonance frequency and linear response<br />
to 10 kHz and above. Our design experience<br />
through proven flight usage has made the Isotron ®<br />
series a favorite choice for HUMS applications.<br />
