Description
CEC’s miniature 4-118 Vibration Transducers
are especially valuable where space is limited,
and where heavier transducers would invalidate
your results. These transducers can be used
in high temperatures, have low sensitivity to
transverse accelerations, and can be mounted in
any plane. The measurement system is simplified
because the low impedence, high level output
can drive AC meters and recorders without using
special amplifiers. These features make them
suitable for many applications on jet engines,
turbines, high speed motors, superchargers,
internal combustion engines and in test cells.
CEC’s 4-118 Vibration Transducers use a
seismic mass coil, suspended by springs,
high flux magnet is attached to the base. The
output signal results from relative movement
between the magnet and coil when the case is
in motion. This magnetically damped system
operates above its natural frequency so the
output is proportional to velocity. The gold-onsapphire bearings provide nearly friction-free
movement, extending the instrument life and
reliability. These instruments are available in two
configurations: the 4-118-0001 with an integral
cable, and the 4-118-0002 with a top connector
for a detachable cable.
