Description
The uid-damped moving elements in CEC’s
4-102 and 4-103 Vibration Transducers are free
of friction, assuring long life and reliability. This
frictionless design also features outstanding
dynamic range. It can be used to measure
displacement to 0.5 inches, with low-levels
limited only by system noise.
These transducers are used to measure
vibration in many applications, such as fans,
high speed motors, rotating machinery, in test
cells and on dynamic balancing equipment. The
output signal is proportional to velocity, often
considered the best measurement for machine
health monitoring. The low impedence, high
level output can drive AC meters and recorders
without using special ampliers, simplifying your
system.
These transducers use a seismic mass
magnet suspended by springs, and a coil xed to
the case. The output signal results from relative
movement between the magnet and coil when
the case vibrates. The system is uid-damped,
and operates above its natural frequency. The
special “C” springs, which support the mass,
withstand high transverse accelerations and
rough handling. Positive hermetic sealing
prevents damage to the instrument when used
in severe environments.
