Description:
The fluid-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 impedance, high
level output can drive AC meters and recorders
without using special amplifiers, simplifying
your system.
These transducers use
a seismic mass magnet suspended by springs,
and a coil fixed to the case. The output signal
results from relative movement between the
magnet and coil when the case vibrates. The
system is fluid-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.
