Description:
CEC designed
the 4-128 Vibration Transducer for turbine
applications. You can use them in turbine
hot sections where high temperatures can cause
problems with other transducers. The system
is simplified due to the low impedance, high
level output that can drive AC meters, recorders,
and control electronics without using special
amplifiers. They have low sensitivity to transverse
accelerations, and you can mount them in any
plane.
These instruments are especially
valuable where space is limited, and where
heavier transducers would invalidate test
results. They adapt easily to your installation
because models are available in a variety
of mounting configurations, connector orientations
and sensitivities. Rugged construction and
design simplicity insure high reliability
and long service life. The 4-128 is factory
repairable.
CEC’s 4-128 Vibration
Transducers use a seismic magnet that moves
on gold bearings. A coil is attached to the
case, and movement between the magnet and
coil produces the output signal when the case
vibrates. This air damped system operates
above its natural frequency so the output
is proportional to velocity.
