Description
CEC’s 4-130/4-137 Vibration Transducers
offer a technology breakthrough in velocity
output vibration transducer design. These
transducers use a special advanced technology
bearing system that extends their service life.
Yet, this design preserves the simplicity and
reliability that is typical of CEC’s self-generating,
low impedence vibration transducers.
t We designed the 4-130/4-137 Vibration
Transducers for turbine applications. Use them
in hot sections where high temperatures cause
problems with other instruments. They simplify
your system because low impedence, high level
output does not require special amplifiers or
low-noise cables. They have low sensitivity to
transverse accelerations, and you can mount
them in any plane. Their rugged construction
and new bearing system insure high reliability
and long service life.
These instruments are especially valuable
where space is limited. They adapt easily to
your installation because models are available
in a variety of mounting configurations and
sensitivities.
CEC 4-130/4-137 Vibration Transducers
use a seismic mass magnet that moves on
special ceramic 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 mV output is
proportional to velocity.
