Description
The friction-free moving elements in CEC’s
4-131 Vibration Transducers assure long life and
reliability. Designed for industrial applications
on fixed turbines, you can use this instrument
in turbine hot sections where high temperatures
cause problems with other transducers. The
system is simplified due to the low impedence,
high level output that can drive AC meters,
recorders, and control electronics without using
special amplifiers.
The frictionless design also allows
measurement of extremely low vibration levels,
critical when monitoring precision balanced
turbine systems. The low level is limited only by
system noise.
These transducers use a seismic mass
magnet suspended by springs and a coil
attached to the case. The output signal results
from relative movement between the magnet
and coil when the case vibrates. The air damped
system operates above its natural frequency, so
the output signal is proportional to velocity. The
sealed case prevents damage to the instrument
when used in difficult environments.
