4-102/4-103
Vibration Transducer

Description

The fluid-damped moving elementsin CEC’s 4-102 and 4-103 VibrationTransducers are free of friction, assuring long life and reliability. This frictionless design also features outstanding dynam - ic range. It can be used to measure dis - placement 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, rotat – ing machinery, in test cells and on dynamic balancing equipment. The out - put 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 amplifiers, simplifying your sys - tem.

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 han - dling. Positive hermetic sealing prevents damage to the instrument when used in severe environments.
