Abstract:
The electronic vibration meters/analyzers are used to measure and analyzer the intensity of vibration in turbo
machinery, generating stations, ships, aircraft, manufacturing plants, water, and sewerage heavy electrical
equipments. Vibrations canbe due to unbalance of rotating parts , misalignments or external force. For each of
these measurements various types of transducers are used. In general, vibration measurements are made to study
the response of a body or structure. Study the vibratory environment surrounding a vibratory source viz., floor
monitor and control a system such as in maintaining accelerations at a desired level etc. The vibration
meter/analyzer consists of a transducer, signal conditioner and a display system. The transducer converts the
mechanical vibration into an electrical signal. The signal conditioner converts the transducer output into a suitable
electrical output. The output divices may either be digital display/analog panel meter, graphic recorder,
oscilloscope or a magnetic tape recorder. In general application LVDT or piezo-electric transducers are used for
vibration measurement.
