Vibrometer -10

Vibrometer -10

Purpose:

Vibromonitoring of industrial equipment, vibrodiagnostic measurements and rotor balancing at their seats.

Recording of vibration signals for electronic data processing and analysis, en-route measurement.







Constitution and principle of operation:

Vibrometer is made as a light-weight device with accumulator and mains supply.

Gage sensors include ICP-chopper and rotation frequency sensor (optoelectronic, vortex-current or magnetic).

Registration and signal recording from sensors is made in the form of vibration acceleration time sequence. To calculate vibration parameters the methods of numerical processing and spectral signal analysis are used.

The device allows one to measure the volume units levels of vibration displacement, vibration velocity and vibration acceleration, harmonic components of vibration spectrum, rotation frequency, phase angle, excess, peak factor. A function is available to determine the rotor's rotational velocity by chopper signal without rotational velocity sensor.

The measurement range of vibration parameters is set by the user.

The calculation functions of the excess and peak factor are used for diagnostics of rolling and sliding bearings and instability of mechanical vibrations.

Light-emitting stroboscope for visual control of mechanical vibrations and phase angles is completed with vibrometer.

Connection of gage sensors with a cable 100 m long is admitted.

Recording functions of vibration signals in the form of time sequences for subsequent electronic data processing and analysis are realized. Signal recording under en-route-off-route measurement in arbitrary points of equipment at the user's option is provided.
