Why We Use Vibrometer?

A vibration meter is used in manufacturing for machine condition monitoring, product testing and quality assurance. Many machine maintenance technicians use vibration meter devices in tandem with sound level meters to analyze frequency.

What is the purpose of vibrometer?

A vibrometer is generally a two beam laser interferometer that measures the frequency (or phase) difference between an internal reference beam and a test beam. The most common type of laser in an LDV is the helium–neon laser, although laser diodes, fiber lasers, and Nd:YAG lasers are also used.

How does a vibrometer work?

How does a barometer work? Simply put, a barometer acts like a balance that 'balances' the weight of the atmosphere (or air around you) against the weight of a mercury column. If the air pressure is high, the mercury will rise. At low air pressure, the mercury goes down.
