What is a Vibration meter?

A vibrometer (English: Vibration meter) is a device that measures the magnitude of vibration of an object to be measured. The magnitude of vibration is generally expressed on three scales: displacement, velocity, and acceleration. It is important to select which parameter to measure depending on the type of vibration you want to measure and the item you want to evaluate. When measuring acceleration, it is sometimes called an accelerometer.

Application of Vibration meter

Vibrometers are widely used in fields such as research and development, production sites, and environmental protection. In the field of research and development, for example, the vibration characteristics of parts are measured at the product development stage to prevent resonance, breakage, and abnormal noise. At the production site, as one method of product shipment inspection, for example, the quality of the product is judged by measuring the vibration of the engine. In addition, in order to prevent damage due to transportation, vibration during transportation is reproduced with a testing machine to improve packaging. In addition, for turbine generators, etc., we monitor vibration during operation to detect failures at an early stage. In the field of environment, vibration measurement is indispensable for solving the pollution problem caused by vibration generated from factories and construction works. The effect of vibration on the human body is determined by measuring the vibration level, which represents the ratio to the reference acceleration. The vibration level is defined in ISO and JIS, and is also used to judge the ride quality of automobiles and railroad vehicles. It is also used to measure the vibration of an earthquake and issue an alarm, and to measure the vibration waveform of an earthquake to evaluate the seismic / vibration-proof structure of a building.
