Basic Introduction To Vibration Meters

Vibration meter is an instrument used to directly indicate the peak value, peak-to-peak value, average value or root mean square value of vibration quantities such as displacement, velocity, acceleration and acceleration derivative. The main parts of this instrument are integral and differential circuit, amplifier circuit, voltage detector and meter. The integral and differential circuit is used to complete the integral and differential operations between the above-mentioned vibration quantities. Generally, integral and differential operational amplifiers can be used, and low-pass filters and high-pass filters can be used to complete the integral and differential operations. However, when calculating with such instruments, attention should be paid to their application frequency range. Vibration meters can only allow people to obtain the total intensity of vibration (vibration level), but can not obtain other information, so the scope of use is limited.
