Oscillating meter

A vibrator is an instrument that directly indicates the peak, peak-to-peak, average, or rms value of vibrations such as displacement, velocity, acceleration, and acceleration derivatives. The main parts of this instrument are, integral differential circuits, amplifiers, voltage detectors and heads. The integral differential circuit is used to complete the above-mentioned vibration between the integral and differential operation, generally can be used integral, differential operational amplifier, can also be used low-pass filter, high-pass filter to complete the integral and differential operation. However, the use of this instrument should be calculated when they pay attention to their application frequency range. The vibrator can only give people the total strength (vibration level) of the vibration, and can not obtain other information, and therefore use a limited range.
The method of measuring the vibration requires that it does not have any effect on the measured vibration process during the measurement. Therefore, it is desirable to measure the vibration by a non-contact method if it is possible to leave a point of the object to be a stationary reference point The But as for walking
There is a case where a stationary point is not used as a reference, and an inertial vibrator is often applied to the object to be measured, and the vibration of the object is measured indirectly from the movement of the vibrator. In fact, most of the vibration measurement is carried out by means of an inertial vibrator with a vibrator. In the case where the reference point can be found, there are many such vibrations. Therefore, the vibrator is generally referred to as An inertial vibrator with a vibrator.
