Velocity Sensor

The vibration sensor(vibration transmitter) is one of the key components in the testing technology of vibration measurement. Its main function is to receive the mechanical quantity and convert it into a proportional electric quantity. Because it is also an electromechanical conversion device. So we sometimes call it a transducer, a vibration pickup, etc. Commonly used vibration sensors are as follows: 1. Piezoelectric resonant The piezoelectric sheet is used to receive the vibration signal, and the resonance frequency of the piezoelectric sheet is relatively high. In order to reduce the resonance frequency, it is realized by increasing the mass of the piezoelectric sheet vibrating body
