In fact, the kind of vibration sensor using a rich, according to their different works can be divided into eddy current vibration sensors, vibration sensors inductive, capacitive vibration sensors, piezoelectric vibration sensors and vibration resistance strain sensors.
Eddy current vibration sensor: eddy current type vibration sensor of the eddy current effect is the principle of the vibration sensor, which is a non-contact sensor. Eddy vibration sensor by changing the distance between the tip and the sensor on the measured object, the object is measured vibration parameters. Eddy vibration sensors are used to measure the vibration displacement.
