An eddy current sensor is a displacement measurement sensor it can be considered as the improved version of an inductive proximity sensor. This sensor is...
Vibration meters use PNP transistors instead of NPN because they are inexpensive. The PNP transistors used by the circuits needed a negative bias voltage rather...
Introduction Sensors used to measure vibration come in three basic types: displacement, velocity, and acceleration. Displacement sensors measure changes in distance between a machine’s rotating...
Definition Basically, vibration is oscillating motion of a particle or body about a fixed reference point. Such motion may be simple harmonic (sinusoidal) or complex...
The instruments which are used to measure the displacement, velocity or acceleration of vibrating body are called vibration measuring instruments. What is machine vibration? Machine...
AccelerometerAccelerometers are a piezo-electronic (crystal) device. A pre- loaded crystal is charged with current and as the crystal is compressed or de-compressed by vibration an...
Measurement Type Only measurements of the same type can be compared. Bearing Cap or Case Vibration cannot be directly compared to Shaft Relative or Shaft...
