  • How Vibration sensors Work ? - InstrumentationTools

    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 element and its stationary housing (frame). Displacement sensors come in the form of a probe that threads into a hole drilled and tapped in the machine’s frame, just above the surface of a rotating shaft.
