Radial: A vibration measurement across the radius of a rotating shaft. It is measured in terms of Micron. The sensitivity of a radial vibration pickup (eddy probe) is 200mv DC/mill (refer to the drawings for the exact parameters).

Velocity: It is defined as the rate of change of distance travelled by the equipment. Velocity measurement is generally used for measuring the equipment body vibration. The sensitivity of a velocity pickup is 500mv DC/inch/sec (refer to the manufacturer drawings for the exact parameters).

Acceleration: It is defined as the rate of change of velocity. Acceleration measurement is generally used for measuring the equipment body vibration. The sensitivity of a velocity pickup is 100mv DC/inch/sec2 (refer to the manufacturer drawings for the exact parameters).
