The fan is the common auxiliary machinery equipment in fields such as energy chemical industry, and the most easy trouble that takes place of this type of equipment is the vibration, and the measurement to the fan vibration is all based on hand-held type vibration tester and professional vibration analysis appearance at present. The handheld vibration tester is convenient to use, can quickly and directly measure the vibration of the fan, but the measured value is discontinuous, and the frequency and the phase of the vibration cannot be measured, so that the handheld vibration tester is only suitable for daily inspection of equipment.
For a fan with abnormal vibration, a professional vibration measuring and analyzing device is required, and a currently used vibration analyzer comprises a speed/acceleration sensor, an analyzer body, a key phase and a part of connecting wires.

To the vibration measurement of fan, photoelectric sensor's reflection of light strip often pastes on fan shaft coupling department or fan blade, but because the surface is coarse or there is the greasy dirt to paste insecurely, when the fan rotates, leads to reflection of light strip to drop very easily under the centrifugal force effect, and photoelectric sensor receives external light source's interference easily, when solar illumination or illumination are too strong, often can not receive rotational speed signal.
