Background

The laboratory centrifuge has wide application field, is generally used in various laboratories such as hospital laboratories, scientific research institutions laboratories, food and drug inspection laboratories, food sanitation laboratories and the like, and has the rotating speed of not more than 30000r/min. The rotating speed of the laboratory centrifuge is an important technical parameter, the centrifugal force is in direct proportion to the rotating speed of the laboratory centrifuge, and the suspension or emulsion cannot be thoroughly separated if the rotating speed does not meet the specified requirement. During the course of an assay, the same substance may be separated using different laboratory centrifuges, and different conclusions may be drawn, which seriously affect the assay result. The centrifuge requires periodic rotational speed measurements.

The rotating speed of the centrifuge is measured by sticking 1 piece of reflective paper on a measured rotating shaft and processing a light reflection signal obtained by a sensor. 1 piece of reflection paper is pasted on the measured rotating shaft, the light source of the reflection type photoelectric rotating speed sensor can emit light to the measured rotating shaft, and the light emitted by the light source is incident on the measured rotating shaft through the lens and the semi-permeable membrane.

Generally, detection personnel need to hold a velocimeter for a period of time to detect the transparent cavity of the upper cover of the centrifuge. The disadvantage of this method is that the hand shake of the operator affects the speed measurement and needs to be measured again, and meanwhile, a unit needing to be measured often has multiple centrifuges, and the operator maintains such a working situation for a long time, which is easy to cause occupational diseases.
