(Summary description)There are always various ways of expressing the sensitivity and accuracy of balancing machines. So what is the difference between the two? The following introduces the content of the difference between the sensitivity and accuracy of the balancing machine. Sensitivity refers to the response of the method to the unit concentration or the degree of change in the unit quantity of the substance to be tested. It can be described by the ratio of instrument response or other indicators to the concentration or quantity of the substance to be measured. It is the closeness between the survey value and the actual value. When each physical quantity is represented by a numerical value, it is necessary to establish a specification. The norms are generally based on people's understanding and understanding of the physical quantities to be measured, and it is necessary to consider whether the norms are easy to imitate. Perhaps the measurement process is easy to operate, and sensitivity and accuracy are also used in the field of balancing machines, which is of great significance to balancing machines. There are many ways to express the sensitivity and accuracy of the balancing machine. The accuracy of a general instrument is represented by the commonly used indication value or the percentage of full scale of the amplitude error, and the phase error is generally used. However, with regard to the balancing machine, if the correction is made according to the unbalance indication of the above accuracy indication, and the allowable residual unbalance of the rotor is within a certain limit, for the rotor with a large initial unbalance, the fault seems to be too strict. Balancing the smaller rotor, the fault seems to be lax. In addition, even if there is a certain amplitude and phase error, if the number of corrections is increased, the residual imbalance will gradually decrease within a certain limit, but after reaching the certain limit, it cannot be smaller.
