Shanghai Xinzhuang Instrument Co., Ltd. develops the brand balance of Xinzhuang (LNB) brand, which is energy-saving and environmentally friendly and domestically leading. Professional manufacturing is more secure, affordable performance indicators of the electronic balance of the four performance indicators: in the gas field life when everyone is using the electronic balance, the first consideration is the stability of the balance, the sensitivity of the balance, the balance of the correctness and balance The invariance of the indication. The so-called stability refers to the stability of the balance accuracy; and the sensitivity refers to the reaction speed of the balance reading. In this respect, the electronic balance has higher sensitivity than the mechanical balance; the correctness refers to the accuracy of the reading; Refers to the stability of the balance reading, that is, the floating range of the balance reading, the smaller the floating range, the better its invariance. First, the invariance of the electronic balance indication:
The invariance of the indication value of the electronic balance refers to the degree of agreement between the measured results obtained by measuring the same object multiple times under the same conditions. For electronic balances, there is still the invariance of the balance of the balance, such as the repeatability of the electronic balance, the control of reproducibility, the control of the zero balance of the electronic balance and the error of the zero return. When the electronic balance is unloaded or loaded, the electronic balance is regulated. The electronic balance of time indicates the control of drift.
Second, the correctness of the electronic balance:
The correctness of the electronic balance is the correctness of the balance indication. It indicates the ability of the balance to be close to the true value. From the perspective of error, the correctness of the balance is the degree of systematic error reflecting the indication of the balance.
Third, the sensitivity of the electronic balance:
The sensitivity of an electronic balance is the ability of the balance to detect the amount of change in the mass of the object placed on the balance plate. The sensitivity of an electronic balance can be expressed by angular sensitivity, or line sensitivity, or indexing sensitivity, or digital (indexing) sensitivity. For electronic balances, it is mainly expressed by indexing sensitivity, or digital sensitivity. The smaller the amount of quality change that the balance can detect, the more sensitive the balance is. It is obvious that for electronic balances, the sensitivity of the balance is still one of the important performances for judging the balance.
Fourth, the stability of the electronic balance:
The stability of an electronic balance is the ability of the balance to automatically return to their initial equilibrium position after they have been disturbed. For an electronic balance, the equilibrium position is always expressed by the indication of the analog indication or the digital indication. Therefore, once the instantaneous disturbance is applied to the electronic balance, although the indication changes, the balance is eliminated after the interference is removed. If we can return to the original indication, we call the electronic balance stable. An electronic balance, the stability of the balance is the primary criterion for the balance to be used, and an electronic balance that does not have balance stability cannot be used at all.
