The daily maintenance and repair of the electronic weighbridge is very important. In order to extend the service life of the weighbridge, in addition to the post maintenance, the following issues should also be paid attention to at all times when using the weighbridge. Next, we will talk about the precautions in the use of the electronic weighbridge in detail.
Precautions for the use of electronic weighbridge are as follows:
1、 Select a weighbridge of appropriate range according to the weight of the weighing object
The accuracy of an electronic scale weighing 3kg and dividing value 1g is 1/3000. If it is used to weigh 2 kilograms of goods, its measurement accuracy is 1/2000. If it is used to weigh 100 grams of goods, its measurement accuracy is only 1/100.
2、 Avoid collision during the use of electronic weighbridge
Although anti-collision and limit measures have been taken in the structural design of the sensor and the electronic scale, excessive collision will damage the sensor before the limit measures take effect, which will change its electrical parameters and affect the measurement accuracy of the electronic scale.
3、 Influence of vibration and wind force symmetry accuracy
For the electronic scale weighing 15kg and dividing value of 5g, the influence of vibration and wind symmetry accuracy is small. For an electronic weighbridge weighing 200g and having a graduation value of 0.1g, vibration and wind force will make the displayed number jump.
4、 Annual inspection requirements for electronic weighbridge
The accuracy of electronic scales may change due to the impact of use, environment and device aging. Regular verification shall be carried out according to the requirements of national metrological technical regulations. Electronic scales that have not been verified or have exceeded the valid date of verification cannot be used.
5、 Influence of ambient temperature on the accuracy of symmetrical quantity
The national standard requires that the accuracy index of Class III scale should be guaranteed within the ambient temperature of 0 ℃~40 ℃. If the ambient temperature exceeds this range, the weighing accuracy may be affected.
6、 Influence of environmental humidity and acid, alkali vapor or liquid on electronic scale
The national standard requires that the accuracy index of Class III scale should be guaranteed when the ambient humidity is ≤ 90%, and it is required to avoid contacting acid, alkali vapor or fluid. For the electronic weighbridge without special treatment, the circuit parameters will change or even the circuit will be damaged if the humidity>90% and the acid, alkali vapor or fluid are attached to the circuit. For the above use environment, products with waterproof performance can be used.
The above is about the use of electronic weighbridge precautions, hope to help you.
