Improvement measures for the application of electronic floor scales

1. Enhance the rationality of the use of electronic floor scales

Electronic floor scale usage is reasonable will directly affect the role of play, for use in the process, the first thing to pay attention to the determination of index values of the weighing sensor, weighing sensor calibration dividing value shall be equal to the actual degree: e = d, and sensor maximum degree should be greater than scale calibration dividing value: p e n, the minimum static load weighing sensor output value DR shall meet the following conditions: R = 1, DR e/N 0.5 or less. When DR is unknown, the condition should be satisfied: n LC≥Max/e. The minimum calibration score of a weighing sensor
If R=1, V min≤e In practical use, n LC≥n is mostly ignored, which is the most important problem.

When the calibration index value of the scale exceeds the maximum calibration index value of the sensor, it fundamentally violates the sensor error distribution principle of the scale. Theoretically, the system is unstable. According to the current usage of the market scale, in the verification of multiple sensors, the verification degree of most scales is between 3000 and 6000, which causes fewer quality problems in the use process. The larger the scale is, the more frequently problems will occur.

2. Technical improvement of weighing personnel

Weighing personnel should pay attention to the control of equipment, maintenance, maintenance work, to ensure the normal operation of the electronic floor scale. Technical personnel should first understand the electronic floor scale equipment operation, skilled read the electronic floor scale manual, understand the use of electronic floor scale notes, to prevent improper operation of the electronic floor scale caused adverse impact, resulting in measurement results error, affect the development of work. Weighing technicians should not only master the basic operation mode and matters needing attention of the electronic measuring scale, but also carry out daily maintenance and maintenance of the electronic weighing scale.

Daily cleaning and maintenance of the electronic weighing scale will prevent problems in the use process, resulting in inaccurate measurement results. Weighing personnel and instrument maintenance personnel to pass a special technical  training, master certain technology before work. In a word, improving the technology of floor scales can make the service life of electronic floor scales longer and the measurement results more accurate.

3. Select stable verification method.

In the verification of large weighing electronic floor scale, a good verification method should be selected to reasonably define the pressure level and medium accurate level, and control the error within a reasonable range, so as to promote the smooth verification. Then, pre-check test should be carried out first, and a suitable weight truck should be selected to be weighed continuously for about 10 times to ensure the randomness of the weighing position. On this basis, symmetrical measurement value should be observed and analyzed. If the measurement value has good repeatability, it can be verified.

4. On this basis, partial load detection should be carried out.

From the actual situation, partial load detection has certain complexity and particularity. Therefore, in the process of partial load detection, multiple possible influencing factors should be fully considered to improve the rigor of inspectors, and effective partial load detection should be carried out on this basis. Taking a forklift truck as an example, we made a systematic analysis based on the actual capacity of the forklift truck. On this basis, we ensured that the center of gravity of the forklift truck was basically aligned with the position of bearing emphasis, and repeated test and adjustment were carried out continuously.
