What is the method of weightless weighing to obtain flow and the principle of measurement accuracy

Author: Smartweigh–Multihead Weighter

During the whole application process, the multihead weigher will reasonably use its weighing and feeding company as all its weighing, and will sample the net weight signal according to the symmetry that continues to appear on its in-vehicle dashboard throughout the application process, In this way, the conversion rate of the multihead weigher per unit time can be reasonably measured, and then the acceleration flow can be measured. For the acquisition of this kind of flow, the multihead weigher is very important, because it is the basis for the accurate measurement and detection of the product. The internal ant colony algorithm of the instrument panel in the vehicle of this kind of industrial equipment is used to carry out control and calculation close to the flow. Output regulation signal to control soft starter, etc. The acquisition of this kind of traffic is very important, and it is also the basis for the accurate measurement and detection of the multihead weigher.

In the whole process of the actual application of the multihead weigher, the product can be seen from the basic concept that the product is not easily damaged by the change of its net weight from one side of the scale to the other side of the scale. This is only for the measurement and verification of the net weight. The reason for the deviation, and the traditional dynamic measurement detection method is also a significant advantage. The multihead weigher has a strong ability to transport raw materials, and its measurement and detection volume is high-precision during application. It carries out accurate measurement for the silo during the whole process of work. It is actually carried out in the data format. The reason for the deviation in weight is to measure the flow rate. The reason for the deviation of the multihead weigher and the error caused by the flow calibration value also depends on the accurate measurement time of the net weight of the product is more than ten minutes, and it is not easy to suffer from sensor zero drift and temperature changes during application, and then Can obtain higher measurement and detection accuracy.

The system without net weight scale does not need steel, and its stainless steel plate will be selected in the whole process of application, so that it can be used in sites with weak geographical environment specifications, mechanical equipment has durability, less maintenance frequency, and is not afraid of high temperature and other characteristics, worry about high temperature raw materials. The basic concept of multihead weigher is followed by FC based on the PID feedback ant colony algorithm, to carry out control and calculation of the total flow close to the target, and output adjustment signals to control the feeder controller, such as a soft starter. Problems to be paid attention to when designing a multihead weigher, the factors that damage the accuracy: the multihead weigher takes into account the characteristics of the data format scale and the visual data scale. Therefore, in the drawing software planning scheme, the requirements are: 1. The appropriate range of the delivery rate, in Generally, in actual work, it refers to the range of 60% to 70% of the rated current of the conveying capacity.

If you choose to communicate and communicate speed regulation, the frequency of ground stress should preferably be in the middle of 35-40Hz. That way, the range of the adjustment range can be ensured. Also because the transmission speed is too low, the reliability of the system is weak.

The measurement range of the sensor should be moderate, according to the calculation formula. The basic concept of multihead weigher In other words, the detection range of the sensor is also 60%~70% of the detection range, and the signal conversion range is wide, which is very beneficial to improve the accuracy. 3. The design of the mechanical structure scheme should ensure that the fluidity of the raw materials is excellent. In addition, it is necessary to ensure that the feeding time is short, and the feeding should not be too small. Generally, it is required to feed once every 5-10 minutes.

The transmission system that cooperates with each other should ensure stable operation and excellent line shape.
