1. Problems with unreasonable installation and debugging Faults: According to the survey, when a factory installed and commissioned two program-controlled hopper scales, it was found that the two scales interfered with each other, and the control system sometimes failed to work according to the specified procedure, and often malfunctioned;
Reason: The connection mode of the two scales is connected by four-wire system. Since we are located in the northern high-cold area and the temperature difference between winter and summer is relatively large, we analyze and conclude that the error is due to the change of the wire resistance with the temperature change. We will have four wires. After the system was changed to the six-wire system, the problem was solved. 2. The shortage of electronic components for electronic scales Electronic scales are the most widely used electronic scales. Installation and commissioning have been very experienced. However, there has been an unprecedented phenomenon, phenomenon: the installation of the standard time, found that the weight displayed by the display meter is suddenly small, but the number of meters displayed is also related to the placement of the weight, it can not be normal calibration. After inspection, the sensor's connection line is correct, and the display instrument and the mechanical part have no failure;
Cause: The internal wiring of the sensor is incorrect. Since the positive and negative poles of the internal lead of the bridge voltage or signal are reversed when the sensor is packaged at the factory, the above fault occurs when the connector is connected with the normal color mark during the installation, and the connection is changed. After re-calibration, the above phenomenon was ruled out.
This article will simply introduce you to the failure analysis of electronic scales. If you want to learn more about electronic scales, you can contact us directly. Thank you for your support!

With the continuous development of industrialization in our country, the value of the use of electronic scales has become increasingly higher and more and more, so how to better play their role is more and more important. . However, whether it is the use of electronic scales or newly installed electronic scales for many years, there will be some failures, which will cause them to not be used normally, and it will be a difficult time for people to bring them into trouble. Therefore, we have problems with electronic scales. Under simple planning, the overall situation is mainly two kinds of common faults and special faults. So no matter what type of fault is, it is nothing more than the following problems that are often caused by several major aspects such as weighing indicator, load cell, power supply, connection line and mechanical force transmission mechanism.
