At present, there are many manufacturers of electronic hanging scales at home and abroad. The forms of products are various, the prices are not the same, and there are differences in function and performance. Therefore, when selecting electronic scales, the actual needs of the unit should be referenced. The product samples provided are considered from several aspects such as measurement performance, reliability, universal interchangeability, maintainability and practicality. There are special requirements, such as explosion-proof, anti-magnetic, high temperature, insulation, etc., when ordering Explain.
1. Accuracy Selection As a measuring instrument, the first problem is accuracy. Therefore, when selecting an electronic scale, the first question is whether the accuracy of the electronic scale can meet the requirements of the actual work of the unit and whether it can meet the requirements of the state. Weighing instrument standard requirements. In general, as long as it can meet the accuracy of the unit's requirements, it is not too high to seek high accuracy, high accuracy of the electronic crane scale, its working conditions are more demanding, the price is higher.
2. Functional Selection With the popularization of electronic sensor technology and computer network management, various measurement and control devices have emerged. In order to facilitate computerized management, it is hoped that signals from various sensors will be as consistent as possible to reduce intermediate links. At present, more interface signals are used for standard RS-232 ports and 20-mA current loop signals.
The display and operation of the instrument should be as simple and straightforward as possible. The general functions of the electronic scale are: peeling (clearing), sorting accumulation (decrease), storing the vehicle number, tare, printing, communication, overload alarm, changing the receiving channel, setting the password, and the like.
3. Selection of the weighing range When selecting the weighing range, the most easily overlooked is the minimum weighing range. When the weighing scale is too large, the weighing scale can reach the national accuracy, but it can also reach the national accuracy. The relative error becomes larger. In addition, we must consider the electronic scales and cranes supporting issues, especially the electronic crane scale rings, hooks are appropriate, to carefully read the sample of the manufacturer, if necessary, can be specially proposed in advance. Of course, it is also very important not to overload the electronic crane scale.
