Electronic crane scale is a special product, it is generally used with hoisting machinery, widely used in steel, metallurgy, coal, machinery, chemical and other industries, so their priority is safety, are generally required to achieve the rated weigh four to six times the safety of the load, especially used in metallurgical industry of insulation electronic crane scale! So shackles, weight sensors, hooks, and weighing connectors need to be selected from quality brand suppliers with redundant size allowance! Electronic crane scale is used in trade settlement, so I need very high precision (level III for the precision of the scale, in recent years, domestic customers require more than the accuracy of balance of level III), and the use of electronic hook scale occasion is same time shaking, vibration, and reverse the bad environment, some electronic crane scale even for stability in the process of mobile reading, is a process of dynamic weighing, want do need from several aspects, customers can also from these aspects to compare the pros and cons of electronic hook scale!
First of all, the weighing sensor is an important part of the electronic hook scale! The important parts of the weight sensor are the metal material used in the elastomer and its heat treatment, the form and size of the structure, the resistance strain gauge and glue used, and the manufacturing process. The elastomer of the weight sensor of the high quality electronic hook scale generally adopts the alloy structural steel of 40CrNiMoA (40 Crni mo A), which has good hardenability in heat treatment and fatigue resistance.
The second is the structure of the electronic hook scale, shackles, weighing sensors, hooks composed of hanging pendant swing freedom. The electronic hook scale with excellent performance usually has a track of 90° between shackle swing and hook swing, similar to the cross coupling driven by automobile, which can effectively absorb the energy of shaking, vibration and twisting during lifting and weighing, so as to improve the harsh working environment. Cheap electronic hook scales do not have this structure.
Finally after ensure the weighing sensor output realistic signals, is relatively important electronic circuit board and SCM procedures, in order to deal with in the process of using electronic crane scale, shaking and twisting vibration, good microcontroller program need to set up a number of mathematical application model to identify the weighing signal and interference signal screening, digital filtering, indices such as response rate adjustment, so as to guarantee the stability of electronic hook scale quickly grab weighing data, and guarantee good repeatability.
