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, weighing sensors, hooks and weighing connectors need to choose high-quality brand suppliers, and with redundant size margin! 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 dynamic weighing process, want to do a good job from several aspects, customers can also compare the advantages and disadvantages of electronic hook scale from these aspects!

First of all, the weighing sensor is an important part of electronic hook scale! The metal material used by the elastomer and its heat treatment, the form and size of the structure, the resistance strain gauge and glue used and the production process are important for the weighing sensor. The elastomer of weighing sensor of high quality electronic hook scale generally uses 40CrNiMoA (40 Chromium-nickel-molybdenum A) alloy structure steel, heat treatment hardenability is good, so the fatigue resistance is very good.

The second is the structure of electronic hook scale, shackle, weighing sensor, hook composed of hanging pendant swing degree of freedom. Electronic hook scale with excellent performance, usually shackle swing and hook swing track is 90°, similar to the car driven cross coupling, can effectively absorb the shaking, vibration and twisting energy generated during lifting and weighing, so as to improve the bad 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, In this way, the electronic hook scale can grasp the weighing data quickly and stably, and ensure good repeatability.
