[China Aluminum Network] Many users often use electronic scales, but what are the quality indicators for electronic scales? Perhaps few people know that the three important quality indicators of electronic scales are accuracy, stability and reliability. Many floor loaders must consider the fatigue life and stability of loadometers during the design and production process. Long-term stability includes three factors: aging, fatigue, and the environment.
“Environmental factors†are the effects of simulating time as a long-term temperature change, and verifying their environmental suitability through reliability tests including life tests and environmental tests.
When electronic scales are used to compare harsh environmental conditions, they are required to have strong environmental adaptability, high reliability and low failure rate. The environmental adaptability of electronic scales is mainly:
1. Weather resistance factors: effects of temperature, humidity, pressure, etc.
2. Electromagnetic factors: electromagnetic field or electromagnetic radiation interference.
3. Special medium factors: tolerance to influences such as salt water, chemical corrosive gas, and nuclear radiation.
For example, the electronic scale weighing sensor applied for prototype testing requires testing and measuring the wear resistance, aging, and susceptibility to interference of the part to ensure that the measurement performance of the electronic scale sensor is not affected by the electromagnetic field, electrostatic force, vibration and climate. Conditions, mechanical wear and other interference effects.
It is concluded that the environment-resistant condition design and the protection and sealing technology are important links in the design and manufacture of electronic scale sensors, and are fundamental guarantees for the sensor to withstand the objective environment and the influence of the inductive environment on the stable and reliable work. If the protection and sealing are bad, the moisture in the air in the resistance strain gauge and the adhesive will make the adhesive layer expand and plasticize, causing a sharp drop in insulation resistance, adhesive strength and rigidity, causing zero drift and irregular output, and even electronics. Scale sensor failure. Therefore, environmental conditions must be designed to improve the environmental adaptability of electronic scales.
