In the middle of the 20th century, the manufacture of electronic weighing instruments using single or multiple weighing sensors in parallel marked the transition of weighing instruments from the past mechanical age to the electronic age. The combination of microprocessors and weighing sensors has triggered major changes in the field of weighing. With the progress of society, people have higher and...

More than 30 years ago, when electronic price-calculating scales began to be used in the private trade market, the people, metrology technical institutions and managers finally breathed a sigh of relief: violators could no longer cheat by changing the weight of the floating weight and the added weight. However, with the widespread use of electronic weighing instruments today, the cheating problem ...

The weighing sensor has the problem of temperature zero drift. The reason for this problem is that due to the asymmetry of the component parameters in the sensor bridge circuit, the temperature coefficients and linear expansion coefficients of the sensitive grid materials of the elastomer and the resistance strain gauge are different, and the length of the bridge lead wire is inconsistent. The ove...
