Advantages and disadvantages of resistance strain type load cell

The weighing range of the resistance strain type weighing sensor is tens of grams to thousands of tons, and the measuring accuracy is 1/1000~1/10000. Because of its simple structure, convenient installation, and reliable operation, it is used by most electronic weighing instruments.

The advantages of resistance strain sensor are high accuracy, wide measurement range, long life, simple structure, good frequency response characteristics, can work under harsh conditions, and is easy to realize miniaturization, integration and variety.

The disadvantage of resistance strain type load cell is that it has mechanical hysteresis, creep, zero drift and strain limit. It has large nonlinearity and weak output signal for large strain, but it can be improved by some measures.
