一、概述力传感器是否能满足人们期望的要求,这不仅决定于其是否有所要求的计量性能,还取决于使用过程中其计量性能的可信赖程度。也就是说,在分析和评价力传感器时,精确度固然是一项重要的技术指标,但不是唯一的技术指标。在实际使用中,特别是当力传感器用于生产过程控制系统时,精确度的复现性如何?环境适应性如何?安全性如何?故障维修率如何?实用性如何?一句话,也就是说力传感器的可靠性如何?这是另一项重要的技术指标。大量的测试数据表明,力传感器的非线性、重复性、滞后等项计量性能指标已接近国际同类产品的水平,但是在可靠性方面仍有很大差距,主要表现在早期失效率过高。
First, an overview of the force sensor can meet the expectations of people, not only depends on whether it has the required measurement performance, but also depends on the use of its measurement of the reliability of the performance. In other words, while analyzing and evaluating force sensors, accuracy is certainly an important technical indicator, but not the only technical indicator. In practice, especially when the force sensor is used in the production of process control systems, what is the reproducibility of the accuracy? How about the environmental suitability? How about the safety? How about the serviceability of the failure? How practicability? In a word, What is the reliability of the force sensor? This is another important technical indicator. A large number of test data show that the force sensor nonlinearity, repeatability, hysteresis and other measurement performance indicators are close to the level of similar products in the world, but there is still a great gap in reliability, mainly in the early failure rate is too high.
