杠杆式力标准机与称重传感器试验问题研究

摘要

Weighing sensor is the core device In the modern electronic weighing~ The sensor performance test methods and means, especially the means test equipment is the necessary condition for ensuring performance. Traditional lever type force standard machine is a kind of important means test equipment, its work efficiency (load), one-time investment in equipment (cost) and the accuracy of the status quo, seriously affect the users' confidence. Experimental studies show that, application of new technology and advanced technology and the concept of new type lever type force standard machine, the three performance indicators and any other form of force standard machine, has better effect, can fully meet the weighing sensor load characteristics, creep property, temperature and humidity properties testing required.%称重传感器在现代电子衡器中是核心器件，对传感器进行性能试验的方法和手段，尤其是试验设备手段是保证其性能的必要条件。传统杠杆式力标准机作为一种重要的试验设备手段，一直以来，它的工作效率（加载时间）、设备一次性投入（造价）和准确度等现状，严重影响了使用者的信心。实验研究表明，应用了新技术和先进技术与理念的新型杠杆式力标准机，上述三项性能指标与其它任何形式的力标准机相比，具有更好的效果，完全可以满足称重传感器的负荷特性、蠕变特性、温湿度特性等性能试验的需要。
