摘要
介绍了手持式数字皮辊加压力测试仪的原理、元器件参数选择方法及测试头应变梁的设计依据．该仪器主要由３１２位液晶显示器、双积分型模数转换器、高灵敏度半导体应变片等组成，具有外形小、精度高、耗电省、使用方便等特点．
A portable digital roller weighing tester was developed.It consists of a 3 bit liquid crystal display,a double integral A/D convertor,and a sensitive semi conductor sensor.It is small in size,high in accuracy,low in power consumption and easy to use.The principle and design of the tester is introduced in this paper.
