摘要
便携式数显测微仪在电路设计上采用了超大规模集成电路元件和液晶显示器,并用叠层电池作为电源,因而较一般测微仪体积小、功耗低,大大降低了制造成本。为测微仪在制造业、计量检测等部门的广泛应用创造了条件。本文介绍了该仪器的工作原理、测量电路的设计特点及其技术性能指标。
A portable digit display micrometer with large-scale integrated circuit and LCD in cir-cuit design has been developed. It has much smaller size and lower power consumptionthan an inductance micrometer. Its advantages help the type of micrometer to be used wide-ly in many fields. The principle, circuit design and technical index of the micrometer are presented.
