摘要
针对目前低温环境与低温测量领域中,低温测量仪表价格昂贵、体积庞大、测温范围窄等问题,设计出了一种基于ADuC834单片机为核心的高精度低温测量仪表。实验结果表明该仪表工作稳定可靠,而且测量精度高,测温范围宽,成本低,体积小,测量方便,便携性好,具有很高的性价比。
In the field of low - temperature measurement now, the current high - precision instrumerits have the disadvantage of high price, large size, narrow measurement - range etc. This paper designs a high -precision measuring meter based on ADuC834. The results show that the meter is reliable and practicable. Besides, because of the high -precision, small size, wide measurement -range and low price, it has a good ratio of performance to price.
