一种便携式测温仪的研制

Design of a Portable Measurement Temperature Instrumentation

介绍了利用数字式温度传感器DS18820构成的多点温度测量仪器。它具有线路简单,测量精度高的优点(在0～+45℃内,精度优于0.2℃);带有计算机接口,能够实现长时间连续测量与记录。

A multi-channel thermometer using digital temperature sensor DS1624 is presented. The thermometer's circuit is simple in construction but can achieve high accuracy of measurement,which is less than 0. 2℃ between 0℃-45℃ after simple calibration. The instrument also has an interface with computer ,longtime measrement and data logging can be realized.
