工农业生产工艺过程中,温度常常是最重要的被监测参数之一。例如农业上经常需要一种便携式万用测温计来测量土壤、饲料、仓库和养畜房空气、干燥和保藏谷粒等的温度。为此,研制了一种具有外附式温度变换器(传感器的便携式电子测温计)。这种测温计利用锗晶体管作为传感器,尺寸小, During industrial and agricultural production processes, temperature is often one of the most important monitored parameters. For example, a portable multi-purpose thermometer is often required in agriculture to measure the temperature of soils, fodder, storage and livestock farms, drying and preserving grains and the like. To this end, developed with an attached temperature transducer (sensor portable electronic thermometer). This thermometer uses germanium transistor as a sensor, small size,
