半导体点温计是用热敏电阻作为它的感测元件,由于半导体点温计灵敏度高,能快速测量微小物体温度等优点,已经在实验室和工业生产中得到广泛使用。但它存在着互换性差,维修不便等缺点,这主要是由于热敏电阻的“温度—电阻”特性各不相同,而且呈严重的非线性所引起的。由于这个原因,半导体点温计一般都制成台式或携带式。鉴于我们在实验室和试验车间中测温需要,我们利用热敏电阻的优点,采用简易的方法,
Semiconductor thermometer thermistor as its sensing element, due to the high sensitivity semiconductor thermometer can quickly measure the temperature of small objects, etc., has been widely used in laboratories and industrial production. But it has the shortcomings of poor compatibility and inconvenient maintenance. This is mainly due to the fact that the “temperature-resistance” characteristics of the thermistor are different and cause serious non-linearity. For this reason, the semiconductor thermometer is generally made of desktop or portable. In view of the need for temperature measurement in laboratories and test plants, we take advantage of the advantages of thermistors in a simple way,
