半导体的电阻数值与温度之间的灵敏关系早就发现了。近来由于应用上的广泛需要而发展了利用这一些性质的多种器件——热敏电阻。 热敏电阻最通常的用途是测量温度。它可以用于各种一般温度计所不能解决的技术问题上。如微弱的热流,遥远的测量和控制,人体的内部——例如胃中的测温,车轴的发热。完全可以设想广泛地把热敏电阻用于堆积如山的仓库内部与高额丰产地的穗丛之中进行测温。
The sensitive relationship between the resistance value of the semiconductor and the temperature has long been discovered. Recently, due to the wide application of the need to develop the use of these properties of a variety of devices - thermistors. The most common use of thermistors is to measure temperature. It can be used for a variety of general thermometer can not solve the technical problems. Such as weak heat flow, remote measurement and control, the interior of the body - such as the temperature in the stomach, the heat of the axle. It is entirely conceivable to use the thermistor extensively in the interior of a mountainous warehouse and in the ear of high-yielding fields for temperature measurement.
