摘要
对工业中广泛采用的热电阻和热电偶测温,根据线性时不变系统的性质,提出了一种既确保精度又简单易行的统一的测量方法。介绍了电压测量原理和电阻测量原理,指出了两种测量的统一性,说明了统一测量方法的具体实现。最后,对该方法的特点进行了分析。
According to the properties of linear time-invariant systems, a uniform method of industrial measuring of temperature, with the widely used thermal resistance and thermocouple is put forward, which can not noly ensure accuracy but also be simply realized. The principles of voltage measuring and resistance measuring are introduced, the uniformity of the two measuring methods is pointed out and the way to realize the uniform method is explained. Finally, the features of this method are analysed.
