用热电偶测量温度时,其引出端(即冷端)必须保持恒定的温度,否则就需要对冷端温度的变化进行电补偿。本冷端温度补偿器(图1)就是采用电的补偿方法。补偿器内有一个灵敏度高、阻值精确的精密热敏电阻。 Thermocouple temperature measurement, the terminal (the cold end) must maintain a constant temperature, or you need to change the temperature of the cold side of the electrical compensation. The cold junction temperature compensator (Figure 1) is the use of electrical compensation. Compensator has a high sensitivity, precision resistance precision thermistor.
