偶衡式溫度計由热电阻和比率計二者組成。热电阻:是偶衡式溫度計配合使用的感溫元件,由于热电阻(或称电阻溫度計)工作端受溫度的影响,它的阻值将随温度高低的变化而变化着,其輸出端接到二次仪表(比率計)。比率計:因它偏轉角度与电流比有关,故又称流比計。由图1很明显看出,它与其他类型磁电式仪表不同,它在测量系統中有
Even-scale thermometer by the thermal resistance and the ratio between the two components. Thermal resistance: is a thermocouple thermocouple with the use of temperature sensing element, the thermal resistance (or resistance thermometer) working end affected by temperature, its resistance will vary with the temperature changes, the output connected to Secondary instrument (ratio meter). Ratio meter: Because of its deflection angle and the current ratio, it is also known as flow meter. It is clear from Figure 1 that it differs from other types of magnetoelectric meters in that it has
