热电偶是一种普遍使用的测温传感器。由于它结构简单,几何尺寸很小,测量精度高,测试又很方便,所以在机床行业中常用于机床温度场、热源、切削温度的测定。 对于精密机床试验来说,其测温精度有一定要求。因此,在利用热电偶(如铜-康铜热电偶)进行测温时,首先要对热电偶进行标定,
Thermocouple is a commonly used temperature sensor. Because of its simple structure, small geometrical dimensions, high measuring accuracy and convenient testing, it is commonly used in the machine tool industry to measure the temperature field, heat source and cutting temperature. For precision machine test, the temperature measurement accuracy has certain requirements. Therefore, the use of thermocouples (such as copper - Constantan thermocouple) for temperature measurement, the first thermocouple to be calibrated,
