我们知道,热电偶高温计是一种很精密的仪表,如果使用得不正确,不但容易使热电偶高温计失灵或损坏,缩短使用的寿命,并且影响了工件的质量,甚至使产品发生报废或退修造成损失,影响很大。因此,怎样正确地使用热电偶高温计,是我们工人必须学会的基本知识。现在先谈一谈使用热电偶高温计时的正确选择。选择热电偶高温计的时候,首先必须考虑到:测量温度的地方,经济效果和测量的温度范围。譬如说,用铁和康铜的热电偶来测量高温范围 We know that the thermocouple pyrometer is a very sophisticated instrument, if not used properly, not only easy to make thermocouple pyrometer failure or damage, shorten the life of the use, and the impact of the quality of the workpiece, and even scrapped the product or Retirement caused a loss, a great impact. Therefore, how to use the thermocouple pyrometer properly is the basic knowledge that our workers must learn. Now let’s talk about the correct choice of thermocouple timing. When choosing a thermocouple pyrometer, you must first consider: where the temperature is measured, the economic effect, and the temperature range of the measurement. For example, thermocouples made of iron and constantan are used to measure the high temperature range
