工频炉中钢水(或铁水)温度的测定,一般钢厂大都使用WRLB快速微型热电偶(以下简称偶头)配合进口或国产的专用仪表来检测。考虑资金和订货时间等问题,能否使用国产一般电子电位差计来做为二次仪表配合偶头测温呢?我们进行了一些初步试验,总结如下: 一、提出的问题: 我国技术标准规定的电子电位差计的全行 Industrial furnace frequency of molten steel (or molten iron) temperature measurement, the general steel mills mostly use WRLB fast micro-thermocouple (hereinafter referred to as dual) with imported or domestic special instruments to detect. Consider the funds and ordering time and other issues, whether the use of domestic general electronic potentiometer as a secondary instrument with dual temperature? We conducted some preliminary tests, summarized as follows: First, the question raised: China’s technical standards The whole line of the electronic potentiometer
