1测温仪表的选用传统的回转窑测温系统一般是由热电偶(热电阻)、热电偶温度变送器(热电阻温度变送器)、补偿导线和显示仪表组成。这种仪表系统精确度和稳定性很好,但仪表造价较高,维修不方便,相对于数显仪表读数也不方便。因此,智能数显控制仪在回转窑测温系统逐渐得到了较为广 A selection of temperature measuring instruments The traditional rotary kiln temperature measurement system is generally composed of thermocouple (RTD), thermocouple temperature transmitter (RTD temperature transmitter), compensation wire and display instrument. This instrument system accuracy and stability is good, but the instrument cost is higher, maintenance inconvenient, relative to the digital instrument reading is not convenient. Therefore, intelligent digital controller in the rotary kiln temperature measurement system has been more widely
