在使用DDZ型表仪的过程中,往往遇到计算两个待测量的商和显示出来的实际问题,这种除法仪就能完成上述任务。与常规方法相比,节省了一台乘除单元(有时用了乘除单元,甚至还不能正常工作),从而提高了检测系统的可靠性。由于这种除法仪相当于一台普通的电位差计,因而有利于维修工作的顺利进行。 1974年3月已在鞍钢11号高炉采用了这种除法仪,用于测量高炉的透气性。三年多的运行结果表明,它已成为高炉操作中的一台重要仪表,其示值稳定并便于维修,深受现场欢迎。为解决应用这种除法仪时所遇到的各 In the process of using the DDZ type meter, it is often encountered to calculate the quotient of two to be measured and display the actual problem, this divider can accomplish the above tasks. Compared with the conventional method, save a multiplication and removal unit (sometimes multiply and remove units, or even not work), thereby increasing the reliability of the detection system. Because this divider is equivalent to an ordinary potentiometer, which is conducive to the smooth progress of maintenance work. March 1974 In Anshan Iron and Steel 11 blast furnace used this divider instrument, used to measure the permeability of the blast furnace. The result of more than three years of operation shows that it has become an important instrument in operation of the blast furnace. Its indication value is stable and easy to maintain, which is deeply welcomed by the scene. To solve the application of this divider instrument encountered each
