在石油化工、冶金、电站等企业生产过程中,温度是最重要的参数之一,它的测量与控制在自动化中占有相当重要的地位。因此,设法对温度进行稳定、可靠、准确的测量和控制是保证工艺生产高产、优质、低耗的重要环节,也是我们仪表维护人员必须经常注意的问题。近两年来,我们北京石油化工总厂东方红炼油厂,陆续改用了以矩阵开关网路测量温度,收到了很好的效果。现将基本情况概述如下。
In the petrochemical, metallurgy, power plants and other enterprises in the production process, temperature is one of the most important parameters, its measurement and control in the automation holds a very important position. Therefore, trying to temperature for stable, reliable and accurate measurement and control is to ensure that the process of production of high yield, high quality, low consumption is an important part of our instrument maintenance staff must always pay attention to the problem. The past two years, our Beijing Petrochemical Plant Dongfanghong refinery, one after another switch to the matrix switch network to measure the temperature, received good results. The basic situation is summarized below.
