在钢水测温中普遍使用的是电子电位差计。这种模拟显示仪表存在着读数误差大,滑线电阻易磨损等缺陷。为此,我们研制了一种由定型仪表组合的数字化装置。其基本功能是: 1.被测温度用四位数字显示,数字可以保持到下次测温或手动复位为止; 2.能自动补偿热电偶冷端温度; 3.自动寻找温度平衡点并采样,同时发出声光信号告诉测温工及时取出测温枪; 4.有断偶声光报警信号,自动显示测温前热电偶是否接通,测温中是否断偶;
Commonly used in the molten steel temperature measurement is the electronic potentiometer. This simulation shows the existence of the meter reading error, slip wear resistance and other defects. To this end, we have developed a combination of digital form by the instrument. Its basic functions are: 1. Measured temperature with four digits, the number can be maintained until the next temperature measurement or manual reset; 2. Can automatically compensate for thermocouple cold junction temperature; 3. Automatically find the temperature balance point and sampling, At the same time the sound and light signals were issued to tell the thermometer to take out the temperature-measuring gun in time. 4. A sound and light alarm signal was turned off, indicating whether the thermocouple was connected before the temperature measurement.
