很多行业对温度测量控制的要求较高 ,为了防止测温仪表失灵造成质量事故 ,一般采用两套测温仪表 (如电子电位差计和动圈式温度指示调节仪 )进行分别指示 ,共同调节控制同一处温度 ,给生产带来方便和安全。不少企业在测温现场发现 ,两块测温仪表温度指示不一致 ,有的相差还很大
Many industries have higher requirements on temperature measurement and control. In order to prevent quality accidents caused by failure of the temperature measuring instruments, two sets of temperature measuring instruments (such as an electronic potentiometer and a moving coil temperature indicator) are respectively used for indication and adjustment together The same temperature, to bring convenience and safety of production. Many companies found in the temperature measurement site, two temperature measurement instrument indicates inconsistent, and some differences are still large
