我厂DDZ—Ⅲ型热电偶温度变送器(以下简称仪表)的设计改进工作是从该仪表的联合设计方案着手的。通过试验发现,在目前国产元件质量差的情况下,如果不针对具体问题采取改进措施,在仪表的大量生产中必然会造成重复性差、性能不稳定和某些指标达不到要求等问题,这将直接影响到仪表的产量和系统的配套。为此在试制中对线路和结构作了一定的修改。实践证明按修改的方案制造出来的仪表,性能稳定、元件上机率高,节约工时,生
Our factory DDZ-Ⅲ thermocouple temperature transmitter (hereinafter referred to as the instrument) design and improvement work is from the instrument joint design to proceed. Through the test, we found that in the current situation of poor quality of domestic components, if we do not take measures to improve the specific problems, it will inevitably cause problems such as poor repeatability, instability of performance and failure of some indexes in mass production of instruments. Will directly affect the output of the instrument and system support. To this end in the trial of the circuit and structure made some changes. Practice has proved that the instrument manufactured by the revised program, stable performance, high probability of components, saving hours, students
