我厂应用的热电偶种类与数量较多,校验热电偶的任务很重。为了多快好省地建设社会主义,我们遵照毛主席自力更生的教导,自制了热电偶校验台,可方便地对各种热电偶进行校验,精度不小于零点五级。本校验台由毫伏毫安转换器、DDZ-Ⅱ型调节器、可控硅调压器、记录表及一些延时报警机构等组成。由标准热偶测量来的 I plant more types and the number of thermocouples, thermocouple calibration task is heavy. In order to build socialism more quickly and economically, in accordance with Chairman Mao’s self-reliance education, we have made a thermocouple checkout table that can be conveniently calibrated to various thermocouples with accuracy not less than zero and five. The school bench by the millivolt millianhuan converter, DDZ-Ⅱ-type regulator, SCR regulator, record and some delay alarm agencies and other components. Measured by standard thermocouple
