由西安仪表厂开发生产的WJ—30T味精发酵罐微机控制系统,于86年9月在四川省万县市发酵公司投运成功,该系统能对罐温、罐压、通风量、PH值、CO_2、O_2溶解氧(D·O)及光密度(O·D)等过程参数进行检测及对罐温、罐压、通风量和PH值进行实时控制。同时,可对全部过程参数进行定时或随机打印制表。该系统控制精度和可靠性高,具有完备的模拟备用系统,是一种理想的通用工
The microcomputer control system of WJ-30T MSG fermenter developed and produced by Xi’an Instrument Factory was successfully put into operation in Fermentation Co., Ltd. of Wanxian City, Sichuan Province in September, 86. The system can test the temperature, tank pressure, ventilation capacity, PH value, CO_2, O_2 dissolved oxygen (D · O) and optical density (O · D) were measured and the tank temperature, tank pressure, ventilation rate and PH value were controlled in real time. At the same time, all the process parameters can be scheduled or random print tabulation. The system control accuracy and high reliability, with a complete analog standby system, is an ideal general-purpose workers
