在化工、化肥生产过程中,各工艺参数的监视,目前广泛采用JBJ—Ⅱ型等八回路晶体管报警器。这类报警器虽能满足生产过程需要,但大都线路复杂,可靠性差,在应用中维修难度大,价格也较贵。我们试制了一种简单的多回路可
In the chemical industry, fertilizer production process, the monitoring of process parameters, the current widely used JBJ-Ⅱ-type eight-loop transistor alarm. Although this type of alarm to meet the needs of the production process, but most of the line complexity, poor reliability, difficult to repair in the application, the price is more expensive. We tried out a simple multi-circuit can
