我厂二车间两座步进式加热炉在1987年10月实现微机控制,但因采用的DKJ—Ⅲ型电动执行器不能适应计算机频繁调整而使微机应用不能获得预期的综合效益。正在此时我们得知天津市自动化仪表七厂引进法国伯纳德电动执行器问世,就抱着试试看的心理先购买一台(AS-25),经与微机配套使用,使微机控制达到预期效果。在厂领导的支持下,我们又买40套 I plant two workshops two step furnace in October 1987 to achieve computer control, but because of the use of the DKJ-Ⅲ-type electric actuator can not adapt to frequent computer adjustments so that the microcomputer can not achieve the expected comprehensive benefits. At this moment we learned that Tianjin Automation Instrumentation Plant Seven introduced the introduction of the French Bernard Electric Actuators, try to hold the psychological first to buy one (AS-25), supporting the use of computer, microcomputer control to achieve the expected effect. With the support of the factory leaders, we buy another 40 sets
