聚氯乙烯生产装置聚合釜的控制中,釜内反应温度、压力是二个监控生产操作的重要参数。在压力测量中,工艺要求能自动记录。由于本装置生产物料易燃易爆,属甲级防爆场所,强电或带强电性而未加任何其他技术措施的仪表不能使用。多年来,我厂一直使用上海自动化仪表一厂生产的 YT—410压力记录仪表,取压方式采用隔离罐取
Polyvinyl chloride production plant polymerization reactor control, the reactor temperature, pressure is two important parameters to monitor production operations. In pressure measurement, process requirements can be automatically recorded. Due to the flammable and explosive material produced by the device, it belongs to Class A explosion-proof place, strong electricity or instrument with strong electric without any other technical measures can not be used. Over the years, I plant has been using Shanghai Automation Instrumentation YT-410 production of a pressure recorder, take the pressure tank using isolated
