东南大学研制成功双回路纸浆浓度控制器。该系统由仪表、微机、调节、显示、检测等部分组成，可与２台浓度变送器、２台电动或气动执行机构组合，构成２路浓度控制系统，也就是说，一台控制器可同时控制面浆和底浆的浓度，可大大节约成本。在微机的控制下，完成纸浆浓度的调节 Southeast University successfully developed dual-loop pulp concentration controller. The system consists of instrumentation, microcomputer, regulation, display, testing and other components, with 2 concentration transmitter, 2 electric or pneumatic actuators combined to form a 2-way concentration control system, that is to say, a controller At the same time control the concentration of pulp and pulp, can greatly reduce costs. Under the control of microcomputer, adjust the concentration of pulp
