(1)温度控制器美国Fenwal Inc.(麻省,Ashland)公司开发出144系列微处理机温度控制器。该系列可满足改变工艺过程的PID优化自动调节。开/闭,比例(P),PID,PI(比侧—积分)和PD(比例和微分)控制方式可在键盘上随意选择。可用于热处理及塑性加工。 (2)烟道气体分析器使用Panametrics Inc.(麻省,Waltham)公司的300系列微机控制的烟道气分析器可对热处理炉的燃烧过程进行连续的精确监控。利用氧探头和触媒式可燃成分传感器可测出烟道气中的含氧百分比及微量可燃成分。也可测出空气系数,燃烧指数和可燃成分当量等参数。
(1) Temperature Controller The United States Fenwal Inc. (Ashland) has developed the 144 series microprocessor temperature controller. The series to meet the changing process of PID optimization automatically adjust. On / Off, Proportional (P), PID, PI and PD (Proportional and Derivative) control modes are freely selectable on the keyboard. Can be used for heat treatment and plastic processing. (2) Flue gas analyzer Continuous, accurate monitoring of the combustion process in a heat treatment furnace was carried out using Panametrics Inc.’s 300 series of computer-controlled flue gas analyzers. The use of oxygen probe and catalytic combustible composition sensor can be measured in the flue gas oxygen content and trace flammable components. Can also measure the air coefficient, combustion index and combustible composition and other parameters.
