【摘要】 研制了一种适合工业过程控制的分光光度在线分析仪。它能测量在360～1000nm波长范围具有吸收峰的液体样品。用光缆连接的测样探头能直接插入工业过程溶液，进行实时在线分析。分析仪内置微机，测量可按使用者自编程序自动运行，并能存贮数据、计算和报出测量结果。分析仪能通过RS－232接口与外部计算机连接。该在线分析仪已成功地用于稀土萃取分离过程的在线分析和自动控制。更多还原

【Abstract】 An optical fiber spetrophotomtric on-line analyzer was developed for industrial process control . It can determine liquid samples with ahation peaks in the range of 360 ~ 1000nm. The sampling probe connected with optical fiber cable can be inserted into the solution of industrial process directly for real-time analysis. The built-in microprocessor allows the messurement to be performed automatically under the control of user’s program and the analyzer can be connected with the external computers through RS-232 interface. The instrument has been used for on-line analysis and automatic control of rare earth extraction proced sucessfully更多还原
