Inline X-ray Fluorescent Multi-element Analyzer ^L. Dandong Dongfang Measurement & Control Technology Co.,Ltd.

Product Composition The inline X- ray fluorescent multi- element analyzer is composed of field devices and control room devices. The field devices are mainly composed of the analyzer (including detector, analytic cells, samplers, signal processors, PLC unit and integral mechanic frame, etc.), power source cabinets and main samplers, etc. The control room devices are composed of industrial computers, etc. Fig. 2-1 and 2-2 show the composition of a typical 6-channel inline X-ray fluorescent multielement analyzer system as well as wiring of measuring systems.

ensures that the measurement result is representative; ◆ Pulps can be easily re- directed from outlets to process points or from several process points to a sedimentation tank. Fig.2-3 Analytic Cell of Inline X-ray Fluorescent Multi-element Analyzer Fig. 2-2 Connection of 6-channel Inline Multi-element Analyzer System 3. Sampler The sampler is located at overflow ports of the analytic cell. The sampling interval and frequency of A sampler is mounted at overflow ports of each analytic cell. The number of analytic cells is samplers can be set through touch screens. The sampler may be operated in...

□andong Dongfang Measurement & Control Technology Co.,Ltd. The PLC unit controls and monitors movement, lifting, measurement and sampling operation of the detector. The PLC unit is able to generate alarms and protect the analyzer from damage in case of various abnormal conditions. It transmits analyzer operation status to X-ray fluorescence software via RS- 485/RS232 data communication ports. The users can perform the required functions using buttons on the control box or touch screens. It is a basic element of a success of any inline analyzer system to present pulp samples correctly to the multi-element...

Operating Principle Performance Parameters The inline X-ray fluorescent multi-element analyzer takes samples at field process points through 1. Instrument Dimension Table 4-1 Instrument Dimension the main sampler. Representative samples are directed to the analytic cell through pulp piping. The PLC unit controls the movement of the detector carriage. The detector carriage moves among all analytic cells within the minimum time so the detector measures pulps in each analytic cell in a Net weight of 6-channel X-ray fluorescent analyzer real- time and inline mode. The signal processor acquires, amplifies,...

Product Feature Product Application ◆ Real- time analysis: Most of domestically- made X- ray fluorescent analyzers are offline The inline X-ray fluorescent multi-element analyzer can be widely applied to non-ferrous metal, laboratory analyzers. Few instruments which are applied at sites are off- site types and provide metallurgic, ore dressing, cement and chemical industries, etc. analysis results after serial and complex sample pre- processing processes including sampling, Application cases: In March, 2008, an inline X- ray fluorescent multi- element analyzer (Fig. 6- 1) drying, screening, grinding...
