摘　要:對西門子PLC（可編程控制器）在薄膜測厚儀上的應用進行了研究，并比較了傳統的以工控機為核心的電控系統與以PLC為電控核心的系統的優缺點。詳細介紹了測厚儀電控系統的組成和原理，同時對測厚數據的處理方法進行了說明。實踐表明，該系統控制結構簡單，有較高的運行效率和可靠性。整套裝置已成功運行在聚丙烯雙向拉伸薄膜生產線上。[著者文摘]

Research on the Technique of X-ray Thickness GaugeAbstract:The application of SIEMENS PLC in thickness gauge of thin films is studied, and the merits and demerits of electric control systems based on industrial computer and PLC are compared. The composition and principle of the electric control system of the thickness gauge are introduced in detail, and the method of data processing is explained. The practice shows that the control system is simple, high efficient and reliable. The whole plant has been successfully used on production line of thin film of polypropylene.[著者文摘]
