为提升传统的核子液位测量系统的技术性能,研制了基于PLC的新型核子料位计。新型核子料位计采用抗干扰能力强且发展成熟的西门子PLC（S7-200）代替基于单片机、ARM或DSP的主机部分,结合电流型电离室探测器和适宜的放大电路组成一套结构相对简单、测量精度高、易于快速形成产品的核子液位测量系统。测试结果表明:该仪器的反应时间快、测量精度≤±5 mm,放射源的防护符合国家标准,属于一种高精度环保型核子料位计。

In order to improve the technical performance of the traditional nuclear liquid level measurement system, a new kind of nuclear material level meter which based on PLC has been developed. The new nuclear material position monitor adopts Siemens PLC(S7-200) of excellent anti-jam performance and development as a substitute for main part of the equipment based on singer-chip, ARM or DSP to constitute nuclear liquid measuring system, with comparatively simple structure, high measure precision, strong anti-jam, and easily rapid-making products combi...
