Most traditional strong magnetic inspection equipment has disadvantages such as big excitation devices, high weight, low detection precision, and inconvenient operation. This paper presents the design of a giant magneto-resistance (GMR) sensor array collection system. The remanence signal is collected to acquire two-dimensional magnetic flux leakage (MFL) data on the surface of wire ropes. Thro...

Significance: Jun 30, 2002 Identified By: NRC Item Type: FIN Finding INADEQUATE DIGITAL FEEDWATER SYSTEM DESIGN AND INADVERTENT GROUNDING OF PLANT EQUIPMENT RESULTS IN REACTOR SCRAM A digital feedwater control system design weakness, in conjunction with the inadvertent grounding of a pressure transmitter during an instrument maintenance surveillance, resulted in a manual reactor scram due to in...

Today’s wafer fabrication plants must carefully balance the need to increase productivity while simultaneously reducing variable costs. There are a couple of main areas where process control (metrology and inspection) equipment can help minimize variable cost. The first is reducing consumables – minimizing the number of wafers that are processed for non-revenue operations, i.e., test wafers. Se...

Hazard installation identification was the key and difficult point for ship power equipment safety management. According to characteristics of equipments, this article analyzed characteristic hazard installations, given range classification identification. Combining checklist routing inspection, method process hazards proposed equipment, which laid a foundation its risk assessment control.

Maintaining civil aircraft air-worthiness requires the reliability of a complex, socio-technic system. This system's reliability is dependent on the reliability of its components (i.e, equipment, inspectors, the physical environment), and on how reliably these components interact. Error is the measurement counterpart of reliability, and most, if not all, errors can be classified at some stages ...
