| Abstract | In the aviation in-situ eddy current non-destructive testing (ECNDT), there are increasing requirements for speediness, intelligence and integration. The signal conditioning bridge ciruit is one of the most important parts for realizing the requirements. This work proposes an approach to develop a novel digitally controlled bridge (DCB), which is based on relay arrays. It is used for impedance signal processing of ECNDT sensor in aviation in-situ testing. The design ideas, theory analysis, bridge structure, method of realization and performances are presented. A practical in-situ eddy current testing experiment on the aero-engine labyrinth disc was carried out and the experimental results testified the availability and advantages of this work. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
