| Abstract | To ensure the hydro-energetic building reliability, specific quantities need to be monitored. The temperature, pressure, deformation, mechanical stress, etc. are often measured using resistive gauges, spread in the whole structure of the construction. The resistive transducers are based on the resistive variation and constructive are realized by one or two resistances in serial connection. To measure the resistive transducer can be used the consecrate method, Wheatstone bridge. To define the Wheatstone bridge is used one or two resistances from transducer, and other two is the reference resistor, located on the measurement system, which complete the circuit. Because the measurement is make different atmospheric condition (summer, winter), reference resistances are changing the value. For this cause using the reference resistor introduce the measurement errors. An embedded microcontroller system with a programmable analog to digital converter, which used only the transducer resistances, eliminates the error dependents by temperature and compensate the connection wires. The purpose of this article is a measurement method using a 16 bit sigma delta converter, which give the 0.001% precision for obtain values |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
