| Abstract (English): |
Se describe el proceso de montaje y evaluación de un equipo de la firma india Ambala Electronics Instruments conforme con la documentación que lo acompañaba. La misma era muy deficiente en cuanto a los fundamentos teóricos y en los procedimientos prácticos. Al montaje original se le adicionaron dos dispositivos que permitían conmutar el sentido de la corriente por la placa semiconductora y el del campo magnético en la dirección perpendicular a ella. Esto estaba sugerido en el procedimiento para realizar las mediciones del voltaje Hall, pero sin las facilidades para realizarlas y tampoco cómo proceder con las cuatro mediciones obtenidas. Inicialmente se realizaron las mediciones y se procesaron conforme a dicha documentación. Con posterioridad se realizó el procesamiento de las mediciones para minimizar los efectos termomagnéticos presentes que no se tomaban en cuenta en la documentación de los fabricantes. Se compararon los resultados obtenidos y se muestran las diferencias. Para el nuevo montaje se muestra cómo los resultados obtenidos tienen buena correspondencia con los datos reportados en la literatura. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): |
In the paper is described the assembly process and evaluation of an equipment of the Indian firm Ambala Electronics Instruments consistent with the documentation that accompanied it. The documentation was very poor in terms of the theoretical foundations and practical procedures. To the original assembly were added two devices permitting switch the direction of current by the semiconductor plate and the magnetic field in the direction perpendicular thereto. This was suggested in the procedure for measurement of the Hall voltage, but without the facilities to perform, nor how to proceed with the four measurements obtained. Initially, measurements were made and processed as indicated in that documentation. Later, subsequent processing of the measurements was performed to minimize the present thermo-magnetic effects that were not taken into account in the documentation of the manufacturers. The results were compared and differences were shown. For the new assembly was shown how obtained results have a good degree of correspondence with the data reported in the literature.
