Abstract

Mediante la calibración es posible asegurar que los instrumentos están midiendo de manera correcta, de esta forma se garantiza la fiabilidad y trazabilidad de las mediciones. El objetivo del trabajo fue calibrar el Proyector de Perfiles Digital CPJ 3025A. Se realizó la  calibración de los ejes X, Y y la escala angular del proyector para la iluminación diascópica (proyección por luz transmitida). Para la calibración se emplearon bloques patrón y patrones angulares, el procedimiento de calibración empleado fue el publicado por el Centro Español de Metrología. Como resultado se obtuvieron las incertidumbres para cada uno de los puntos analizados, así como las curvas de calibración de los ejes y se concluyó que los errores obtenidos no superan los permisibles por lo que no se requiere realizar ningún tipo de ajuste del proyector ni de corrección de datos.

Palabras claves: calibración; proyector de perfiles; bloques patrón.

Abstract

By means of the calibration it is possible to be sure that the instruments are measuring correctly in order to guarantee the reliability and traceability of the measurements. The objective of the work was to calibrate the Digital Profile Projector CPJ 3025A. The calibration of the X, Y axes and the angular scale of the projector is performed for diascopic lighting (transmitted light projection). For the calibration were used gauge blocks and angular gauge, the procedure used was that published by the Spanish Metrology Center. As a result were obtained uncertainties for each of the points, as well as the calibration curves of the axes and the author conclude that the calculated errors do not exceed the permissible, so the projector offers reliable measurements and the instrument does not require adjustments or corrections to the measurement results.

Key words: calibration; profile projector; gauge blocks.
