Diseño e implementación de herramientas interactivas de instrumentación virtual para el Laboratorio de Sensores y Transductores de la Escuela Politécnica Nacional : Diseño e implementación de la herramienta interactiva de instrumentación virtual para las prácticas del laboratorio de Sensores y Transductores relacionadas con la variable presión.

Abstract

The present work exposes the design and development of three laboratory practices referring to the physical variable of pressure within the 3D virtual instrumentation environment "Sensor Zone", whose purpose is to provide interactive interfaces that facilitate the teaching and learning of handling, characteristics, connections. electricity and applications of pressure transmitters, to the students who study the subject of Sensors and Transducers at the National Polytechnic School. Said practices named as: Practice 7 - "Relative Pressure Transmitter with Current Output", Practice 8 - "Relative Pressure Transmitter with Voltage Output" and Practice 9 - "Difference Pressure Transmitter with Current Output", are implemented through the Unity 3D 2019.4.29f development engine, whose elements, electronic components, measuring instruments, as well as the electrical connection are modeled in 3D using Autodesk Inventor and Blender CAD software. The pressure practices are used by 20 students who are taking the subject of Sensors and Transducers to verify their correct operation and finally, through a survey, the developed interfaces are evaluated through the following evaluation criteria: presentation design, interaction usability, motivation and learning objectives, which allow validating the virtual tools used for teaching and learning.
