Measurements and Instrumentation

This course covers the fundamentals concepts of measurement and instrumentation. Through theory, labs assignments and projects design using NI ELVIS III, students will learn about various types of sensors and when to use the them. Students will be given design requirements and they will determine which sensor is best suited for the requirement. Students will learn about the different stages for taking a measurement, from signal conditioning and how to prepare the signal for processing, analog-to-digital converter and sampling characteristic, to software processing and analysis techniques to display the data. By completing this course, students will learn how to take measurements of real-world phenomenal which are crucial in all engineering disciplines.

LEARNING OBJECTIVES

 
  1. Given a measurement need, students will interpret which signal characteristics need to be measured and select an appropriate sensor based on sensor specifications.
  2. Students will be able to obtain a high-quality, digitized signal from a raw sensor measurement by designing and building an appropriate signal conditioning circuit and implementing data acquisition techniques.
  3. Given an acquired data set, students will be able to program a virtual instrument to preform and present analyses, and draw conclusions based on the analysis findings.
  4. Given a simple measurement need for a common physical phenomena like temperature, strain, or pressure students will be able to design and implement an appropriate measurement system, including sensors, signal conditioning, data acquisition, data analysis, and data presentation.

INCLUDED COURSE LABS

In this lab, students will learn about various sensors, when to use them and their characteristics. Students will learn about the various signals that are used to measure the sensors. There are three activities in this lab, first students will investigate an IR sensor by taking measurements. Second, students will be given temperature and strain measurement scenario with specifications and several sensor choices. Based on the specification, students decide which sensor is best suited for the application.
In this lab, students will learn the importance of signal conditioning in a data acquisition system. First, they will learn how analog signals are prepared for digitizing using various methods such as amplification, attenuation, filtering. Next, students will learn about the different circuits that are used for signal conditional. The students will design a signal conditioning circuit in a simulator and then verify their design using a sensor. Throughout the process, they will be answer short question to confirm their understanding.
In this lab students will learn how analog signals from sensors are converted into a digital signal using analog-to-digital conversion (ADC). Students will also learn about elements of ADC such as sampling and Nyquist frequency. Through the process, students will complete hands-on activities and answer questions to confirm their understanding.
In this lab, students will complete activities in data acquisition, which involves storing, analyzing and presenting data on a PC. They will learn how extract information from the input signal using methods such as Fourier Transform and statistic so that data can be presented and easy to interpret.
In this project, students will use methodologies outlined in the previous labs to design and implement their own temperature measurement system for a given measurement need. Students will determine the right sensor, signal conditioning circuit, ADC sampling, software approach, and analysis methods for the given measurement scenario. Once they complete design, students will build and iterate on the measurement system, and verify if the requirements were met.
