Laboratory 8: Using Thermocouples for Temperature and Heat Transfer Measurements
-
This lab will have two parts. In part (1) you will build an amplifier circuit for the TC output, and then calibrate both unamplified and amplified type "J" thermocouple outputs against reference temperature measurements. These calibrations allow absolute temperatures to be derived from the TC outputs. In part (2) will use the calibrated thermocouples to indirectly measure the convective heat transfer to a penny immersed in a beaker of hot water. This lab will allow students to understand the difference between temperature and heat.
Lab may span 2 weeks.
- Laboratory Performed During Week
- Report Due @ Beginning of Lab Sessions
- Each MAE 3340 lab section will design, build, integrate and test prototype oximeter d
esigns based on 1) photo-resistive, and 2) photo-generation technology.
- Each team will use the designs to evaluate team member resting pulse-rate and pulse-rate following vigorous activity (one round-trip up 4 flights of stairs in the ENGR building).
- Project team will use appropriate statistical analysis methods to make projections for the USU Engineering student body with regard to the resting heart rate and heart rate following vigorous activity (maximum heart rate).
- These projections will be compared to the USA population at large.
- Each laboratory section will work together as an integrated product team (IPT) with the entire team contributing to the development and testing of the final product.
