P a g e | 3 Introduction The purpose of this lab is to gain a understanding of the common temperature sensors, the Wheatstone bridge circuit with a thermistor and a K-Type Thermocouple. The Wheatstone bridge circuit interfaces with the thermistor to measure temperature. The K-Type Thermocouple produces a voltage difference in order to measure temperature via the Seebeck Effect. Materials and Methods Part 1: Building a Thermometer Using a Thermistor and Wheatstone Bridge Circuit First, a thermometer was built using a thermistor and the Wheatstone bridge circuit. The Wheatstone bridge circuit was constructed as shown in figure 1. The potentiometer was used for “R2”, which has 3 connections. The difference between V1 and V2 was measured by connecting a wire from V2 to ACH5+ and V1 to ACH5-. Figure 1: Wheatstone bridge circuit The voltage difference was monitored through LabVIEW. Once the VI (thermistor.vi; shown in fig. 2) was implemented, the bridge was balanced at room temperature by adjusting the potentiometer until the voltage difference was zero. Balancing the bridge means adjusting the resistors until the voltage difference is zero.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
