  • Seebeck and Peltier Effects V
    Seebeck and Peltier Effects Introduction Thermal energy is usually a byproduct of other forms of energy such as chemical energy, mechanical energy, and electrical energy. The process in which electrical energy is transformed into thermal energy is called Joule heating. This is what causes wires to heat up when current runs through them, and is the basis for electric stoves, toasters, etc. Electron diffusion e e T2 e e e e e e T2<T1 e e e e e e e e cold hot I - + V Figure 1: Electrons diffuse from the hot to cold side of the metal (Thompson EMF) or semiconductor leaving holes on the cold side. I. Seebeck Effect (1821) When two ends of a conductor are held at different temperatures electrons at the hot junction at higher thermal velocities diffuse to the cold junction. Seebeck discovered that making one end of a metal bar hotter or colder than the other produced an EMF between the two ends. He experimented with junctions (simple mechanical connections) made between different conducting materials. He found that if he created a temperature difference between two electrically connected junctions (e.g., heating one of the junctions and cooling the other) the wire connecting the two junctions would cause a compass needle to deflect. He thought that he had discovered a way to transform thermal energy into a magnetic field. Later it was shown that a the electron diffusion current produced the magnetic field in the circuit a changing emf V ( Lenz’s Law). The magnitude of the emf V produced between the two junctions depends on the material and on the temperature ΔT12 through the linear relationship defining the Seebeck coefficient S for the material.

  • In-Situ Measurement and Numerical Simulation of Linear
    IN-SITU MEASUREMENT AND NUMERICAL SIMULATION OF LINEAR FRICTION WELDING OF Ti-6Al-4V Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Kaiwen Zhang Graduate Program in Welding Engineering The Ohio State University 2020 Dissertation Committee Dr. Wei Zhang, advisor Dr. David H. Phillips Dr. Avraham Benatar Dr. Vadim Utkin Copyrighted by Kaiwen Zhang 2020 1 Abstract Traditional fusion welding of advanced structural alloys typically involves several concerns associated with melting and solidification. For example, defects from molten metal solidification may act as crack initiation sites. Segregation of alloying elements during solidification may change weld metal’s local chemistry, making it prone to corrosion. Moreover, the high heat input required to generate the molten weld pool can introduce distortion on cooling. Linear friction welding (LFW) is a solid-state joining process which can produce high-integrity welds between either similar or dissimilar materials, while eliminating solidification defects and reducing distortion. Currently the linear friction welding process is most widely used in the aerospace industry for the fabrication of integrated compressor blades to disks (BLISKs) made of titanium alloys. In addition, there is an interest in applying LFW to manufacture low-cost titanium alloy hardware in other applications. In particular, LFW has been shown capable of producing net-shape titanium pre-forms, which could lead to significant cost reduction in machining and raw material usage. Applications of LFW beyond manufacturing of BLISKs are still limited as developing and quantifying robust processing parameters for high-quality joints can be costly and time consuming.

  • Room Temperature Seebeck Coefficient Measurement of Metals and Semiconductors
    Room Temperature Seebeck Coefficient Measurement of Metals and Semiconductors by Novela Auparay As part of requirement for the degree of Bachelor Science in Physics Oregon State University June 11, 2013 Abstract When two dissimilar metals are connected with different temperature in each end of the joints, an electrical potential is induced by the flow of excited electrons from the hot joint to the cold joint. The ratio of the induced potential to the difference in temperature of between both joints is called Seebeck coefficient. Semiconductors are known to have high Seebeck coefficient values(∼ 200-300 µV/K). Unlike semiconductors, metals have low Seebeck coefficient (∼ 0-3 µV/K). Seebeck coefficient of metals, such as aluminum and niobium, and semiconductor, such as tin sulfide is measured at room temperature. These measurements show that our system is capable to measure Seebeck coefficient in range of (∼ 0-300 µV/K). The error in the system is measured to be ±0:14 µV/K.

CRITERIA FOR TEMPERATURE SENSOR SELECTION OF T/C AND RTD SENSOR TYPES Part 1 of 3: The Basics of Temperature Measurement Using Thermocouples Background Temperature reigns as the most often measured process parameter in industry. While temperature measurement utilizes sensors of many forms, the actual measurement of temperature is accomplished via only five basic sensor types: Thermocouple (T/C), Resistance Temperature Detector (RTD), Thermistor, Infrared Detector, and via semiconductor or integrated circuit (IC) temperature sensors. Of these five common types, the thermistor is perhaps the most commonly applied for general purpose applications. Semiconductor sensors dominate most printed circuit board or board level sensing applications. Infrared is used for non-contact line-of-sight measurement. But for industrial applications that typically employ remote sensing, thermocouples and RTD’s reign as the most popular sensor types. Most industrial applications require that a temperature be measured remotely, and that this signal be transmitted some distance. An industrial transmitter is commonly used to amplify, isolate, and convert the low-level sensor signal to a high level signal suitable for monitoring or retransmission. With respect to these transmitters, your choice of sensor type is generally limited to T/C, or RTD.

  • How to Maximize Temperature Measurement Accuracy
    technicalNOTE How to Maximize Temperature Measurement Accuracy INTRODUCTION Thermocouples are the most versatile and widely used devices for temperature measurements. They are inexpensive, reliable, rugged, and can be used over a wide temperature range. These sensors require cold junction compensation and complex linearization algorithms to achieve good accuracy. The output voltage of thermocouples is very small (tenths of mV) and hence require high gain amplifiers before being fed to the ADC. Any errors and non-linearity in these areas of signal conditioning and amplification will lead to inaccurate measurements. Most test engineers are careful about the measurement errors caused by thermocouples, but not always about the measurement system. Measurement systems are calibrated regularly (typically once per year) at ambient room temperatures and are expected to perform throughout the year with the same accuracies. What if the measurement system is placed where the temperature is not at ambient room temperature? Is the measured data accurate? This application note focuses on this lesser known and important aspect called “Self-Calibration”. Measurement instruments will be highly accurate only when they are compensated for conditions like gain drifting, aging and temperature variations. PRIMARY SOURCES OF ERRORS WITH THERMOCOUPLE MEASUREMENTS Let us look at the Primary Error Sources. They can be broadly categorized as: 1) Errors due to the measurement system 2) Errors due to the thermocouple CJC Errors: CJC error is one of the single largest contributors to overall accuracy. CJC is responsible for compensating the voltage difference as cold junction is not maintained at an ideal zero temperature.
