In petroleum extraction, temperature sensors are frequently used to detect temperature variations inside oil wells. This helps petroleum companies understand the conditions and situations within the wells, allowing them to optimize extraction plans and maintenance work. One specific type of temperature sensor commonly used in this application is called a "thermocouple." Thermocouples utilize the thermoelectric effect of two different metals or alloy materials to measure temperature changes. They offer advantages such as high sensitivity, fast response time, and high accuracy, making them widely applied in petroleum extraction.
