Thermal transducers are devices that convert temperature changes into electrical signals. They are commonly used in various applications, such as thermometers, temperature sensors, and thermostats. These devices can detect heat variations and provide accurate readings, making them essential in industries like HVAC, automotive, and electronics. There are different types of thermal transducers, including thermocouples, thermistors, and infrared sensors. Each type operates on specific principles, such as changes in resistance or voltage in response to temperature changes. By translating thermal energy into measurable electrical signals, thermal transducers play a crucial role in monitoring and controlling temperature in various systems.
