lämpötilasensoreiden

Lämpötilasensoreiden are devices used to measure temperature. They work by detecting changes in physical properties that are related to temperature. These changes can be electrical, optical, or mechanical. The most common types of temperature sensors are thermistors, thermocouples, resistance temperature detectors (RTDs), and infrared sensors. Thermistors are semiconductor devices whose resistance changes significantly with temperature. Thermocouples are made of two dissimilar metals joined at one end, and the voltage produced at the junction is proportional to the temperature. RTDs are made of a metal wire, typically platinum, whose resistance increases with temperature. Infrared sensors measure the thermal radiation emitted by an object, allowing for non-contact temperature measurements. Temperature sensors are used in a wide variety of applications, including industrial processes, medical devices, automotive systems, and consumer electronics. The choice of sensor depends on factors such as the required temperature range, accuracy, response time, and environmental conditions. Calibration is essential for ensuring the accuracy of temperature sensor readings.
