lämpötilatunnistinprincipiä
Lämpötilatunnistinprincipiä refers to the fundamental working principles behind temperature sensors. These devices detect and measure temperature by exploiting various physical phenomena that change predictably with temperature variations. The choice of principle depends on the application's requirements for accuracy, range, response time, and cost.
One common principle involves electrical resistance. Resistive temperature detectors (RTDs) and thermistors change their electrical resistance
Another principle utilizes the thermoelectric effect. Thermocouples generate a voltage proportional to the temperature difference between
Semiconductor-based sensors also operate on temperature-dependent electrical characteristics, such as the voltage drop across a PN
