PNliitoslämpötilaanturit
PNliitoslämpötilaanturit, also known as PN junction temperature sensors, are semiconductor devices that utilize the inherent temperature-dependent characteristics of a PN junction to measure temperature. A PN junction is formed by joining a p-type semiconductor material with an n-type semiconductor material. When a current flows through this junction, a voltage is developed across it. This forward voltage drop is directly influenced by the temperature of the junction.
As the temperature increases, the forward voltage drop across the PN junction decreases. Conversely, as the
The output signal from a PNliitoslämpötilaanturi is usually a voltage that changes linearly with temperature over
