PT100 vs. PTC: The right temperature sensor for your application
PT100- sensors and PTC thermistors are two different types of temperature sensors based on different physical principles.
Comparison of functionality
Both sensor types have their specific applications and advantages, depending on the requirements of the respective application. PT100 sensors are ideal for precise measurements over a wide temperature range, while PTC thermistors are suitable for protection and heating functions.

PTC-resistor temperature sensors (also called PTC-resistors or thermistors) are temperatur dependent semiconductor resistors whose main function is to alter their electrical resistance drastically when their body temperature reaches the nominal trip temperature NAT (TNF).PTC-resistors are used principally to protect windings in electromotors or transformers against excess temperature. They also find application in machines, tooling machines especially machine bearings and controlling the temperature of power semiconductors.PTC-resistor temperature sensors are particularly suited to this purpose due to their precise response range combined with small dimensions and minimal thermal inertia at low cost.
