Application

PTC thermistors are used for monitoring a specific temperature limit, which is determined by a previous selection of the PTC thermistor type. It is also known as nominal response temperature (NAT) of the thermistor. The NAT covers a range between of +90°C to +190°C acc. to DIN EN 44 080 - 82.

Structure / Functional principle

The thermistors are installed electrically isolated in different housing types. PTC thermistors are used for monitoring a temperature limit, beyond which the nominal resistance of below  <100 Ohm quickly rises. This significant increase in resistance is detected usually by means of PTC evaluation device which allow additional functions or actions by potential-free switching contacts.
