PTC thermistor probe

The PTC (positive temperature coeficient) thermistor is a thermally sensitive semiconductor resistor, the resistance increases with increasing temperature.

PTC thermistor sensors

The measurement PTC thermistor sensor:

Resistors with silicon have a fairly uniform positive temperature coefficient (around + 0,77% / C) over most of their operating range, often used for temperature measurement and temperature compensation.

The thermal protection PTC thermistor sensor :

Made of doped polycrystalline ceramic based on barium titanite (major BaTio3 material). The resistance increases strongly at the Curie temperature. Used for :

- overload protection

- protection against overcurrents

- protection against overheating

- self-regulating heating

- starting the engine

- progressive lighting start-up, etc.

PTC thermistor

Silicone PTC linear thermistors. These temperature sensors are encapsulated in glass with inside an element equivalent to the following elements KTY84 KTY83 KTY81, R25 600, 1000, 2000 ohm. Resistance increases with increasing temperature in linearity, silicon temperature sensors exhibit fail-safe operation when a system overheats. Moreover, silicon is inherently stable with very long operational life, widely applied in temperature sensing and control in drives and motors.

These PTC thermistorsSingle and triple PTC thermistor have a resistance that increases exponentially as the Curie point approaches. They are suitable for monitoring temperature limits.

For example:

- To turn on a fan when a particular temperature is reached.

- For the detection of overheating of windings in electric motors, coils, transformers, equipment, machines, etc.
