Thermistors

Thermometer - Uses
... Indoors, thermistors are used in climate control systems such as air conditioners, freezers, heaters, refrigerators, and water heaters ... thermometers, recording thermometers, thermistors, and Six's thermometers are used outside in areas which are well-exposed to the elements at various levels of the Earth's atmosphere and within the ... Bi-metallic stemmed thermometers, thermocouples, infrared thermometers, and thermistors are handy during cooking in order to know if meat has been properly cooked ...

Inrush Current Limiter
... Negative temperature coefficient (NTC) thermistors and fixed resistors are often used to limit inrush current ... NTC thermistors can be used as inrush-current limiting devices in power supply circuits when placed in series with the circuit being protected ... As current continues to flow, NTC thermistors heat up, allowing higher current flow during normal operation ...

Thermistor
... A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors ... Thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements ... Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals ...

Thermistor - Applications
... PTC thermistors can be used as current-limiting devices for circuit protection, as replacements for fuses ... PTC thermistors were used as timers in the degaussing coil circuit of most CRT displays ... initially switched on, current flows through the thermistor and degaussing coil ...
