| Abstract from DBPedia | A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor. Thermistors are divided based on their conduction model. Negative Temperature Coefficient (NTC) thermistors have less resistance at higher temperatures, while Positive Temperature Coefficient (PTC) thermistors have more resistance at higher temperatures. Hence, a PTC thermistor's resistance is directly proportional to temperature. NTC thermistor are widely used as inrush current limiters, temperature sensors, while PTC thermistors are used as self-resetting overcurrent protectors, and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type and is typically between −100 °C and 300 °C (−148 °F and 572 °F).サーミスタ（英: thermistor）とは、温度変化に対して電気抵抗の変化の大きい抵抗体のことである。この現象を利用し、温度を測定するセンサとしても利用される。センサとしてはふつう-50℃から150℃程度までの測定に用いられる。サーミスタという名称は英語の thermal(温度) と resistor(抵抗器) とのかばん語である。 (Source: http://dbpedia.org/resource/Thermistor) |
