Thermistor - Wikipedia

A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word is a combination of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type …

What is a Thermistor? How do thermistors work? - EI Sensor ...

A thermistor is a temperature sensor whose electrical resistance changes in response to a change in body temperature. Though the initial concept of an NTC thermistor was first reported in 1833 by Michael Faraday, when he discovered the effect of temperature on silver sulfide, it wasn’t until the 1930’s when the first commercial thermistors were produced. From that time on, countless improvements have been made in thermistor …

Termistor - Omega Engineering

Um termistor é um elemento sensor de temperatura composto por material semicondutor sinterizado, capaz de exibir uma grande alteração de resistência proporcional a pequenas alterações de temperatura. Os termistores geralmente apresentam coeficiente de temperatura negativo, o que significa que a resistência do termistor diminui à medida que a temperatura aumenta.

What is a Thermistor

Cost efficient: Not only are thermistors less expensive than other types of temperature sensors; if the purchased thermistor has the correct RT curve, no other calibration is necessary during installation or over its operational life. Point match: The ability to obtain a specific resistance at a particular temperature. Curve match: Interchangeable thermistors with the accuracy of +˚C to ...

Termístor – Wikipédia, a enciclopédia livre

Termístor (ou termistor) é um semicondutor sensível à temperatura.. Existem basicamente dois tipos de termístores: NTC (do inglês Negative Temperature Coefficient) - termístores cujo coeficiente de variação de resistência com a temperatura é negativo: a resistência diminui com o aumento da temperatura.; PTC (do inglês Positive Temperature Coefficient) - termístores cujo ...

How to calibrate a thermistor? - Frequently-Asked ...

· How do you calibrate a thermistor of unknown value, spec, or manufacturer? I have a few thermistors (plus I have seen others for sale, without any specs, at various surplus dealers) that I don’t know anything about that I would like to calibrate. I first thought that I could simply take one, put it in boiling water, note its voltage reading ...
