Thermistor – Wikipedia

Ein Thermistor (Kofferwort aus englisch THERMallysensitive resISTOR) ist ein elektrischer Widerstand, dessen Wert sich mit der Temperatur reproduzierbar ändert. Thermistoren unterteilen sich in ihren Temperaturverhalten in zwei Gruppen: Heißleiter, welche über einen negativen Temperaturkoeffizienten (NTC) verfügen und im heißen Zustand besser als im kalten Zustand elektrisch leiten

Thermistors and NTC Thermistors Basic Electronics Tutorials

A thermistor is basically a solidstate variable resistor that changes its resistive value with a change in ambient temperature, hence its name. Most thermistors have a negative temperature coefficient (NTC), which means its resistance decreases with increasing temperature (PTC’s types are also available). A standard thermistor could have a resistive value of 10kΩ at 25 o C and a nonlinear ...

Was ist ein Thermistor und wie wird er eingesetzt?

· Was ist ein Thermistor? Das Wort Thermistor setzt sich aus dem englischen Begriff THERMally sensitive resISTOR zusammen. Ein Thermistor ist ein variabler elektrischer wärmeempfindlicher Widerstand mit positiver oder negativer Temperaturcharakteristik, der eine starke Nichtlinearität aufweist und deren Wert sich mit der Temperatur reproduzierbar ändert.

Thermistor | NTC PTC Thermistor | Resistance Temperature ...

A typical thermistorbased temperature monitoring circuit uses an analog to digital converter (ADC) to sense the voltage across a thermistor. A small fixed current that has negligible effect on the impedance due to power dissipation causes this voltage. The voltage potential across the thermistor will be directly proportional to the resistance, which in turn is proportional to the temperature ...

Overview | Thermistors | Temperature Sensors |

In addition, unlike NTC thermistors, these linear thermistor sensors offer the ability to calibrate with only a room temperature offset, optimize resolution and reduce the impact of system noise in software, reducing the need for external components or multipoint calibration to achieve accurate measurements.
