Thermistors/Temperature Measurement with NTC Thermistors

Figure 2: Thermistor temperature-resistance curve -40°C to 60°C The manufacturer's data sheet includes a list of thermistor resistance values and corresponding temperatures over its range. One solution for dealing with this non-linear response is to include a look-up table containing this temperature-resistance data in your code. After calculating the resistance (to be described later) your ...

How to use NTC Thermistor to measure Temperature? – A blog ...

· Choosing a Thermistor temperature sensor. When you buy a NTC thermistor, there are 3 important information that need to know. 1) Resistance value As stated earlier, the resistance of an NTC thermistor is changing depending on temperature. However, in order to rate a thermistor, the standard temperature that most manufacturers use is the 25 degree Celsius which is equivalent to room temperature ...

Using a Thermistor | Thermistor | Adafruit Learning System

· A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. Technically, all resistors are thermistors - their resistance changes slightly with temperature - but the change is usually very very small and difficult to measure. Thermistors are made so that the resistance changes drastically with temperature so that it can be 100 ohms or more of change per degree ...

Thermistors and NTC Thermistors - Basic Electronics Tutorials

The Thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive. Thermistors can be used to produce an analogue output voltage with variations in ambient temperature and as such can be referred to as a transducer. This is because it creates a change in its electrical properties due to an external and physical change in heat ...

Thermistor-Thermometer | Hanna Instruments Deutschland GmbH

Ein Thermistor ist ein Halbleiter, der seinen Widerstand (R) in Abhängigkeit von der Temperatur (T) ändert: R = R 0 • (1 + a(T-T 0)). wobei R 0 der Widerstand ist zum Beginn der Messung, bei einer Anfangstemperatur T 0 und a der Temperatur/Widerstands-Koeffizient ist. a bestimmt, je nach Vorzeichen, ob die Änderung des Widerstands positiv oder negativ ist.

Heißleiter – Wikipedia

Ein Heißleiter, NTC-Widerstand oder NTC-Thermistor (englisch Negative Temperature Coefficient Thermistor) ist ein temperaturabhängiger Widerstand, welcher zu der Gruppe der Thermistoren zählt. Er weist als wesentliche Eigenschaft einen negativen Temperaturkoeffizienten auf und leitet bei hohen Temperaturen den elektrischen Strom besser als bei tiefen Temperaturen.

High temperatures cause the semiconducting material to release more charge carriers. In NTC thermistors made from ferric oxide, electrons are the charge carriers. In nickel oxide NTC thermistors, the charge carriers are electron holes. Let’s build a basic thermistor circuit to see how it works, so you can apply it to other projects later.
