Was ist ein Thermistor und wie wird er eingesetzt?

· Ein PTC Thermistor( Kaltleiter) ist ein wärmeempfindlicher Sensor, dessen Widerstand signifikant mit der Temperatur ansteigt. Kaltleiter werden unter anderem zum Überlastschutz und zur Strombegrenzung im Dauerbetrieb eingesetzt. PTC Thermistoren finden oft Anwendung im Motorschutz als Übertemperaturschutz und führen bei starker Erwärmung zu einer Leistungsreduktion bzw. …

Thermistor Sensors | Industrial Temperature Sensors

How Thermistor Sensors Work. A thermistor, short for “thermally sensitive resistor”, possesses a variable resistance that changes proportionally with temperature changes. Two types of thermistors exist: NTC thermistors (negative temperature coefficient) exhibit decreasing resistance as temperature increases, while PTC thermistors (positive temperature coefficient) increase in resistance with rising …

Thermistor | Analog Devices

Thermistors are a type of semiconductor, meaning they have greater resistance than conducting materials, but lower resistance than insulating materials. The relationship between a thermistor’s temperature and its resistance is highly dependent upon the materials from which it’s made and is referred to as the temperature coefficient. It is composed of materials with known resistance and ...

Thermistor Applications and Characteristics | PTC and NTC ...

· Thermistors are mainly used as temperature sensors, inrush current limiters, selfresetting overcurrent protectors and selfregulating heating elements. A thermistor is made from a semiconductor material. It is shaped into a disc, a rod or a bead. Bead thermistors may be only a few millimetres in diameter. Some bead thermistors have the bead enclosed in a glass capsule.

· The most common methods use temperature sensors such as the thermistor, resistance temperature detector (RTD), thermocouple, or a silicon thermometer. However, selecting the right sensor is only part of the solution. That sensor must then be connected to a signal chain that maintains the integrity of that signal, while also accurately compensating for the unique characteristics of the ...

NTC Thermistors vs. Resistance Temperature Detectors (RTDs)

Thermistor response times are also superior to RTDs, detecting changes in temperature much faster. The sensing area of a thermistor can be as small as a pin head, delivering quicker feedback. Accuracy: Although the best RTDs have similar accuracies to thermistors, RTDs add resistance to the system. Using long cables can alter readings outside ...
