Thermistor


A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Bu sayfanın çevirisini yap A thermistor is an element with an electrical resistance that changes in response to temperature. This name is derived from the more descriptive term “thermally sensitive resistor”, the original name for these devices.

This is because it creates a change in its . All resistors have some dependency on temperature, which is described by their temperature coefficient.

NTC stands for “Negative Temperature Coefficient”. NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting . How much its resistance will change is dependent upon its unique composition.

And unlike their active . The term is a combination of thermal and resistor. It is made of metallic oxides, pressed into a bea disk, or cylindrical shape and then encapsulated with an impermeable material such as epoxy or . K thermistor with a negative temperature coefficient. Good choice for temp- sensing applications when you need a reliable NTC thermistor.

TE Connectivity manufactures NTC thermistor sensors and probes for a variety of applications in many configurations. Also, thermistors typically have much higher nominal resistance values than RTDs . Heat is generated by the applied voltage and current, and the resistance changes with the change of temperature. These thermistors are pretty hardy, you can strip the PVC insulation and stick the wires into a breadboard or solder to them directly. Of course you can cut or extend the wires.

The resistance of a PTC thermistor increases as the temperature increases. In contrast, the resistance of an NTC thermistor decreases as temperature increases, and this type seems to . The electrical resistance of both devices is determined by their temperature. The name thermistor is a shortening of the words thermally sensitive resistor. This describes the action of the thermistor particularly well.

Today, thermistors are used in a wide variety of devices from temperature sensors through to providing temperature compensation in electronic circuits. As such thermistors are widely . There are two types of thermistors , Positive Temperature Coefficient ( PTC) and Negative Temperature Coefficient (NTC). When the temperature increases, PTC thermistor resistance will increase and NTC thermistor resistance will .
