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.

Thermistor - Wikipedia

A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard word is a combination of thermal and are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements (positive ...

What is a Thermistor and How Does it Work?

A temperature controller monitors the temperature of the thermistor which then instructs a heater or cooler when to turn on or off, in order to maintain the temperature of the sensor (thermistor), as well as the target device. They are used widely in applications such as air conditioning and display fridges/freezers – upon many more.

Temperature Sensors: Types, How It Works, & Applications

How does temperature sensor work? The basic principle of working of the temperature sensors is the voltage across the diode terminals. If the voltage increases, the temperature also rises, followed by a voltage drop between the transistor terminals of base and emitter in a diode. ...

THERMISTOR BASICS – Wavelength Electronics

Temperature Range: The approximate overall range of temperatures in which a sensor type can be used. Within a given temperature range, some sensors work better than others. Relative Cost: Relative cost as these sensors are compared to one another. For example, thermistors are inexpensive in relation to RTDs, partly because the material of choice for RTDs is platinum.

What Is An NTC Thermistor | Ametherm

Sensors Online. NTC Thermistors are non-linear resistors, which alter their resistance characteristics with temperature. The resistance of NTC will decrease as the temperature increases. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K.

How to replace a window air conditioner ambient thermistor ...

May 01, 2014· The ambient thermistor is a sensor that detects the room air temperature so the electronic control board can regulate the room temperature. If the thermistor isn't working, the air conditioner won't maintain the temperature you set. Replace a malfunctioning ambient thermistor with the manufacturer-approved window air conditioner part.
