How does a Thermistor Work? This page is dedicated to providing you with the information and resources you need to broaden your knowledge base, thus providing answers to your questions as well. As mentioned earlier the resistance of the thermistors decreases with the increase its temperature. 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. By combining the thermistor with appropriate additional circuits and controls the thermostat uses the change in resistance to control the switching of the thermostat's control of cooling or heating on or off in response to room temperature. There are two types of Thermistors, NTC Thermistors, ( Negative Temperature Coefficient) and PTC … The Thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive. A thermistor is a thermally sensitive ceramic semiconductor which exhibits a change in resistance as the temperature changes. The term thermistor is a contraction of the words "thermal" and "resistor". A thermistor is a temperature sensitive resistor, they are often used as a temperature sensor. A thermistor’s resistance will vary non-linearly throughout its useful range, and how each device behaves will depend on its construction. All resistors have some dependency on temperature, which is described by their temperature coefficient. Principle of Working of Thermistors. Electricity. The plot is unusual because it shows that a bigger current will flow Thermistor Shapes. The resistance of thermistor is given by: R = Ro ek. Learn more about thermistor resistance in a temperature versus resistance chart, modeled via the Steinhart-Hart equation, or the simplified B parameter equation. A thermistor is a component whose resistance changes when its temperature changes. K = β(1/T – 1/To) Where R is the resistance of the thermistor at any temperature T … They are widely used in many different liquid and ambient air environments as a means of measuring temperature as a thermistor thermometer.Some of the thermistors ‘ most common uses include: They have three main uses: measurement, control and protection. Thermistor sensor applications often require a particular type of thermistor temperature sensor depending on whether you are seeking to measure, control, or compensate temperature. Thermistors have a wide range of applications. A thermistor is a special type of resistor whose resistance decreases as its temperature increases.. A plot of resistance against temperature for a thermistor is shown above. A thermistor is an electronic component whose resistance changes with temperature. Thermistor.. What is a Thermistor?. Uses of Thermistors.
