4 Most Common Types of Temperature Sensor | Ametherm

2020-02-13· The number of calibration points you’ll need depends on the type of thermistor you’re using and the temperature range of your application. For narrow temperature ranges, one point of calibration is fine for most thermistors. For applications requiring a wide temperature range, you have two options: 1) Calibrate three times using an NTC ...

Thermistor temperature sensing circuit design solution_

The disadvantage of the thermistor is that its output is linear and accurate only over a narrow temperature range, and becomes non-linear outside of this range. Figure 2 plots the output curves of three thermistors with biasing resistances of 1 MΩ, 35 kΩ, and 10 kΩ, respectively. Each curve is linear over a narrow temperature range, but the three curves are non-linear when the bias ...

of less than °C over a temperature range of -30°C to +125°C, and errors of less than °C between -20°C to +50°C. Thermistor Families - Most thermistors have a negative temperature coeffi cient (NTC), which means resistance decreases with increasing temperature. The R-T character-istics of nine common NTC thermistors are

Temperature Measurement: Thermistors, Thermocouples, and ...

The third most common temperature sensor is the thermistor. A thermistor functions similarly to a RTD in that it exhibits a change in resistance associated with a change in temperature. A difference between the two is that, instead of using pure metal, thermistors use a very inexpensive polymer or ceramic material as the resistance element. The practical application difference between ...

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.

Thermistor temperature sensors are less expensive, more durable, typically provide a more accurate range of temperature measurement, and can much more rapidly change their resistance in line with temperature fluctuations, than RTDs. However, their temperature measurement ranges are much lower than RTDs, and the correlation of their resistance to temperature change is non-linear. Resolving this ...

Thermistors in Single Supply Temperature Sensing Circuits

Although the temperature range of the thermistor is a little better than the diode or silicon-based temperature sensor ( −55°C to +175°C), it is still limited to a practical range of −100°C to +175°C. This can also be compared to the temperature sensing range of the RTD (−200°C to 600°C) or the thermocouple which ranges up to 1820°C. The advantages versus disadvantages of the ther ...

Capgo - Thermistor Temperature Sensors

A problem with the thermistor is the varying measured temperature resolution that is achieved over the temperature range. Usually the resolution is good at lower temperatures, but poor at higher temperatures. If the measuring device has a single scale, this can be an irritating characteristic. One way to simply fix this problem is to connect a resistor in parallel with the thermistor. The ...
