How to choose the right thermistor for your temperature ...

· 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 (this is due to their low sensitivity and high resistance tolerance at temperature extremes), or2 ) calibrate once using a silicon-based linear thermistor, which is significantly more stable than ...

The useful temperature range of a thermistor is shifted by varying the sensing current. The temperature ranges for the LDT-5900, using a 10 kΩ thermistor, are shown by the horizontal

List of temperature sensors - Wikipedia

Mechanical temperature sensors. Thermometer; Therm; Electrical temperature sensors. Thermistor- Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature. Negative Temperature Coefficient (NTC) thermistors exhibit a decrease in electrical ...

Measuring Thermistors in a Half-Bridge Configuration with ...

· Thermistors are typically desirable for applications that require a very accurate temperature measurement over a narrow temperature range. Thermistors are available for temperatures between -50°C and 100°C. Many thermistors have a sensitivity of 3-6% per °C which means that they may vary in resistance by more than ±500% of their nominal value over their full measurement range…

Thermistor | Analog Devices

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 that are available in two types: those with negative temperature coefficients (NTC) and those with positive temperature coefficients (PTC). NTC thermistors ...

RTD vs. Thermocouple vs. thermistor in temperature sensors

· Typical temperature sensors used in circuits are resistance temperature devices (RTDs), thermocouples, thermistors or integrated silicon sensors. Trade-offs amongst these devices include cost, cost to operate, response time, noise immunity, operating temperature range, and stability. Stable devices will produce less output signal drift over time, which reduces the need for repeat calibrations.

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 ...
