Thermistor Performance Features
Thermistor It has the following advantages:
① High sensitivity. The temperature coefficient of resistance (α) of a thermistor is 10 to 100 times greater than that of metals; therefore, lower‑precision indicating instruments can be used.
② High resistance value. Its resistance is 1 to 4 orders of magnitude higher than that of a platinum resistance thermometer.
③ Small size and simple structure. It can be fabricated into various shapes as needed; currently, the smallest bead‑type thermistor measures as little as Φ0.2 mm and is commonly used for measuring “point” temperatures.
④ Short response time.
⑤ Low power consumption and no reference‑terminal compensation required, making it suitable for long‑distance measurement and control.
⑥ With abundant resources, low cost, and excellent chemical stability, the device’s surface is encapsulated with glass or other ceramic materials, making it suitable for harsh environments. By effectively leveraging these characteristics, it is possible to develop thermometers that offer high sensitivity, rapid response, and ease of use.
