FAQ about Temperature Sensors - NTC Thermistors
-
1. What are NTC and PTC temperature sensors?
Both NTC and PTC temperature sensors are thermistors, and their main differences lie in the temperature coefficient and the change characteristics of resistance value with temperature.
Working principle and materials
NTC temperature sensor: Based on the temperature characteristics of semiconductor materials, its core material is usually one or more layers of ceramic materials, with the main components being metal oxides such as manganese, cobalt, nickel and copper. When the temperature increases, the electronic activity inside the conductive material increases, causing the resistance value to decrease, showing a negative temperature coefficient characteristic.
PTC temperature sensor: It is a thermistor whose core is a polymer material (such as polymer ceramic). When an electric current passes through it, the material generates heat, which increases the resistance. When the current decreases, the resistance value decreases. Therefore, by measuring the change in resistance value, the change in temperature can be calculated, showing a positive temperature coefficient characteristic. -
2. What is the difference between NTC thermistor and thermistor?
There are significant differences between thermistors and temperature sensors in terms of technical principles, performance characteristics, and application scenarios.
Technical principles
Thermistor: The thermistor is a special type of resistor whose resistance changes with temperature. According to the characteristics of resistance value changing with temperature, thermistors can be divided into two types: positive temperature coefficient (PTC) and negative temperature coefficient (NTC). The resistance value of PTC thermistor increases as the temperature increases, while the resistance value of NTC thermistor decreases as the temperature increases.
Temperature sensor: A temperature sensor is usually an active semiconductor device that outputs a voltage or current value proportional to temperature. This type of sensor usually works based on the principle of thermoelectric effect, resistive effect or thermal induction, and has built-in signal conditioning circuit and temperature compensation function, which can provide accurate and linear temperature measurement over a wide temperature range. -
3. Which is more accurate, RTD or thermistor?
Thermistor: Thermistor has higher accuracy and is usually more accurate than RTD. Its temperature coefficient is more than 10 to 100 times larger than that of metal, and it can detect temperature changes of 10^-6℃1. However, the thermistor's accuracy is limited by its operating temperature range, which is typically a maximum of 100 or 200°C.
RTD: RTD has relatively low accuracy, but its temperature measurement range is wider and it can measure over a wider temperature range. RTD has high accuracy and stability and is suitable for use in applications requiring high reliability and stability.
