The small size of the temperature sensor is beneficial for applications with space requirements, but care must be taken to avoid self-heating errors. The temperature sensor also has its own measurement method. The small size of the temperature sensor is an advantage, it can stabilize quickly and is not easy to cause heat load. However, it is also very unstable and large currents will cause self-heating.

Since the temperature sensor is a resistive component, any current source will generate heat due to the output power on it. The power is equal to the product of the square of the current and the resistance. Therefore, a small current source should be used. If the temperature sensor is exposed to high temperature, it will cause damage.

1. Does the temperature of the measured target need to be recorded, alarmed and automatically controlled? Does it need to be accurately measured and transmitted over long distances?

2. Dimension and precision requirements for temperature measurement;

3. Is the size of the temperature measuring components appropriate?

4. In places where the temperature of the measured object changes over time, whether the obsolescence of the temperature measurement components can meet the temperature measurement requirements;

5. Whether the environmental conditions of the object being measured have any impact on the temperature measurement components;

6. Is the price guaranteed and is it convenient to use?
