1. Does the temperature of the object being measured need to be recorded, alarmed, and automatically controlled? Does it need to be measured and transmitted over long distances?
2. Temperature measurement range and accuracy requirements;
3. Is the size of the temperature sensing element appropriate?
4. In situations where the temperature of the object being measured changes over time, can the hysteresis of the temperature sensing element meet the temperature measurement requirements?
5. Whether the environmental conditions of the object being measured will damage the temperature sensing element;
6. Price guarantee and ease of use.
Temperature sensors indirectly measure temperature by observing how an object changes its properties with temperature. Many materials and components exhibit temperature-dependent properties, making them suitable for temperature sensors. The physical parameters of a temperature sensor that change with temperature include: expansion, resistance, capacitance, electromotive force, magnetic properties, frequency, optical characteristics, and thermal noise. As production advances, new types of temperature sensors will continue to emerge.
