Core Functional Technology of Thermocouples and Temperature Probes
Thermocouples
1. **Principle of Operation**:
- Thermocouples utilize the Seebeck effect, where a voltage is generated at the junction of two dissimilar metals when there is a temperature gradient. This voltage is directly proportional to the temperature difference between the measurement junction and a reference junction, allowing for accurate temperature readings.

Temperature Probes
1. **Types**:
- **RTDs (Resistance Temperature Detectors)**: Utilize the predictable change in resistance of metals (commonly platinum) with temperature changes, offering high accuracy and stability.
- **Thermistors**: Temperature-sensitive resistors that exhibit a significant change in resistance with temperature, typically used in limited temperature ranges.
- **Infrared Sensors**: Measure temperature from a distance by detecting infrared radiation emitted by objects, useful for non-contact measurements.
Application Development Cases
Conclusion
Thermocouples and temperature probes are critical components in a wide array of applications, providing essential temperature measurement capabilities. The integration of timing and control devices like the MM74HC221AN can enhance these systems, enabling precise monitoring and response functions. Understanding the core technologies and their applications can lead to more effective designs and implementations in temperature measurement systems, ultimately improving efficiency and safety across various industries.
