二、中型和高级别分类

Temperature sensors can be categorized based on their operating principles and material compositions. These categories include:

Thermocouples: Utilizing the Seebeck effect to generate a voltage difference between two dissimilar metals or semiconductors.

Thermistors: Leveraging the NTC (Negative Temperature Coefficient) or PTC (Positive Temperature Coefficient) characteristics of semiconducting materials.

Resistance temperature detectors (RTDs): Employing the variation in electrical resistance with temperature in metallic conductors.

Infrared thermometers: Capturing thermal radiation emitted by objects to determine their surface temperatures.

三、高度可靠性指标

The performance indicators for temperature sensors encompass a range of parameters that ensure accurate measurements under various conditions:

Measurement range: The scope of temperatures that can be detected by the sensor.

Accuracy: Deviation from actual values expressed as a percentage or degrees Celsius/degree Fahrenheit.

Response time: Time elapsed between temperature changes and stabilized output signals.

Stability: Consistency in output signals over extended periods or multiple measurements.

Linearity: Degree to which output signals directly correlate with measured temperatures without significant deviation from linearity.

6.Detection limit (or resolution): Minimum incremental change in temperature detectable by the sensor.
