1. Sensing materials
The core of the temperature sensing harness lies in its sensing materials. Currently, commonly used temperature sensing materials include Shibaura thermistors (NTC/PTC), thermocouples and fiber optic sensors.

Shibaura thermistors (NTC/PTC): The resistance value of NTC (negative temperature coefficient) thermistors decreases as the temperature increases. The opposite is true for PTC (positive temperature coefficient) 서미스터. By measuring the change in resistance, temperature information can be accurately obtained. These materials have high sensitivity and a wide temperature measurement range, but their application is limited by environmental conditions and resistance stability.

열전대: It is composed of two different metal wires and generates a voltage signal through the thermoelectric effect. Thermocouples have a wide temperature range and high stability, but their signal processing is complex and requires precise calibration and compensation.

Fiber optic sensor: Fiber-optic temperature sensing technology detects temperature by monitoring changes in light. This sensor has high sensitivity and anti-interference ability, and is suitable for temperature monitoring in harsh environments.

2. Signal processing technology
The signal processing technology of the sensor temperature sensing harness includes two parts: analog signal conversion and digital signal processing.

Analog signal conversion: The signal output by the sensor is usually an analog signal, which needs to be converted into a digital signal through an analog-to-digital converter (ADC). During the analog signal conversion process, issues such as noise suppression, signal amplification and filtering need to be considered to ensure the accuracy and stability of the signal.

Digital signal processing: Digital signal processing technology can further analyze and process the digital signal output by the sensor. 예를 들어, algorithms are used for temperature compensation, error correction and data smoothing. Modern temperature sensing harnesses often integrate microprocessors or microcontrollers to implement complex signal processing and data analysis functions through software.

3. Integrated design
The integrated design of temperature sensing harnesses involves comprehensive consideration of sensors, signal processing units, and connecting harnesses.

Sensor integration: Embedding the sensor module into the harness can achieve space savings and compact system design. The layout of the sensor needs to consider the accuracy and response speed of temperature measurement, while ensuring the mechanical strength and durability of the harness.

Signal transmission: In terms of signal transmission, it is necessary to select appropriate wires and connectors to reduce signal attenuation and interference. High-quality shielding and insulation materials can improve the stability of signal transmission.

System integration: Modern temperature sensing harnesses often need to be integrated with other electronic systems, including communication interfaces, data storage, and processing units. System integration design needs to consider compatibility, reliability, and scalability to meet the needs of different application scenarios.

4. Future development trends
With the advancement of science and technology, the technology of temperature sensing harnesses is also developing. Future trends include:
Intelligence: Temperature sensing harnesses will gradually develop towards intelligence, and realize self-diagnosis, adaptive adjustment, and remote monitoring functions by integrating more sensors and processing units.
소형화: With the miniaturization of electronic components, the size of temperature sensing harnesses will become smaller and smaller, suitable for more compact and complex application scenarios.
High reliability: Future temperature sensing harnesses will pay more attention to reliability and durability to meet the application requirements in harsh environments, such as high temperature, high humidity and strong vibration environments.
Multifunctionality: In addition to the traditional temperature measurement function, future temperature sensing harnesses may integrate more functions. 예를 들어, humidity detection, pressure measurement, 등., to provide more comprehensive environmental monitoring capabilities.
