Research on High-Precision Temperature Measurement System for Ship Engines Based on Thermocouple Sensors

This paper explores a high-precision temperature measurement system for ship engines utilizing thermocouple sensors, addressing deficiencies in precision and response speed present in current technologies. By integrating an optimized sensor arrangement with advanced data processing algorithms, this system delivers stable and accurate temperature monitoring in extreme conditions. The study employs the Omega KMQSS-125U-12 type K thermocouple, paired with the AD8495 precision amplifier and a high-accuracy ADC for data collection and signal conditioning. Results indicate that the system significantly enhances the accuracy and timeliness of temperature monitoring, thereby improving data reliability and stability. Moreover, the system's design incorporates scalability and safety considerations, and utilizes ECharts for data visualization, enhancing user interaction and operational convenience. The development of this technology not only advances technical progress in the field of marine engineering but also provides valuable insights for similar applications.
