In industrial automation and process control, accurate temperature measurement is critical to ensuring product quality, operational safety, and energy efficiency. Whether you are managing a chemical processing plant, food production lines, or high-temperature metallurgy furnaces, selecting the correct sensor can mean the difference between seamless operations and catastrophic downtime. When it comes to electronic temperature measurement, two heavyweights dominate the market: Resistance Temperature Detectors (RTDs) and Thermocouples. While both serve the same ultimate purpose, their underlying technologies, performance characteristics, and ideal environments are entirely distinct. This comprehensive technical guide by Starlight Sensor breaks down the core differences to help you
