High-speed train temperature measurement paper

The high-speed train temperature-sensitive paper is a thermochromic material that changes color in response to temperature variations, used for monitoring the surface temperature of train components. Its principle is based on the reversible or irreversible color change of the thermosensitive coating at specific temperatures. Its function is to visually indicate overheating areas, and it is applied for temperature safety inspections in parts such as train bearings and braking systems.
Selection
When selecting temperature measurement strips for bullet trains, it is essential to consider that the temperature range should cover the operating temperatures of the components, the color-changing accuracy must meet monitoring requirements, the response time should align with actual working conditions, and the material must withstand the vibration environment of the bullet train. Additionally, it is crucial to verify that the strips comply with relevant railway industry standards and specifications.
