Overview
CHANGLONG SWX-70-3-8 railway special temperature sticker is produced according to China Railway Corporation TJ/CL442-2015 "Temporary technical conditions for temperature stickers for railway passenger cars Wire and cable" standard, with unique discoloration temperature display, digital display function, with its own sticker. Once the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature sensing sticker, the temperature sensing sticker immediately turns from white to black, and the temperature sensing sticker with a large discoloration area will also display the over-temperature number. Due to the irreversible color after over-temperature discoloration, it is easy to be found in the inspection of the temperature monitoring part of the temperature rise, so as to find out the hidden trouble and prevent the occurrence of accidents.
Features
1. With unique discoloration temperature display function
2. With digital display function
3. With its own sticker
4. Color irreversible after over-temperature discoloration
5. Production according to railway-specific standards
Principle
When the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature-sensing sticker by 70 ° C, the temperature-sensing sticker immediately changes from white to black, and the temperature-sensing sticker with a large discoloration area will also display the over-temperature number there. Since the color is irreversible after discoloration, it is convenient for inspectors to detect temperature abnormalities in time.
