Overview
CHANGLONG SWX-70-4-8 railway special temperature sticker is produced according to the TJ/CL442-2015 standard of China Railway Corporation. It has a unique discoloration temperature digital display function and comes with a sticker. When the temperature of the temperature monitoring part reaches or exceeds the rated temperature of 70 ° C, the temperature sticker immediately changes from white to black irreversibly. The temperature sticker with a large discoloration area will also display the over-temperature number, which is convenient for inspectors to detect the temperature rise in time, find out the hidden dangers and prevent accidents.
Features
1. With unique discoloration temperature and digital display function
2. Bring your own sticker, easy to install
3. Color irreversible after over-temperature discoloration, easy to identify
4. Meet the requirements of railway-specific technical standards
5. Whole sheet is sold, each sheet contains 40 pieces, which is economical to use
Principle
The temperature-sensing sticker realizes the temperature monitoring function through temperature-sensitive materials. When the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature-sensing sticker at 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 number of overtemperature at the place. Since the discoloration is irreversible, it can permanently display the overtemperature state.
Applications
Control cabinets, distribution cabinets, electrical integrated control cabinets, air conditioning control cabinets, power conversion boxes, lighting control boxes, circuit breakers, contactors, thermal relays, fuses, etc. of various types of air-conditioned passenger cars (including high-speed rail, high-speed trains, subways) and Wire and cable connection parts
Standards
China Railway Corporation TJ/CL442-2015 Interim Technical Conditions for Temperature Sensing Stickers for Wire and cable of Railway Passenger Cars
Steps
1. Remove the temperature sticker from the sticker protective film
2. Paste it on the connection part that needs to monitor the temperature.
3. Regular inspection of temperature sticker Color change
4. Immediate action when discoloration is detected
Notice
• Color is irreversible after temperature discoloration
• Make sure the surface of the monitoring part is clean and drying before pasting
• Avoid use in humid and oily environments
• Regular inspections to check the status of the temperature sticker
• If discoloration is found, the hidden trouble should be dealt with in time
