Overview
CHANGLONG SWX-7080-4-8 railway-specific temperature patch is produced according to the China Railway Corporation TJ/CL442-2015 "Temporary technical conditions for temperature-sensing stickers for railway passenger cars Wire and cable" standard, with a unique discoloration display and digital display function, with its own sticker. When the temperature of the temperature monitoring part reaches or exceeds the rated temperature, the temperature-sensing sticker immediately changes from white to black, and the discoloration area will also display the over-temperature number. Color is irreversible after discoloration, which is convenient for inspection to find the temperature rise, find out the hidden trouble and prevent accidents.
Features
1. discoloration temperature function, the temperature reaches the rated value, that is, from white to black
2. Digital display function, display over-temperature numbers when the discoloration area is large
3. Bring your own sticker, easy to install
4. Irreversible discoloration, easy to permanently record over-temperature conditions
5. In line with railway-specific standards, suitable for railway passenger car environment
Principle
The temperature-sensing patch realizes the monitoring function through temperature-sensitive materials. When the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature-sensing patch (70 ° C or 80 ° C), the temperature-sensing patch immediately changes irreversibly from white to black, and when the discoloration area is large, the specific overtemperature number is displayed, thus intuitively indicating the temperature abnormality.
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
TJ/CL442-2015 Interim technical conditions for temperature sensitive stickers for railway passenger cars Wire and cable
Steps
1. Clean the surface of the temperature monitoring part to ensure that the drying is free of oil stains
2. Tear off the protective film on the back of the temperature-sensitive sticker.
3. Paste the temperature sticker evenly on the connection part that needs to monitor the temperature
4. Regular inspection of temperature sticker Color change
Notice
• The temperature sticker is irreversible after discoloration and needs to be replaced in time
• Make sure the surface is clean and drying before pasting to ensure firm pasting
It is only used for temperature monitoring and cannot be used as an accurate temperature measuring instrument
• Avoid high temperature and humid environment when storing
• Sold as a whole sheet, each sheet contains 30 pieces, and can be used on demand when in use
