Overview
CHANGLONG SWX-70-6-8 railway special temperature sticker is produced according to the 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 sticker 70 ° C, the temperature sticker immediately turns from white to black, and the temperature 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, digital display function
2. With its own sticker, easy to install
3. Color irreversible after over-temperature discoloration, easy to identify
4. Produced according to railway-specific standards, suitable for railway environment
Principle
Temperature-sensitive stickers achieve temperature monitoring through temperature-sensitive materials. When the temperature of the temperature monitoring part reaches or exceeds the rated temperature of 70 ° C, the temperature-sensitive sticker immediately changes from white to black. The temperature-sensitive sticker with a large discoloration area will also display the number of overtemperature at the place. Due to the irreversible discoloration, it can display the overtemperature status for a long time.
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
2. Tear off the protective film on the back of the temperature-sensitive sticker.
3. Paste the temperature-sensing sticker on the connection part that needs to monitor the temperature
4. Regular inspection of temperature sticker Color change
Notice
• Color is irreversible after temperature discoloration
• Ensure that the surface of the temperature monitoring part is clean and drying before pasting
• Should be pasted on the connection part that needs to monitor the temperature as required
• Regular inspections to check the status of the temperature sticker
• Temperature stickers are sold as a whole sheet, each sheet contains 30 pieces
