Overview
CHANGLONG ZCW4-65 smart temperature measuring patch is a three-color discoloration temperature measuring patch with unique discoloration temperature display, digital display, and reversible and recording functions of the changed Color. Once the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature measuring patch at 65 ° C, the discoloration temperature measuring patch immediately turns from white to red, and the number of over-temperature at the place is displayed on the temperature measuring patch, which is convenient for inspection to find the temperature rise, so as to find the hidden trouble and prevent accidents.
Features
1. Intelligent discoloration temperature display function, when the temperature reaches 65 ° C, it changes from white to red, and when the temperature drops, it changes from red to black
2. Digital display of over-temperature status for easy identification
3. Color changes are reversible and can be used repeatedly
4. Comes with sticker, easy to install
5. With temperature recording function, black indicates that the rated temperature has been reached
Principle
When the temperature of the temperature monitoring part reaches or exceeds 65 ° C, the temperature measuring patch immediately turns from white to red; when the temperature drops below 65 ° C, it turns from red to black, indicating that the rated temperature has been reached; when the temperature reaches or exceeds 65 ° C again, it turns from black to red; when the temperature drops, it turns from red to black, achieving a reversible change cycle of white, red, and black.
Applications
The connection part of the bus in the substation, the connection between the bus and the equipment terminals, the contacts of the disconnector, the shell of electrical equipment such as transformers, motors, capacitors, etc
Steps
1. Clean the surface of the temperature monitoring part
2. Tear off the protective layer of the sticker on the back of the temperature measuring patch
3. Paste the temperature measurement patch evenly on the temperature monitoring part
4. Regular inspections to observe Color changes
5. When discoloration is found, deal with the hidden trouble in time
Notice
• Make sure the surface is clean and drying before pasting
• Avoid use in humid or corrosive environments
• Regularly check the patch status
• When discoloration is found, appropriate measures should be taken in a timely manner
• Pay attention to the irreversible discoloration characteristics of the patch
