Overview
CHANGLONG ZCW3-75 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, the discoloration temperature measuring patch immediately turns from white to red, and the over-temperature number of the place is displayed on the temperature measuring patch. It is easy for people to find the temperature rise of the temperature monitoring part during inspection, so as to find out the hidden dangers and prevent accidents.
Features
1. Three-color discoloration temperature measuring patch, with discoloration temperature display and digital display function
2. Color reversible and recording function
3. With its own sticker, easy to paste
4. When the temperature reaches or exceeds the rated temperature, it immediately turns from white to red and displays the overtemperature number
5. Color changes are reversible when the temperature drops, from red to black, indicating that the rated temperature has been reached
6. Can be used repeatedly, three Color changes of white to red, red to black
Principle
When the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the smart discoloration temperature measuring patch, the temperature measuring patch immediately overheats the temperature discoloration, turning from white to red; when the temperature falls below the rated temperature, the temperature measuring patch turns black, indicating that the place has been to the rated temperature; when the temperature reaches or exceeds the rated temperature again, the temperature measuring patch turns from black to red; when the temperature falls, it turns from red to black, and so on. The patch can change from white to red, red to black in three Color changes.
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. Paste the temperature measurement patch on the temperature monitoring part that needs to monitor the temperature
2. Observe the Color Change of Temperature Patch
3. When the patch changes from white to red, it indicates that the temperature reaches or exceeds the rated temperature
4. When the patch changes from red to black, it indicates that the temperature has fallen back below the rated temperature
5. The patch can be used repeatedly to continue monitoring temperature changes
