Overview
CHANGLONG ZCW4-75 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, with its own sticker. Once the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature measuring patch, the patch immediately turns from white to red and displays the over-temperature number, which is convenient for detecting the temperature rise, identifying hidden dangers and preventing accidents.
Features
1. With discoloration temperature display, digital display function
2. Color change is reversible and has recording function
3. Bring your own sticker for easy pasting
4. Three Color Changes of White to Red and Red to Black
5. Can be used repeatedly
Principle
When the temperature of the temperature monitoring part reaches or exceeds the rated temperature, the temperature measuring patch changes from white to red; when the temperature drops below the rated temperature, it changes from red to black, indicating that the rated temperature has been reached; when the temperature reaches or exceeds the rated temperature again, it changes from black to red; when the temperature drops, it changes from red to black, and so on.
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 measuring patch on the part that needs to monitor the temperature
2. Observe the Patch Color Change During Inspection
3. Color turns red to indicate overtemperature
4. Color changes to black to indicate that the temperature has reached the rated temperature and has now dropped
