Overview
CHANGLONG NCW2-75 reversible temperature measuring patch has a unique discoloration temperature display, digital display and reversible function of the changed Color, and has its own sticker. 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 black to red, and the number of over-temperature at the place is displayed on the temperature measuring patch. It is easy to find the temperature rise of the temperature monitoring part during the inspection, so as to find out the hidden trouble and prevent the occurrence of accidents. If the temperature of the temperature monitoring part is too high, the temperature measuring patch will immediately be over-heated and discoloration. After chilling down, the temperature measuring patch will immediately return to its original Color, and the patch can still be used.
Features
1. Reversible discoloration function, restore primary color after temperature reduction, repeability
2. Digital display of overtemperature temperature
3. Comes with sticker, easy to paste and install
4. Rapid discoloration Response, real-time monitoring of temperature changes
Principle
When the temperature of the monitoring site reaches or exceeds the rated temperature of the temperature measuring patch at 75 ° C, the patch immediately changes from black to red and displays the over-temperature number; when the temperature decreases, the patch will return to its original black, maintaining the repeability characteristics.
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 area to be monitored
2. Tear off the protective film on the back of the temperature measurement patch
3. Paste the patch on the part that needs to monitor the temperature
4. Regular inspection of patch Color change
Notice
• Make sure the surface of the monitoring part is clean and drying before pasting
• Avoid use in humid or corrosive environments
• Regularly check the patch status to ensure the effectiveness of monitoring
• After the patch discoloration, the temperature will decrease and the primary color will be restored, which can be used continuously
