Method of using reversible temperature measurement patch
1. The NCW series reversible color changing temperature measuring patch is in the form of a label. As long as an appropriate rated temperature color changing temperature measuring patch is selected, it can be directly pasted on the parts that need to be monitored for temperature, such as busbar joints, knife switches, transformer housings, etc. The temperature measurement patch should be pasted on a flat, clean, and dry surface, and should be firmly pressed when pasting.
2.If you want to know the gradual increase in temperature at the monitoring location during use, you can stick two or more color changing temperature measuring patches with different rated temperatures.
3. Precautions:
a. The pasting of color changing temperature measuring patches should be carried out when there is no power on the busbar or other temperature monitoring parts, and safety regulations must be followed. If you want to paste temperature measurement patches with electricity, you must use insulation rods of the corresponding level to assist in pasting.
b. Reversible color changing temperature measuring patches cannot be used in environments exposed to sunlight.
Intelligent temperature measurement patch
When the temperature reaches or exceeds the rated temperature of the patch, the patch immediately changes from white to red; When the temperature drops below the rated temperature, it does not return to its original white color, but turns black, indicating that the area has reached the rated temperature before and the temperature has now dropped; When the temperature reaches or exceeds the rated temperature of the temperature measuring patch again, the temperature measuring patch changes from black to red; So repeatedly. This patch can continue to be used.
The ZCW series intelligent color changing temperature measuring patch, also known as the three color color changing temperature measuring patch, has unique color changing temperature display, digital display, reversible color change and recording functions. It comes with adhesive and is used at the connection part of the indoor busbar in the substation. It can also be attached to the connection part between the busbar and the equipment terminal, as well as the contact of the isolation switch. It can also be attached to the shell of electrical equipment such as transformers, motors, capacitors, etc., to monitor the temperature of the busbar connection and the shell of electrical equipment. Once the temperature of the monitoring area reaches or exceeds the rated temperature of the temperature measuring patch, the color changing temperature measuring patch immediately changes from white to red and displays the number of overheating at that location on the temperature measuring patch. It is easy for people to detect the temperature rise in the monitoring area during inspection, thereby identifying potential faults and preventing accidents from occurring.
Color change of intelligent color changing temperature measuring patch:
When the temperature of the temperature monitoring area reaches or exceeds the rated temperature of the intelligent color changing temperature measuring patch, the temperature measuring patch immediately overturns and changes color, from white to red; When the temperature drops below the rated temperature, the temperature measuring patch does not return to its original white color, but turns black, indicating that the area has reached the rated temperature before and now the temperature has dropped below the rated temperature; When the temperature reaches or exceeds the rated temperature of the temperature measuring patch again, the temperature measuring patch changes from black to red; When the temperature drops, it changes from red to black and repeats this process. The patch can undergo three color changes: white to red and red to black. This patch can continue to be used.
What is the principle of color change for temperature sensing labels?
The color changing principle of temperature sensitive stickers is mainly based on the color change characteristics of temperature sensitive materials. This material can undergo chemical and physical changes at different temperatures, leading to changes in molecular structure and causing a change in the color of reflected light. Specifically, the color change form of temperature sensitive stickers can be low-temperature colored, high-temperature colorless, or low-temperature one color, high-temperature another color, and this change can be reversible. For example, in some temperature sensitive stickers, when the temperature reaches or exceeds a specific value, the color of the sticker will change, indicating the temperature change intuitively. This principle makes temperature sensitive stickers widely applicable in fields such as temperature monitoring and safety warning.
It should be noted that the color changing principle of temperature sensitive stickers may vary depending on the material formula and manufacturing process, but overall they are based on the color change characteristics of temperature sensitive materials. In addition, the use of temperature sensitive stickers should follow product instructions and safety regulations to ensure their accuracy and safety.
