Thermometer type temperature measuring paper
WDJ series temperature measuring paper has strong adhesion, easy to stick, irreversible color change after overheating, and recording function. Produced in accordance with the TJ/CL442-2015 "Interim Technical Conditions for Temperature Sensitive Stickers for Railway Passenger Car Wires and Cables" standard of China Railway Corporation, and passed the quality inspection of national authoritative institutions.
Temperature measuring paper, also known as surface temperature indicator strip, temperature test strip, temperature measuring sticker, temperature sensing sticker, etc. The WDJ series temperature measuring paper has a unique color changing and temperature indicating function, which can be used for temperature detection on the surface of objects. The temperature measuring paper is generally composed of multiple temperature points combined, with temperature points rising in steps, especially like a thermometer. Once the temperature of the monitoring part reaches or exceeds the rated temperature of the temperature measuring paper, the corresponding temperature point of the temperature measuring paper immediately changes from white to black. After the color changes irreversibly due to overheating, it has a recording function and is easy for people to detect the temperature rise of the monitoring part during inspection, thereby identifying potential faults and preventing accidents from occurring.
Temperature measuring paper is widely used in many fields such as railways, electricity, steel mills, etc., such as temperature monitoring of wheel axle boxes for various types of air-conditioned railway passenger cars, temperature monitoring of busbars and electrical equipment in power switchgear, etc. The WDJ series temperature measuring paper produced by our company also has good flexibility and strong adhesion. The temperature measuring paper itself comes with adhesive, making it very convenient to use.
Usage of thermometer type temperature measuring paper
1. The WDJ series temperature measuring paper is in the form of a label. As long as the corresponding rated temperature measuring paper is selected, it can be directly pasted on the part that needs to be monitored for temperature. The temperature measuring paper should be pasted on a clean and dry area, and firmly pressed when pasting.
2. Precautions:
a. When pasting on operating equipment, please follow the equipment operation safety regulations to ensure safety.
b. The temperature measuring paper used outdoors should be attached to a shaded and rainproof area, avoiding direct sunlight and rain to prevent accelerated aging of the paper.
Reflective temperature measuring patch
Reflective temperature measuring patches are widely used in the connection parts of substation busbars to monitor the temperature of busbar connections and electrical equipment enclosures. And the changed color has a reflective display function.
The BCW series reflective color changing temperature measuring patch has unique color changing temperature display, reflective display, and temperature recording functions. It comes with adhesive and is used at the connection part of the substation busbar. It can also be attached to the connection part between the busbar and the equipment terminal and the contact of the isolation switch. It can also be attached to the shell of electrical equipment such as transformers, capacitors, and motors 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 measurement patch, the temperature measurement patch immediately changes color and displays the number of overheating at that location on the temperature measurement patch, especially at night. The temperature measurement patch has a reflective display function. Whether it is day or night, it is easy for people to detect the temperature rise in the monitoring area during inspections, thereby identifying potential faults and preventing accidents from happening.
If the temperature monitoring area causes the temperature measuring patch to change color due to excessive temperature, and the temperature measuring patch does not return to its original white color after cooling down, it will be recorded. In order to respect the color habits developed by the substation department over the years, the reflective color changing temperature measuring patch produced by our company changes color after overheating as follows: the 60 ℃ patch changes from white to yellow, the 70 ℃ patch changes from white to green, the 80 ℃ patch changes from white to red, the 90 ℃ patch changes from white to black, and the 100 ℃ patch changes from white to blue. Overcoming the drawback of patches changing color to the same color at different rated temperatures, which can easily lead to confusion.
Method of using reflective temperature measuring patch
1. The BCW series reflective 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 bus joint, knife switch, transformer housing and other parts that need to be monitored for temperature. The temperature measurement patch should be pasted on a clean and dry area, and firmly pressed when pasting.
2. If you want to know the temperature of the monitoring area gradually rising during use, you can stick two or more color changing temperature measuring patches with different rated temperatures, or use BCW-678 or BCW-789 patches (each containing three 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. The color changing temperature measuring patch used outdoors should be attached to a shaded and rainproof area, avoiding direct sunlight and rain to prevent accelerated aging of the temperature measuring paper.
Reversible temperature measurement patch
The NCW series temperature measuring patch, 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 black to red and displays the number of overheating at that location on the temperature measuring patch. After cooling down, the temperature measuring patch immediately returns to its original color (black), that is, the color change is reversible and the patch can continue to be used.
The NCW series reversible color change temperature measurement patch has unique color change temperature display, digital display, and reversible color change 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 and 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 black 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.
If the temperature of the monitoring area is too high, the temperature measuring patch will immediately change color due to overheating. After cooling down, the temperature measuring patch will immediately restore its original color and can still be used.
The color change of reversible color changing temperature measuring patches generally changes from black to red, and other colors can also be selected (customized);
