New Temperature Sensor Label Offers Irreversible Color Change for Accurate Heat Monitoring
By hqt
Keeping track of temperature is important in many industries. Now, a new type of temperature sensor label makes this easier and safer. This label can show changes in temperature with a simple color shift. When the surface it monitors gets too hot, the label changes from white to black.

The color change is permanent. This means the label keeps a record of the overheating event. You can check it later, even if the object cools down. Each label has several temperature points. These points are set to different levels, like the steps on a ladder. As the temperature rises, the points darken one by one.
This smart design works like a thermometer you can stick onto equipment. It is simple, quick, and does not need batteries or special tools. Industries like food storage, electronics, and healthcare can all benefit from this. It helps prevent accidents caused by unnoticed overheating. The new temperature sensor label is small but powerful. It turns invisible risks into clear, visible signs. That’s a big step forward for safety and quality control.
What Is a Temperature Measurement Sticker?
A Unique Color-Changing Tool
Temperature measurement stickers are simple yet highly effective. They are small, lightweight, and easy to apply. When the surface temperature of an object exceeds a specific threshold, the sticker immediately changes color. Typically, the color change goes from white to black. This reaction is clear, visible, and requires no equipment to interpret. Users can instantly tell if overheating has occurred just by looking.
These stickers offer a practical solution for industries where real-time monitoring is essential but where electronic sensors may not be practical or cost-effective. Their simplicity allows them to be used even in harsh or remote environments.
Step-by-Step Temperature Points
Each temperature measurement sticker includes multiple temperature points. These points are set to different levels, arranged in order from lower to higher temperatures. As the temperature rises, each point turns black one after another.
This stepwise color change allows users to see not just if overheating happened, but how much the temperature rose. It acts like a historical record of the object’s heat exposure over time. This layered approach improves the accuracy of temperature monitoring and helps guide maintenance or safety decisions.
How It Works Like a Thermometer
Temperature measurement stickers perform like traditional thermometers in many ways. They visually show when temperatures cross critical thresholds. But unlike glass thermometers or digital sensors, they require no batteries, no maintenance, and no calibration.
Their passive, automatic function makes them ideal for continuous temperature monitoring. In fields where even a short delay in detection could cause major problems, these stickers provide an immediate, reliable signal that action is needed.
Key Features of the Temperature Sensor Label
Permanent Color Change
One of the most important features of these stickers is their irreversible color change. Once a part of the sticker turns black, it will never return to white, even if the temperature drops.
This permanent mark acts like a built-in recorder, proving that overheating occurred. It eliminates guesswork and helps ensure accurate reporting, inspections, and audits.
High Sensitivity and Accuracy
Crystal Code’s temperature sensor labels are designed with precision. They react quickly once the preset temperature is reached. Even small fluctuations around the threshold temperature can trigger the change.

This high sensitivity helps industries detect potential risks early. Early detection leads to faster response times, fewer failures, and better overall system safety.
Easy to Use on Any Surface
The stickers are made from soft, flexible materials. They can easily conform to flat, curved, or textured surfaces. Applying them is simple – just peel off the backing and press the sticker into place. No special training, tools, or setup is needed.
This ease of use means the stickers can be applied in a wide range of environments. From busy production lines to outdoor equipment, these stickers offer dependable performance anywhere they are needed.
Common Applications of Temperature Stickers
Railways and Train Monitoring
In railways, the sticker monitors the temperature of wheel axle boxes. Overheating axle boxes can cause serious accidents. These stickers give early warnings and help improve safety.
Electrical Equipment Safety
Temperature stickers are placed on busbars, circuit breakers, and transformers. They help detect abnormal heating before it leads to equipment failure or fire.
Steel Mills and Heavy Industry
Heavy industries use them on machinery and furnace parts. Workers can quickly identify overheating parts without touching hot surfaces, improving both safety and maintenance efficiency.
