Low Voltage Temperature Measurement Patch

Low-temperature measurement patches are based on the principle that thermosensitive materials change their resistance or color with temperature variations. By adhering to the surface of an object, they enable temperature monitoring. They are used for checking the operational status of equipment and tracking process temperatures, commonly applied in on-site temperature measurement for electronic components, pipelines, or mechanical parts.
Selection
When selecting, consider that the temperature measurement range should cover the target operating conditions, the accuracy should meet practical needs, the patch size should match the measured surface, the response time should adapt to the rate of change, pay attention to the temperature resistance and adhesion strength of the adhesive, and ensure that the environmental factors such as humidity or corrosiveness correspond to the appropriate protection type.
