K-Type Surface-mount thermocouple with 0-600℃
Working Principle
The K-type thermocouple is based on the Seebeck effect, which states that when the junctions of two different metals are at different temperatures, a potential difference will be generated between them. A K-type thermocouple consists of a nickel-chromium alloy (positive) and a nickel-aluminum alloy (negative). When there is a temperature difference between the hot and cold junctions, a thermoelectric voltage is generated in the circuit, and the temperature can be inferred by measuring this voltage difference.
Product Features
1. Easy installation: Comes with self-adhesive backing, allowing it to be directly attached to the surface of the object being measured without the need for complex tools or processes, enabling quick installation.
2. Fast response: Due to its ultra-thin structure and good thermal conductivity, it can quickly sense temperature changes, with a short thermal response time, accurately reflecting the temperature variations of the measured object in a timely manner.
3. High flexibility: Can be bent to adapt to surfaces of various shapes, and can also reach narrow spaces for temperature measurement.
4. High accuracy: Accuracy level can reach Grade 1, meeting the needs of most industrial and laboratory temperature measurements.
