Stainless Steel M8 threaded probe thermocouple temperature sensor for k type

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.

1. M8 Threaded Mount: Standard M8×1.25 (common) external thread, comes with a locking nut, can be directly screwed into the device threaded hole, ensuring stable installation; materials are mostly 304/316 stainless steel.
2. Probe Sheath: Stainless steel sheath tube (304/316/Inconel optional) to protect the internal thermocouple; common probe diameters are 3/4/5mm, with lengths of 50/100/150/200mm optional.
3. Thermocouple Junction: Type K (K thermocouple), available in exposed, grounded, and insulated junction types; grounded type responds quickly, insulated type is anti-interference.
4. Lead Wire: Glass fiber/Teflon/stainless steel braided high-temperature wire, IEC standard color coding (red positive, blue negative); can come with UT cold-pressed terminals or aviation connectors.
