Description
Thermocouple with N-U-N (Nipple-Union-Nipple) Connection is a heavy-duty industrial temperature sensor engineered for high-temperature process monitoring where long insertion lengths and easy maintenance are essential. Equipped with a K-Type (Chromel-Alumel) sensing element, this thermocouple accurately measures temperatures from 0°C to 1200°C, making it ideal for furnaces, boilers, reactors, pressure vessels, petrochemical plants, and other demanding industrial applications.
Its defining feature is the Nipple-Union-Nipple (N-U-N) process connection, which allows technicians to disconnect and replace the thermocouple at the union without disturbing the process-side threaded connection. This significantly reduces maintenance time, minimizes thread wear, and helps avoid unnecessary process shutdowns during calibration or sensor replacement.
The 1250 mm insertion length makes the AKFS-10 particularly suitable for tall furnaces, deep process vessels, long ducts, boilers, and large reactors, where standard thermocouples cannot reach the desired sensing point. Its SS310 stainless steel protection sheath offers excellent resistance to oxidation, thermal shock, and high-temperature corrosion, ensuring reliable operation in continuous industrial service.
For hazardous locations, the thermocouple is fitted with a flameproof die-cast aluminium terminal head featuring an IP67 protection rating and double cable entry, providing secure wiring, environmental protection, and compliance with demanding industrial installations. An optional spring-loaded terminal assembly is also available for applications involving vibration or mechanical movement.
