Our Flexible Thermocouple Extension Cable Type B with ceramic yarn insulation is designed for precision and toughness in extreme heat. Built to connect Type B thermocouples (platinum-rhodium alloy) to your measurement systems, this cable delivers accurate temperature readings up to 260°C. The ceramic yarn insulation is flame-resistant and super durable, while the stranded conductors and stainless steel overbraid make it flexible enough to snake through tight spaces without breaking a sweat. Rated for 300V and available with optional aluminum Mylar shielding, it keeps signals clean even in noisy environments. It’s the go-to choice for high-temperature applications where reliability can’t be compromised.
The thermocouple extension cable market is heating up, driven by growth in industries like aerospace, metallurgy, and glass manufacturing. With industrial processes pushing higher temperatures, there’s a rising demand for cables that can handle extreme heat while staying flexible and safe. Ceramic yarn insulation is gaining traction for its superior thermal resistance compared to traditional materials like fiberglass or silicone. Plus, as automation and precision monitoring become standard, low-noise cables with shielding are critical. Our Type B cable aligns perfectly with these trends, meeting IEC 60584-3 and ANSI MC96.1 standards while offering unmatched flexibility and durability.
