BK thermocouple sensors with a ceramic ø15 mm protection tube are ideal for high temperatures and applications, where steel tubes erode quickly. Constant maximum temperature 1000°C, instantaneous maximum temperature 1200°C. Clamp assembly 15 mm in diameter and 150 mm in length. The sheath of C610 ceramic material. Coupling with a ring.

For temperatures exceeding 1000°C we recommend the type S thermocouple, which is many times more durable than type K.
