Tube skin thermocouple and resistance temperature detector_R600 series_R601, R602, R611, R612

Type: R601, R602, R611, R612


Service intended


This tube skin temperature sensor is designed to measure the surface temperature of a pipe or a tube used in a boiler, a furnace, a heat exchanger, and a reactor. It is constructed to resist against high temperature and a corrosive agents by tightly attaching the sensor to the measuring area by welding a knife edge pad or a plate weld pad.


Furthermore, to protect the pad and the sheath from the heat expansion, it employs a coil shaped design.
