Multipoint thermocouple assembly

摘要: A multipoint thermocouple assembly for monitoring temperatures at various locations, example, different depths in a process vessel, includes plurality of thermocouples, protective tube well having hollow interior, elongate guides the guiding respective thermocouples along interior well, and wedges axial locations urging measuring junctions into thermal transfer contact with wall well. In one form invention, may comprise plural channels on exterior surface an elongated support member, formed as by attaching fins or dividers to such surface, providing splines surface. another thin walled guide tubes are brazed welded longitudinally spaced rings. The have openings outer walls thereof points junction out through points. when inserted vessel protects while positioning them simultaneously sense temperature vessel. invention also relates methods making replacing therein.
