A thermocouple sensing structure for measurement of a temperature distribution inside of a vessel () filled fully or partially with multi-phase fluid consisting of residue oil, hydrogen, cracked oil/gas products, sulfur, catalyst particles or catalyst droplets, etc., the thermocouple sensing structure consists of a support structure () and a number of thermocouple sensing elements (), the thermocouple sensing elements () are partially or fully covered by the support structure (), and wherein the closed tip (B,C,D,M) of the thermocouple sensing element () is passed through the support structure () to the inside of the vessel (). And a support structure () for fixation of a thermocouple sensing element () in a vessel (), in particular suitable for use in thermocouple sensing structure, the support structure () has a protection portion for protection of at least a lower portion of at least one thermocouple sensing element () relative to an upward flow direction of a fluid in the vessel (). The static pressure of the fluid in the vessel () is beard by a sheath of the thermocouple such that a requirement for the strength and shape of the support structure () is significantly decreased. Therefore, the effect on the fluid flow field in the vessel () and the fluid hydraulic resistance of the temperature measurement system are reduced to a minimum level.
