Abstract: A thermocouple sensing structure for measurement of a temperature distribution inside of a vessel (10) 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 (1) and a number of thermocouple sensing elements (3), the thermocouple sensing elements (3) are partially or fully covered by the support structure (1), and wherein the closed tip (3B,3C,3D,3M) of the thermocouple sensing element (3) is passed through the support structure (1) to the inside of the vessel (10). And a support structure (1) for fixation of a thermocouple sensing element (3) in a vessel (10), in particular suitable for use in thermocouple sensing structure, the support structure (1) has a protection portion for protection of at least a lower portion of at least one thermocouple sensing element (3) relative to an upward flow direction of a fluid in the vessel (10).

Abstract: A pressure measuring instrument having a sensor carrier, a casing, a plug connector, evaluation electronics, and a pressure sensor. The sensor carrier supports the pressure sensor adapted to output a pressure-proportional, electrically detectable pressure signal. The sensor carrier has a base body, a pressure terminal formed together with the base body to be connected to the source of the pressure to be detected, and a seat having several different circle geometries, each having an annular surface adapted for mounting a pressure sensor. The pressure terminal has a connecting channel opening inside the seat, and the annular surfaces of the individual circle geometries are axially staggered with respect to the port of the connecting channel, wherein the annular surface having the smallest diameter is closest to the connecting channel port.
