Abstract: A pressure containment assembly for use with a plurality of sensor assemblies for monitoring a parameter within a pressure vessel is disclosed. The pressure containment assembly includes a primary seal plate to seal against pressure in the pressure vessel and a plurality of passageways to receive the sensor assemblies. The containment assembly also includes a secondary seal cap connected to the process plate and covering the passageways. The seal cap includes a recessed region that is oriented such that, when the seal cap is sealed to the primary seal plate, the recessed region creates a sealed pressure containment chamber.

Abstract: A temperature sensing assembly includes first and second temperature sensors disposed within an elongate mineral insulated conductive sheath. A junction point of the first temperature sensor is electrically connected to the conductive sheath. The second temperature sensor is electrically isolated from the conductive sheath. Measurements obtained from the electrically isolated temperature sensor can be used to test insulation resistance of the assembly or temperature indications from the electrically isolated temperature sensor can be compared to measurements taken from the electrically connected junction point to take a variety of corrective actions during use of the temperature sensing assembly, such as adjusting the installation of the assembly or applying correction factors to measurements obtained from one of the temperature sensors.

Abstract: A temperature sensing assembly for measuring the temperature of an inner wall of a high temperature vessel includes a thermocouple assembly having multiple junction points to provide indications of temperature. The assembly further includes support structures for supporting the thermocouple assembly in the interior space of the vessel and to maintain the junction points proximate the inner wall of the vessel.

Abstract: A temperature sensing assembly for measuring the temperature of a surface of a structure includes a thermocouple device having a sheath containing a pair of conductors of dissimilar materials connected at a junction point to provide indications of temperature. The assembly further includes a docking device with a recess formed in a top surface to receive a portion of the sheath that is proximate the junction point. The bottom surface of the docking device is attached to the surface of the structure. The recess extends through the bottom surface of the docking device so that when the thermocouple device is positioned in the recess, the junction point is adjacent the surface of the tube. A heat shield can be attached to the docking device to shield the sheath proximate the junction point from direct and radiant heat sources.
