ABSTRACT:
A multipoint thermocouple assembly for monitoring temperatures at various locations in a utilization environment includes an elongate thermocouple support strap insertable lengthwise into a protective hollow well or the like. Mounted on the support strap are a plurality of thermocouples which are generally held against longitudinal movement relative to the support strap but the respective measuring junctions thereof are supported by respective camming members connected to a common cable for simultaneous longitudinal movement of the camming members relative to the support strap for urging the measuring junctions outwardly into thermally conductive engagement with respective wall portions of the well. The support strap and actuation cable are laterally flexible so that the assembly may be coiled for ease in fabrication, installation and shipping. Each camming member includes an outwardly angled guide tube having opposed camming surfaces operative respectively to force the respective measuring junction outwardly and inwardly upon movement of the actuation cable in opposite directions. During insertion of the assembly into the well or during withdrawal therefrom, the measuring junctions are held out of contact with the inside wall of the well for ease of insertion and removal of the entire assembly from the well without damage to the measuring junctions. Only after full insertion of the assembly into the well are the measuring junctions mechanically and controllably loaded or tensioned against the inside wall of the well. The invention also relates to a multipoint thermocouple assembly/well combination and its method of assembly.
