Abstract:
A monitor for sensing respective temperatures at a plurality of points at least a first one of which is separated by a distance having a finite constituent in a predetermined direction from at least one other point, said monitor comprising:(a) first elongated supporting structure having a leading end and a trailing end, (b) a first sensor mounted on the leading end of said first elongated supporting structure, (c) second elongated supporting structure having a leading end and a trailing end, (d) a second sensor mounted on the leading end of said second elongated supporting structure, (e) third elongated supporting structure having a leading end and a trailing end, (f) a third sensor mounted in the leading end of said third elongated supporting structure, (g) a first pair of scissor arms pivotally linking said first elongated supporting structure to said second elongated supporting structure to maintain parallelism between them, (h) a second pair of scissor arms pivotally linking said second elongated supporting structure to said third elongated supporting structure to maintain parallelism between them, and (i) means for guiding respective ones of said leading means along scissor arms to form an orderly group exiting said monitor, wherein the first, second and third sensors each comprise a structural housing of temperature-resistant material characterized by appreciable thickness in said predetermined direction, a first thermocouple mounted at a respective first location on said structural housing for sensing temperature at a respective first point, a second thermocouple mounted at a respective second location on said structural housing and separated from said respective first location by a distance having a finite constituent in said predetermined direction for sensing temperature at a respective other point, and means for leading respective signals from said respective first and second thermocouples to recording instrumentation.
