Abstract:
1. A temperature sensor comprising: a wire comprising a resistance temperature detector (RTD) sensing material wrapped in a plurality of adjacent windings around a flexible core wire to form distributed adjacent windings insulated from the core wire and including separation between adjacent windings to form a flexible assembly, the wire including a first end and a second end and the core wire including a first core end and a second core end, the first end electrically connected to the first core end, the second core end providing a first lead; an insulated lead wire electrically connected to the second end of the wire to provide a second lead; a first layer of heat shrinkable tubing encapsulating at least the first end and the first core end; and a second layer of heat shrinkable tubing covering at least a portion of the first lead and second lead, wherein the first layer extends beyond the second layer.
