An apparatus and method for manufacturing temperature sensitive thermocouple cable are disclosed. The method includes the steps of inserting a tamping tube within an outer metal sheath, wherein the tamping tube includes apertures positioned therein for appropriate positioning of thermocouple wires. The thermocouple wires are introduced into the apertures with the outer sheath then being filled with a powdered insulating material having a negative temperature coefficient while the tamping tube is removed. In so doing, the insulating material is compacted around the thermocouple wire and the thermocouple wires are appropriately positioned in parallel disposition within the outer sheath. The ends of the outer sheath are enclosed with rubber stoppers which also secure the ends of the thermocouple wires. The resulting assembly is then drawn to a reduced diameter and annealed as appropriate to produce a temperature sensitive cable tailored to a specific application.
