Abstract

PURPOSE: To make operation easy and eliminate the off-centering of a thermistor element and lead wires when the protecting tube is made smaller in diameter by limiting the positions of the thermistor element and its lead wires in the protecting tube with the premolded fillers.
CONSTITUTION: A thermistor element 3 connected with lead wires 5 to its electrode terminals is contained in the first filler which has been molded of powder of heat- resistant insulator such as MgO to a mortar shape and the similar second filler 10 having a pair of through-holes. Next, these are inserted into a heat-resistant metal insulation tube 1, and an outer tube 2 likewise composed of heat-resisting alloy is inserted onto this tube 1. Next, strong pressure is exerted to the tube 2 to reduce the diameters of the tubes 2, 1, by which the fillers 8, 10 are disintegrated to become powder 12 of the heat-resistant insulator. Thus, the element 3 and wires 5 are held in a stable state in the tube 1.
