Abstract: A platinum temperature sensor includes a sensor body formed of a cylindrically rolled plate-type ceramic sheet and a platinum resistance pattern provided on the surface of the ceramic sheet. The platinum resistance pattern is provided on the inner or outer surface of the ceramic sheet. The sensor may further include lead wires, and the ceramic sheet may have through holes for lead wires, which are conductively connected to both ends of the platinum resistance pattern. The lead wires are connected to the platinum resistance pattern. The sensor may further include resistance regulating lines provided on the outer surface of the ceramic sheet, and the ceramic sheet may have through holes reaching the intermediate portion of the platinum resistance pattern. The resistance regulating lines are connected to the platinum resistance pattern through a plurality of said through holes, and may be selectively cut to adjust the resistance of the platinum resistance pattern.

Abstract: A platinum temperature sensor has a plurality of stacked plate-type ceramic sheets, platinum resistance patterns provided on the surfaces of the respective ceramic sheets so that each of the platinum resistance patterns has a plurality of bent portions, and connecting means for connecting adjacent ones of the platinum resistance patterns with each other, the patterns being provided between the ceramic sheets. The connecting means comprises through holes provided in the ceramic sheets and metal paste members arranged in the through holes to interconnect respective ends of the platinum resistance patterns.
