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.
Claims18
A platinum temperature sensor comprising:
- a plurality of stacked plate-type ceramic sheets;
- platinum resistance patterns provided on surfaces of respective said ceramic sheets, each of said platinum resistance patterns having a plurality of bent portions and thereby having a nonlinear configuration;
- and
- connecting means for connecting adjacent ones of said platinum resistance patterns with each other;
- wherein an outermost one of said ceramic sheets has through holes communicating with an outermost one of said platinum resistance patterns, which is located adjacent said outermost ceramic sheet.
A method of manufacturing a platinum temperature for comprising the steps of:
- applying platinum resistance patterns to respective surfaces of a plurality of ceramic sheets, each of said patterns having a plurality of bent portions and thereby having a nonlinear configuration;
- stacking said plurality of ceramic sheets;
- interconnecting adjacent ones of said platinum resistance patterns on respective ones of said ceramic sheets;
- and
- providing through holes in an outermost one of said ceramic sheets, said through holes communicating with an outermost one of said platinum resistance patterns which is located adjacent said outermost ceramic sheet.
