CONTACT COMBUSTION TYPE GAS SENSOR, DETECTION ELEMENT STRUCTURE OF CONTACT COMBUSTION TYPE GAS SENSOR, AND MANUFACTURING METHOD FOR DETECTION ELEMENT OF CONTACT COMBUSTION TYPE GAS SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a contact combustion type gas sensor which can prevent in advance uneven heating in sintering, be used immediately after being manufactured, and suppress manufacturing cost, a detection element structure of the contact combustion type gas sensor, and a manufacturing method for a detection element of the contact combustion type gas sensor.;SOLUTION: There is provided a contact combustion type gas sensor X comprising a detection element 10 sensing a detected gas and a compensation element 20. The detection element 10 includes: a noble metal wire 11 including a coil part 11a formed in a coil shape; and a combustion catalyst part 12 formed by coating the coil part 11a with an insulative metal oxide carrier carrying a catalyst composed of noble metal active to the detected gas and performing sinter molding. The metal oxide is sintered in a heating furnace by being heated by the heating furnace.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
