Gas sensor
Document Type and Number:
Japanese Patent JP6350359
Kind Code:
B2
Abstract:
A sensor structural body, which is formed by stacking a sensor element and a heater, has a sensor protruding portion that protrudes distalward from a holder. The sensor element includes a solid electrolyte body, a measured-gas space, a reference-gas space, a pump cell, a monitor cell and a sensor cell. A heat-generating portion of the heater is entirely arranged in the sensor protruding portion. The length L (in mm) of a formation region of the heat-generating portion and the length H (in mm) of the sensor protruding portion in a longitudinal direction, in which the sensor protruding portion protrudes from the holder, are set to be in a range that is enclosed by first to fourth reference lines X1, X2, X3 and X4 on a two-dimensional coordinate plane whose horizontal and vertical axes respectively indicate the lengths L and H. The first to the fourth reference lines X1-X4 respectively represent the relationships of H=L, H=20, H=−4.24L+42.71 and H=−4.24L+68.6.
