Claims (1)
- 被測ガスの流路途中に取付けられるケーシングと、
該ケーシングに設けられ前記流路内を流れる被測ガス中の酸素濃度を検出する酸素濃度検出素子と、
有蓋筒状に形成され、該酸素濃度検出素子を覆う内側プロテクタと、
該内側プロテクタの筒部を径方向外側から取囲んで設けられ、前記筒部との間にガス通路を画成する筒状の外側プロテクタとを備え、
前記内側プロテクタの筒部は、前記酸素濃度検出素子の外周側と前記内側プロテクタの内周側との間で径方向の隙間(Sa)をもって対向し、
該径方向の隙間(Sa)は、前記酸素濃度検出素子との間で全周にわたって径方向の寸法が等しくなるように構成し、
前記径方向の隙間(Sa)は、前記ガス通路の径方向寸法(Sb)よりも全周にわたって小さくなるように構成してなる酸素センサ。
