DENSO provides two types of oxygen sensors: a planar type and a thimble type.
Benefits and Features
- Quick activation of zirconia solid electrolyte
- DENSO’s planar type oxygen sensor has a zirconia solid electrolyte integrated with an alumina heater substrate, allowing it to more quickly detect oxygen concentration with a light-off time of 10 seconds.
- High-detection accuracy
- Controls porosity and surface conditions of a platinum detection electrode resulting in high accuracy detection.
- Short response time and high reliability
- The sensor cover has a unique water-resistant structure that smoothly introduces exhaust gas without allowing water to invade, achieving short response time and high reliability.
