使用氧化锆固体电解质的极限电流型氧传感器已经被开发并用于许多应用。该传感器具有一些优异的特性，如寿命长、无参考气体、结构紧凑且免维护。但在实际应用中还存在一些问题。为了实现高性能的氧传感器，已经进行了一些改进。改进的主要项目是响应时间、抗振性、防水性和寿命。本文详细介绍了该传感器的改进项目和特点。结果，实现了高性能氧传感器，该氧传感器具有小于5 s的快速响应时间、对± 30 g的高抗振性、防水性和即使在高氧浓度（例如90%O2）下也约20000小时的长寿命。
A limiting current type of oxygen sensor using a zirconia solid electrolyte has been developed and used for many applications. This sensor has some excellent features such as a long life, no reference gases, a compact body and is maintenance free. However, there were some problems to be solved for practical usage. Some improvements have been made in order to realize a high performance oxygen sensor. The main improved items are the response time, vibration resistance, waterproofness and lifetime. Details of improved items and characteristics of this sensor are reported in this paper. As a result, a high performance oxygen sensor that has a fast response time, less than 5 s, a high vibration resistance against ±30g, a waterproof property and a long lifetime of about 20 000 hours even in high oxygen concentrations such as 90% O2, was realized.
