Frequently Asked Questions
What are zirconia oxygen sensors used for?
Zirconia oxygen sensors are used for continuous oxygen measurement in applications such as industrial combustion, boiler control, emissions monitoring, inerting, controlled atmospheres and additive manufacturing.
How do zirconia oxygen sensors work?
A zirconium dioxide sensing element is heated to a high operating temperature, allowing oxygen ions to move through the ceramic material. The resulting electrical signal changes with the oxygen concentration being measured.
Do zirconia oxygen sensors require a reference gas?
SST zirconia oxygen sensors use a closed-loop measurement system and do not require a separate reference gas. This simplifies installation and supports reliable long-term operation.
