SST provides a variety of zirconia oxygen sensors, including potentiometric, amperometric, and a distinctive closed-loop measurement system.
Thanks to robust stainless-steel construction and advanced sensing technology, ZrOâ‚‚ sensors are ideal for use in challenging environments with high pressure, extreme temperatures, and elevated humidity levels.
SST’s Zirconia Oxygen Sensors provide continuous oxygen measurement from 0.1% to 100% O₂ (partial pressure 2 mbar to 3 bar) using advanced closed-loop technology with a heartbeat signal for instant fault detection. Their durable stainless steel construction and zirconium dioxide sensing element ensure reliable performance in harsh environments with extreme temperature, pressure, and humidity.
Available in multiple housing options, cable types, and electrical interfaces, these sensors are adaptable for various installation needs. They can operate as standalone devices or integrate with electronics offering both digital and analog outputs. Calibration is straightforward and does not require reference gases—single-point calibration can be done using fresh air or a known gas.
With non-depleting sensor technology, they deliver a long service life of up to 10 years, reducing maintenance efforts. SST’s sensors are trusted globally for applications such as boiler combustion control, emissions monitoring, and fuel tank inerting, providing accurate real-time oxygen data to enhance industrial process efficiency.
