SST Zirconia Oxygen Sensors
SST’s range of Zirconia Oxygen Sensors use a unique closed loop measurement system. While the sensor continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures. The sensing technology and stainless steel construction allow Zirconia Oxygen Sensors to be used in environments where extreme pressure, temperature and high humidity are present. SST’s zirconium dioxide oxygen sensors offer a range of housing styles, cabling and electrical connections. The sensors can be purchased alone or with integrated electronics offering digital or analogue industry standard outputs. Their long operating life is due to the non-depleting sensor cell technology. No reference gas is required and easy single point calibration can be performed in any known gas including fresh air. The oxygen sensors can measure over a wide oxygen range (0.1 to 100% O₂).
The reliability of these sensors means that they are used globally in applications ranging from composting to fuel tank inerting in civilian airliners.
