The Miniature Zirconium Dioxide Oxygen Sensors can be PCB mounted and are used when measuring ambient gas with the complete sensor immersed in the atmosphere which is to be measured. SST’s range of Miniature Zirconium Dioxide 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. 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 Miniature oxygen sensor is just 12mm in diameter making it suitable for applications where space is limited. The sensor offers an option of two response times and a temperature range of -100 to 250⁰C. The oxygen sensor offers a linear output signal, a lifetime of up to 10 years (depending on the application), and covers an oxygen range from 0.1 to 100% O₂. All of SST’s zirconia oxygen sensors require interface electronics to operate which SST can provide (see related products below). For high volume applications, we can work with you to design your own electronics, saving you time and money.
