The Flange Mount Zirconium Dioxide Oxygen Sensor is designed for easy sealing into a manifold or sampling chamber. Favoured by SST’s aerospace customers and in applications that require high temperature and pressure operation.
SST’s range of 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 Flange Mount oxygen sensor offers complete with 0.4m of 5 single strand 20AWG cables and MOLEX 39-01-2060 connector, a temperature range of -100 to +250⁰C and response time of less than 4 seconds. The oxygen sensor offers a linear output signal, a lifetime of up to 10 years (depending on the application) and covers an oxygen range 0.1 to 100% O₂.
All of SST’s zirconia oxygen sensors require interface electronics to operate which SST can provide (see related products). For high volume applications, we can work with you to design your own electronics, saving you time and money.
