Product Specification

Flange Mount Zirconia Oxygen Sensor Description
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 4 or 5 pin termination, a temperature range of -100 to 400⁰C 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.
