The Zirconia Oxygen Sensor System offers a complete solution, removing the need for customers to develop their own electronics. Frequently used in combustion control systems, burning coal, oil, gas and biomass and in oxygen generation systems. The Zirconia Oxygen Sensor System consists of SST’s fast response (<4s T90) zirconium dioxide (ZrO₂) screw fit sensor in conjunction with the OXY-LC oxygen sensor interface board. The system employs a well proven, zirconium dioxide element at its heart and, due to its innovative design, does not require a reference gas. This, along with its rugged stainless steel construction means the sensor can be used in extreme temperatures and aggressive environments. These 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 sensor is housed in a short probe with an M18x1.5mm thread, making installation quick and easy. The oxygen sensor can operate in temperatures ranging from -100°C to 250°C and has a lifetime of up to 10 years (depending on the application). When connected to the OXY-LC interface board, the zirconia oxygen sensor can measure oxygen concentrations of 0.1% to 25% and 0.1% to 100%.
