Zirconia Oxygen Sensor System
The Zirconia Oxygen Sensor System offers a complete oxygen level measurement solution removing the need for customers to develop their own electronics. It can be used in combustion control systems, coal, oil, gas, biomass and in oxygen generation systems.
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.
The 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% or 0.1% to 100% with a 4-20mA analog output. (See Sensor and Interface Selection Guide)
