The first maintenance-free optical oxygen sensor for power plants.
High accuracy Luminescent Dissolved Oxygen (LDO) Sensor optimised for power industry application.
The absence of membrane and electrolyte means that the sensor accuracy is unaffected by process changes such as changes in flow. Maintenance and operating costs are significantly reduced. The sensor has been designed to ensure mechanical robustness to extend operational lifetime and optimise its total cost of ownership.
The quick response time comes from the Orbisphere K1100 two second measurement frequency. Capable of measuring accurately at this frequency over a 12 month period. With no calibration required, the K1100 surpasses other optical and electrochemical sensors that display significant drift after only a few months in the same conditions. This optical sensor is designed for minimal drift, resulting in it being the most stable sensor with the longest calibration intervals achievable in the market. This is possible by its long-life spot and optimised controller software.
Maintenance intervention is limited to 2 minutes and a zero point calibration, offering significant cost benefits compared with traditional electrochemical sensors and other luminescent sensors. Using gas phase calibration means chemicals are not required, and therefore the task is easier and safer without reducing measurement precision.
