OxyTechw² GAL Dissolved Oxygen Sensor

Galvanic Dissolved Oxygen Sensor

The OxyTechw² GAL Sensor has been designed to provide highly reliable Dissolved Oxygen measurements. The sensor employs the traditional galvanic principle.

The rugged 100 micron, HDPE membrane has been selected to provide exceptional resistance to damage. This, combined with Oxyguard’s unique electrolyte and anode material provides long term stability of 3 years and longer without the need for sensor refurbishment or membrane replacement.

The OxyTechw² GAL provides the reliable, accurate measurement that is required to operate activated sludge plants at the optimum Dissolved Oxygen concentration, maintaining the balance between the running costs of blowers and aerators and the need to produce high quality effluent.

For installation in activated sludge plants (ASP’s) we recommend that the sensor is installed using our specially designed self cleaning mounting system, with a flexible joint in the mounting shaft, this moves the sensor in the process, keeping the membrane clean by reducing bio-fouling without the use of a compressor and with the added benefit of allowing rags to fall away from the assembly. This motion is similar to that achieved by using a floating ball assembly, with the added advantage of placing the sensor below the surface of the liquor. This means that the sensor is below the level of the floating fats and greases that accumulate at the surface and results in the Dissolved Oxygen reading being more representative of the entire tank.
