Siemens introduces Oxymat 64 oxygen sensor
A new gas analyzer that would measure the small concentrations of oxygen that are present in fuels has been developed by Siemens Automation and Drives (A&D). The company calls it the Oxymat v64. This is an oxygen sensor and it quantifies down to the levels of 0 to 10 parts per million. Thus this oxygen sensor is suitable to be used for technical gas production, welding applications, air separation plants, food and beverage industry, hardening shops, and chemical industry. The new 19-inch gas analyzer continues the series of Oxymat 6 which has been used foe ten years now with measuring qualities of up to 50 parts per million.
This new oxygen sensor makes use of the same display unit and operator interface like the other devices of the series. Besides those, it also employs the same mechanical components and electronic modules. The analyzer’s core is also available commercially which is the tubular ZrO2 or zirconium dioxide sensor that’s already field-proven for a lot of years. The sensor is warmed up to 650 degree Celcius and the sample gases flow through them in a steady flow rate, while the sensor’s exterior is exposed to the ambient air. The concentration difference on both sides results in a possible inconsistency that is a gauge of the concentration of oxygen in the sample gas. There is an option between a catalytical inactive ZrO2 sensor and a catalytical active ZrO2 sensor and it depends on the application. These active and inactive ZrO2 sensors are both characterized by a high level of linearity but their difference lies in the electrode materials which react differently to the accompanying combustible components.
