The XMO2 thermoparamagnetic oxygen transmitter from Panametrics provides state-of-the-art oxygen measurement. It is the most stable oxygen analyser currently available on the market.
Oxygen and Gas Analysers
When choosing a gas measurement solution there are a few aspects to consider such as background gas composition within the sample gas, the temperature and the pressure on the process line, and which technology is the best fit for the application and even more. RS Hydro and Panametrics work together to deliver a total solution for all gas measurement needs, so feel free to get in contact to find out more!
About Thermal Conductivity Technology
Thermal conductivity is a fluid’s ability to dissipate heat. This property is useful in measuring binary gas mixtures such as oxygen in hydrogen, carbon dioxide in methane and other gases. Panametrics thermal conductivity sensor compares the thermal conductivity of the sample gas to that of a reference gas to determine the percent-level concentration of one gas in a two-gas or multi-gas mixture with similar thermal conductivities. Sample gas flows through the measuring cell with built-in thermistors. The thermal conductivity difference between the sample gas and reference is directly proportional to the gas concentration. Thermal Conductivity allows for percent-level measurement of one gas within another. The sensor is compact and rugged, with no moving parts. It requires minimal calibration and service and can transmit the data digitally.
About Thermoparamagnetic TechnologyOxygen has the property to be attracted into a magnetic field. This paramagnetic property can be used with heated thermistors to measure oxygen concentration. This technology contains no moving parts and is simple and easy to use. Infrequent calibrations minimise cost of ownership.
About Electrochemical TechnologyGalvanic fuel cells are used to measure trace and percent level of oxygen within gases. A reaction takes place at the cathode to form ions that travel to the anode converting lead to lead-oxide. Resulting current is proportional to the amount of oxygen present in the gas. Panametrics oxygen fuel cell technology uses a self-contained cell that requires no electrolyte refueling or electrode replacement. This provides excellent performance, stability and a long life. The sensor is insensitive to background gas changes allowing measurement of different oxygen gas concentration ranges.
About Zinconia TechnologyZinconia measures trace oxygen in clean, inert gases such as high-purity nitrogen. The sensor consists of yttrium-substituted zinonium-oxide. Platinum coating acts as an electrode. At the high operating temperatures of the sensor, oxygen reacts with the platinum to form ions that travel from the ambient air reference on the outer side of the sensor tube through the walls of the sensor to the sample gas at the inside of the sensor tube. A generated milli-volt signal correlates with the oxygen concentration within the sample gas. The lower the oxygen concentration, the greater the extent to which ions can travel through the matrix and the higher the milli-volt signal. This technology has quick response times measuring ranges from 0.1ppm to 100% oxygen. The sensor is also maintenance free and as such has a long sensor lifetime.
About Non-depletingElectrochemical Oxygen from the sample gas takes part in a reaction resulting from voltage applied from sensor electrodes. At the cathode, the oxygen is converted into hydroxyl ions which travel through the electrolyte to the anode where it is converted back to oxygen. The current is a direct measurement of the hydroxyl ion transport and therefore proportional to oxygen concentration. This is a non-depleting sensor therefore sensitivity down to the ppb-level can be provided.
