Oxygen Sensors, Solid State

Published on : Tuesday 30-11--0001

SST Sensing Ltd offers a comprehensive array of Oxygen Measurement Devices. Complementing the company’s high performance Zirconia product offering, the LuminOx family uses proprietary solid state technology to deliver sensors with the cost effectiveness found in commonly-used electrochemical oxygen sensors, but with a series of key additional benefits. The optically-based, factory-calibrated LuminOx sensors rely on fluorescence quenching by Oxygen. Here, pulsed light is directed onto an oxygen-sensitive fluorescent dye causing it to fluoresce. The rate at which this fluorescence decays is inversely proportional to the amount of oxygen present in the vicinity. Because the phenomenon does not deplete the fluorescent dye, LuminOx devices can be deployed for far more prolonged periods than are possible using conventional oxygen sensors in this price bracket (which are normally based on electrochemical measurement mechanisms which rely on an electrolyte which is “consumed” over time). They can remain in service of well over 5 years. Furthermore, LuminOx sensors are completely free from lead, liquid electrolytes and other hazardous materials that are present in electrochemical sensing solutions – which have significant environmental concerns associated with them.
