The LuminOx Fluorescent Optical Oxygen Sensor is moving the industry forward like never before. Electrochemical sensors are sensitive to temperature and therefore require external compensation, using hardware or software methods. LuminOx contains built-in temperature compensation, so removes this requirement. Not only does LuminOx measure the temperature but also its two-wire communication port allows the gas temperature to be measured along with oxygen by the host – an added bonus!
The graphs below show how LuminOx’s output remains constant while the gas temperature is changing. Electrochemical sensors, tested at the same time, exhibit significant errors as a result of the changing temperature.
The three sensors were supplied with various fixed gas concentrations and the temperature was varied between -20 and +50degC. The graph below show the results for 0% O2 and 20% O2:
