SO-B0-001 Limiting Current Type Zirconia Oxygen Sensor Operational Principle When voltage is applied to a zirconia electrolyte cell, oxygen is pumped through the zirconia disc from the cathode side to the anode side because the carriers of the current flowing through the zirconia electrolyte are oxygen ions. By attaching a cap with a pinhole on the cathode side of the cell and by increasing the voltage over the cell the current shows saturation due to the rate limiting step in the transfer of oxygen to the cathode. This saturation current is called limiting current and is nearly proportional to the ambient oxygen concentration. Below the advantages of the Zirconia Oxygen Sensor SO-B0-001: * Measuring range 10 ppm to 1000ppm oxygen * High accuracy * For many types a more or less linear characteristic * Small temperature dependence of the sensor signal * Low interference with other gases * Long service life * In many cases "Single point calibration" necessary only once SO-B0-001 Limiting Current Type Zirconia Oxygen Sensor Applications: * Medical * Laboratory * Food industry * Household/Gastronomy * Measuring technique * Security technology/Monitoring * (Electrical-) industry SO-B0-001 Limiting Current Type Zirconia Oxygen Sensor Characteristic Data: * TO8 Housing * Measuring gas: Oxygen concentration * Measuring medium: Gaseous atmosphere * Measuring principle: Limiting current type sensor * Measuring ranges: 10 ppm - 1000 ppm O2 * Output current: 70 A - 140 A * Accuracy: ±20 ppm O2 * Reproducibility:

LOX-02-F LuminOx Flow-through Optical Oxygen Sensor General Description The LuminOx Flow-Through Optical Oxygen Sensor Allows For A Clean Gas Sample Stream Directly Into The Sensor Which Can Be Completely Removed From The Process Environment. The LuminOx Flow-through Optical Oxygen Sensor is developed and manufactured by SST, it is part of the LuminOx family, which is a range of factory calibrated oxygen sensors which measure ambient oxygen levels using the principle of fluorescence quenching by oxygen, also known as luminescence quenching. The LuminOx Flow-through Optical Oxygen Sensor (LOX-02-F) is an extension to the standard range of LuminOx oxygen sensors. The original LOX-02 sensor was designed to be completely immersed in the sample gas environment as the base of the sensor is not gas-tight. The flow-through housing style is sealed on the base which allows for a clean gas sample stream into the sensor which can be completely removed from the process environment. A flow-through housing allows for better sample gas management and options in terms of where the sensor can be situated. The patented technology allows SST to produce a range of sensors that are based on a non-depleting operating principle. This can contribute to the LuminOx sensors having a comparably longer lifetime that other competitor technologies, such as galvanic sensors, for similar applications. LOX-02-F LuminOx Flow-through Optical Oxygen Sensor Features * Luminescence-based optical technology, NOT electrochemical * Contains no hazardous materials; RoHS & REACH compliant * Connects directly to a microcontroller without any additional circuitry * Factory calibrated * High accuracy, fast response * Maintenance free LOX-02-F LuminOx Flow-through Optical Oxygen Sensor Benefits * Compact, flow-through housing with sealed base * Low power, long life due to non-depleting sensing principle * Low cos OX-02-F LuminOx Flow-through Optical Oxygen Sensor Technical Specifications *â?¢ Supply voltage: 4.5 - 5.5V DC * Supply current:

OPTOD Optical Dissolved Oxygen & Temperature Sensor Optical technology: The OPTOD sensor is based on luminescent optical technology and is approved by the ASTM International Standard Method D888-05. Without calibration requirements, and thanks to an ultra low power technology, the OPTOD sensor is suitable for field work as well as long and short term monitoring. With no oxygen consumption, this technology gives an accurate measure in all situations, even in very low oxygen concentrations. Digital Technology: The "smart" OPTOD sensor stores calibration and history data within the sensor. This allows you a "plug and play" system without re-calibration.
