User Guide1Genesis WDG-1200/1210Insitu Oxygen ProbesOverview1.1 System FeaturesThe WDG 1200/1210 Insitu probes are a type of direct insertion oxygenprobe used to measure the oxygen in the exhaust of a combustion process.The zirconium oxide cell is placed directly in the stream of the products ofcombustion. The probe is designed for applications in which the flue gastemperature does not exceed 1472 F (800 C), and where combustiblesmeasurements are not required. The outer probe material is 310 stainless steel,which is highly resistant to corrosion.With the unique design of the Insitu probe, field replacement of all componentsis easily performed. While the outer protection tube remains in the process, theinner tube structure, which houses the oxygen cell and furnace/thermocoupleassembly, can be removed easily (see Figure 6-1). Because there is no need toreturn the probe to the factory, extensive downtime and expensive repairs on theprobe are no longer necessary.Key Features and Benefits LED display: used to view oxygen, cell temperature, sensor temperature, orcell millivolts.An isolated linear current output for oxygen.Oxygen alarm.Diagnostics capabilities, including a system alarm.Modbus communications.CAUTIONThe components inside the probe can be hot enough to cause burnseven after having been shut down for a considerable period of time.Exercise proper safety precautions.Turn off power to the control unit when working on the probe.Page 1 - 1
Genesis WDG-1200/1210Insitu Oxygen ProbesUser Guide1.2 SensorWe recommend that all personnel who will regularly use this analyzer becomefamiliar with the following brief explanation of how the analyzer works and thecomponents that make up the analyzer.The Oxygen Measuring CellThe sensing element itself is a closed-end tube or disk made from ceramiczirconium oxide stabilized with an oxide of yttrium or calcium. Porous platinumcoatings on the inside and outside serve as a catalyst and as electrodes. At hightemperatures (generally above 1200 F/650 C), oxygen molecules coming incontact with the platinum electrodes near the sensor become ionized. As long asthe oxygen partial pressures on either side of the cell are equal, the movement israndom and no net flow of ions occurs. If, however, gases having different oxygenpartial pressures are on either side of the cell, a voltage is produced (See Figure1-1). The magnitude of this voltage is a function of the ratio of the two oxygenpartial pressures. If the oxygen partial pressure of one gas is known, the voltageproduced by the cell indicates the oxygen content of the other gas. A referencegas, usually air (20.9% O2), is used for one of the gases.Since the voltage of the cell is temperature dependent, the cell is maintained ata constant temperature. The oxygen content is then determined from the Nernstequation:E RT4FlnO1O2where R and F are constants, T is absolute temperature, and O1 and O2 are theoxygen partial pressures on either side of the cell.For measuring oxygen in non-combustibles gases, the zirconium oxide sensor canbe modeled using the Nernst equation and the equation given below:E A T log20.9%O2 Unk%AT 48.2 at 700 CWhere A is a constant, T is the cell temperature in kelvin ( C 273) and O2Unk% is the unknown oxygen concentration of the gas to be analyzed (calculatedby the analyzer).The cell produces zero voltage when the same amount of oxygen is on both sides,and the voltage increases as the oxygen concentration of the sample decreases.The voltage created by the difference in the sample gas and the reference air iscarried by a cable to the microprocessor control unit, where it is linearized to anoutput signal.NOTEBecause of the high operating temperature of the cell, combustible gasesthat are present may burn. When this occurs, the cell will generate highmillivolts and cause the display to indicate less oxygen than is actually inthe gas (net oxygen content).Page 1 - 2

The sensing cell ofthe analyzer is operated at a constant temperature. Heat is supplied tothe cell by an electrically powered internal heater. Inside the heater is athermocouple used in the cell temperature control circuit.Page 1 - 3
Genesis WDG-1200/1210Insitu Oxygen ProbesUser Guide1.3 Problems to AvoidThese are some errors to avoid. If they are avoided, your analyzer will operatewith a minimum of maintenance and troubleshooting. Do not use pipe dope or any other contaminant that gives off combustiblevapor which may cause erroneous measurements on any joints of thesample tubing.Calibration gases must contain oxygen. Do not use pure nitrogen or anyother anaerobic gas, or a zero gas.Do not use calibration gases if they contain a mixture of oxygen andcombustibles.Do not handle the cell or heater (white end) excessively. Do not try to cleanthe cell. When handling, grasp by touching the seal fitting.CAUTIONTurn off the power to the probe when working on the probe.All the parts inside the probe are hot and will cause severeburns if touched. Use gloves, wrenches, and care when workinginside the sensor.1.4 Technical SupportAMETEK/LAND is committed to providing you the best technical support in theindustry. If you need service or application assistance, please call AMETEK at 4401246 417691, or your local AMETEK/LAND representative.Before you call the factory for technical support, run test gases and record thefollowing values (you may be asked by the factory to provide this informationwhen receiving service): Cell millivolts Cell temperature Cold junction temperature Any fault indicatorsIf you need to return equipment, you will be asked to provide the followinginformation before obtaining a Return Material Authorization (RMA) number.

Genesis WDG-1200/1210Insitu Oxygen ProbesUser Guide3.2 Mechanical Installation LocationInstalling the Filter/Flame Arrestor (optional)Mounting the SensorCalibration SetupLocationCAUTIONObserve the following guidelines when selecting an analyzerinstallation location.The installation location should be free from excessive vibration. The ambienttemperature must be within the limits listed in the specifications chapter inthis manual. If the ambient temperature is outside the specified limits or thevibration is excessive, please contact LAND Sales or Service Department at 44(0) 1246 417691. There are special options to address ambient temperaturesoutside the listed specifications and special-mounting solutions can be providedfor excessive vibration installation locations.Handle the probe with care, do not drop the probe. The probe contains fragileceramic components which are easily damaged. The probe should be removedfrom the stack/flue when high pressure cleaning with a water hose, as this cancrack the zirconia cell.Select a suitable accessible position where the probe is located in the mainstream of the flue gas. Flue gas temperatures must be in the range of 20 C/68 Fto 800 C/1472 F.Avoid positions where obstructions or bends may impede the flow of gas orprevent insertion or subsequent removal of the probe.Sufficient clearance must be allowed for installation and removal of the probe. Aminimum clearance of the probe length plus an extra 25mm/ 1 in from the boilerflange or stand-off is suggested.If excessive dust flow is likely, fit a deflector plate with its apex facing the flow offlue gas.Page 3 - 2

What is an Oxygen Concentrator? Oxygen concentrators were introduced in the mid-1970's and have become the most convenient, reliable source of supplemental oxygen available today. Oxygen concentrators are the most cost-effective, efficient, and safest alternative to using high-pressure oxygen cylinders or liquid oxygen.
