40 Speed of response is slower in reducing conditions Stoichiometer – NotesNot a PPM range CO analyzer. Provides a gross indication of the level of reducing conditions.Sensor electrode will degrade faster in reducing conditions, esp. when SO2 is in the process gases.Speed of response is slower in reducing conditionsReducing conditions don’t occur often,but it’s nice to have when it does happen!
41 Simply ask customers if they have ever experienced reducing conditions Strategic NotesMost combustion processes do not frequently go into reducing conditionsStoichiometer is a tool to assist in safely recovering from this upset conditionYou can’t sell the need for the shoichiometer- If the problem doesn’t already exist, you cannot create the need in the customer’s mindSimply ask customers if they have ever experienced reducing conditionsOperators are most likely to know (It’s not unusual that instrument techs might not know).

47 Sales Strategy Analyzers as Transmitters The Instruments Division (both combustion and liquid) are moving towards “smart sensor” designA transmitter probe is the least costly system, if the customer can use HART/AMSThe Xi provides a good LOI for two probes, plus advanced featuresTraditional architecture arrangements are the most expensive to build and sellXi required, single channel onlySignal cable is expensiveBetter discounting will be available for Transmitter-style probes– less so for traditional architecture

51 Questions and AnswersQ- Although we are trying to follow the Measurement Div. by making our analyzers like transmitters, my customers don’t want to put electronics on the O2 probe, since the flue gas ducts are often very hot.A- The transmitter electronics is rated to 85C (185F), and has been successfully tested to 100C. We have had very few temperature failures.We will convert any transmitter probe that has temperature problems to a traditional architecture system at zero cost.Convert the probe from transmitter probe to DR probeModify the Xi electronics to a traditional architecture XiProvide signal cable in the length required
52 Questions and AnswersQ- I understand that we can be much more price competitive with a transmitter probe and no Xi electronics, but do I really have full functionality if I don’t have a Xi electronics?A- Full functionality is available over HART for setting up the system, calibrating, and full diagnostics. The Xi brings the following additional functionality:Permanent local O2 indication/keypadAutomatic calibrationFlame Safety interlock for heater cut-outAdvanced Software featuresExtended process temperature capability (heaterless operation)StoichiometerProgrammable referencePlugged diffuser diagnostic
53 Questions and AnswersQ- I have a customer that already has an Oxymitter. The 4-20 mA signal is already wired into the control room. Can he add wireless capability to this same probe so he can get access the HART information via AMS?A- Yes. One can wire the 4-20 mA signal and use the THUM both.
