12 Rosemount Analytical Inc. Oxygen Analyzer Family History
First in situ zirconium oxide analyzer in (Model 218, under Westinghouse) Obsolete models you may hear about Model 218, 225, 218A, 132, 450, 240 World Class obsoleted in 08 Parts support will continue for some period of time X-STREAM- discontinued Jan. of 2010 Current models offered Model launched in winter, 2012 Oxymitter, circa 1998 5081FG , circa high temperature Rosemount Analytical offers good backwards compatibility New electronics work with old probes New probes work with old electronics See World Class to Oxymitter conversion guide powerpoint Probes and electronics work with most competitive hardware

13 Quiz- Family History/Technology Progression
When a customer calls requesting support for a 15 year old product, the best strategy is Comply with all requests for spare parts Force the factory to issue a letter stating how long the product will be supported Try to up-sell to today’s latest offering Go on vacation- perhaps he’ll forget about it Always take the trouble to sell today’s alternative product. Over harvesting parts sales only digs the hole deeper and deeper Our strong relationship with the customer will gradually degrade. Prices are too high– deliveries too long. Our every contact with the customer starts out with bad news.

14 Oxymitter: Transmitter-Styled Analyzer

19 Agenda Combustion Review- 2009- present Model 6888 Architecture
Model 6888 Features Sales scenarios and strategy Demo Kits Launch Promotions World Class/ Oxymitter Obsolescence Competitive Update Q&A

20 Recent History World Class removed from sale in FY 2008
X-STREAM removed from sale in Jan Design effort for the 6888 was begun in the spring 2010 GP version now available- all pricing is loaded- Basically, it’s the Oxymitter probe with X-STREAM architecture and electronics Future Phases add integral autocal, hazardous area versions, and FOUNDATION Fieldbus

21 6888 Architecture Overview- Analyzers Become Transmitters
The Xi can provide the LOI for two probes 4-20 mA signal to the control room 4-20 mA signal to the Xi. HART constitutes an internal communications bus Transmitter electronics in the probe head controls heater temperature, and results in a loop-powered 4-20 mA signal for O2 This constitutes a complete O2 system if the customer can use 475 HART communications or AMS for set-up, calibration, and diagnostics If the customer prefers to have a local operator interface (LOI), Xi electonics provides a great display, keypad, and advanced software features 4-20 mA signal to the control room Don’t forget Wireless! From Transmitter Probe or Xi

22 With The Wireless THUM, AMS has never been easier to Implement

23 Traditional Architecture
Direct Replacement Probe (no electronics) 7 conductor cable for raw signals and heater power 6888 Xi “Traditional Architecture Electronics (single channel, only) This is the most expensive arrangement, however

24 Model 6888 Overview Sealed Oxymitter Probe
Rebuildable- Heater strut, cell, and diffusers are interchangeable with Oxymitter

25 Model 6888 Overview- Probe Improvements
Sealed Oxymitter probe from flange forward 3 strut screws eliminated, replaced by a keeper ring (used in the haz. area versions for 10 years) Viton hoses 18” to 12’ long Standard wall (traditional abrasive shields available) Abrasion-resistant probe tubes Variable insertion option

26 Model 6888 Overview- Probe Improved Matrix selections
3 diffuser choices Snubber Ceramic Hastelloy Standard cell, or acid-resistant Standard wall probe tube, or abrasion-resistant Many mounting adaptors, plus variable insertion

27 Detail of Small Electronics Housing
Front Side terminations Transmitter improvements Easier “straight on” wiring Screw Terminations Test points added Termination plate covers board and provides ease of tech wiring access Back Side electronics

28 Detail of Small Electronics Housing
Transmitter Electronics Provides heater control Calculates O2 Provides a 4-20 mA O2 signal (loop powered) Transmitter probe constitutes a complete O2 measuring system Use a HART 475 or AMS for set-up calibration, and diagnostics Xi electronics is optional

29 Model 6888 With Integral Autocal

30 Integral Autocal- June-July 2013
Adds integral autocal for GP and Hazardous Areas

31 Large Housing- Integral Autocal Detail

32 New 6888 Xi Advanced Xi features
Optional Xi Electronics Provides Local Operator Interface (LOI) Single or dual channel when used with transmitter probes Single Channel, only with Traditional Architecture Advanced Xi features Autocal- SPS today, integral autocal in 6888 Phase II Flame Safety Relay- cuts power to heater upon boiler loss-of-flame indication. Advanced Software Features Extended process temperature capabiity- can be selected to start at 550C, or 736C Stoichiometer feature measures O2 deficiency in reducing conditions Programmable Reference Plugged diffuser diagnostic Software is new- will not be backwards compatible with the plain Xi. Only the plain Xi can run a 44V WC probe. However either Xi will run any existing Westinghouse/Rosemount 115V DR probe, plus most competitive probes 59

33 Automatic calibration Extended process temperature capability to 850C
Advanced Xi Features Automatic calibration Improved calibration recommended diagnostic Extended process temperature capability to 850C Stoichiometer Option- Oxygen deficiency indication in reducing conditions Programmable reference- enhanced performance at near-ambient conditions Plugged diffuser diagnostic (6888)

34 Advanced Xi Features Automatic calibration
Improved calibration recommended diagnostic No longer once an hour- now continuous Impedance trigger for calibration recommended diagnostic has been increased to eliminate nuisance alarms.

35 New Perspectives on addressing upset conditions
Event – Process temperatures increase to above heater setpoint Traditional O2 Probe response (cell heater cannot control) kill the measurement (4-20 mA signal goes to default 3.5mA) Xi Response- Switch to “Nernst” mode Compensate for temperature O2 reading still valid 8 O2 % 6 4 2 500 600 700 800 900 Heaters Temp DegC

36 High Temperature Operation
cell warranty is cut in half when operation is above 736C Stoichiometer cell - 2 yr. std., 1 year above 736C Standard cell - 1 yr std., 6 months above 736C All cell warranties are voided at operating temperatures above 800C Cell continuous to measure all the way to it’s death Electronics keeps track of max. temp.

37 New Perspectives on Addressing Upset Conditons
Event - Process upsets cause reducing conditions where O2 goes to zero Pulverized coal Mill/classifier problems Roping in the coal pipes delivering coal to the burner Burner Fouling Kilns - Hazardous Waste Fuels Recovery Boilers Process heaters - Large Fuel - Gas BTU variations FCCU regenerators

38 DCS Trend During a Reducing Process Event
Time 0% O2 No O2 Information 4 mA 20 mA Conventional Zirconia O2 response 10% O2 0% O2 - 1% O2 4 mA 20 mA 5.66 mA Time Level of O2 Deficiency Indicated X- Stream Stoichiometer continued measurement

39 1 year of O2 readings inside an FCCU Regenerator
Low O2 excursions are often followed by severe cycling as control is regained Low O2 excursions DCS Range set to -1% O2

40 Speed of response is slower in reducing conditions
Stoichiometer – Notes Not 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 conditions Reducing 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 Notes Most combustion processes do not frequently go into reducing conditions Stoichiometer is a tool to assist in safely recovering from this upset condition You can’t sell the need for the shoichiometer- If the problem doesn’t already exist, you cannot create the need in the customer’s mind Simply ask customers if they have ever experienced reducing conditions Operators are most likely to know (It’s not unusual that instrument techs might not know).

42 Advanced Xi Features Programmable reference- enhanced performance at near-ambient conditions Flue gas recirculation for controlling NOx

43 Flue Gas Recirculation
Top View O2 Probe Combustion Air from FD fan 18% O2 21% O2 Windbox Burner FGR damper 3 % O2 Flue Gas is sometimes mixed into the combustion air going to the burner to control NOx emissions. An O2 Analyzer mounted downstream of the mixing point may be used to control the rate of flue gas injection to the desired level. FGR Fan Stack

44 Advanced Xi Features Programmable reference- enhanced performance at near-ambient conditions Enriched oxygen combustion Melting steel Catalyst regeneration

45 Plugged Diffuser Diagnostic
Specification states speed of response upon the delivery of cal gases. The real speed of response is the recover to process O2 after cal gas is turned off. 6888 Xi measures this “return to process” time

46 Project Schedule Phase II Integral Autocal-Beta testing has begun-
looking for additional sites May, 2013 Haz. Area release June/July 2013 New flame arrestor design Class I Div. II Xi Phase III Hazardous Area Electronics IS 4-20 mA signal option from probe June/July 2013 Class I Div I - explo. box

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

48 Pricing Summary As of 4/2013, Model 6888 probe system list prices are 7% less than Oxymitter General Purpose HART Oxt4A - + 7% General purpose Fieldbus Oxt5A no change No Change to Oxt4C Haz. Area Haz. Area HART Oxt4C and Oxt4CNF (no cell Flame arrestor) Haz. Area Fieldbus Oxt4C and Oxt4CNF (no cell Flame arrestor) Both the 6888 Xi and the existing X-STREAM Xi are priced the same, but the Traditional Architecture version of both have been raised by 10%

50 Questions and Answers

51 Questions and Answers Q- 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 probe Modify the Xi electronics to a traditional architecture Xi Provide signal cable in the length required

52 Questions and Answers Q- 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/keypad Automatic calibration Flame Safety interlock for heater cut-out Advanced Software features Extended process temperature capability (heaterless operation) Stoichiometer Programmable reference Plugged diffuser diagnostic

53 Questions and Answers Q- 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.

54 Oxymitter Obsolescence
Since the probe is almost identical, the Oxymitter probe pricing has been increased app. 7% in early April. Haz. Area Oxymitter price has not changed significantly. Will still be using Oxymitter Haz. Area electronics until we get a new Haz. Area electronics
