1-2 SYSTEM OVERVIEW

a. Scope
This Instruction Bulletin is designed to sup­ply details needed to install, start up, oper­ate, and maintain the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer. The analyzer consists of an oxygen probe and Model 5081 Transmitter. The signal condi­tioning electronics of the Model 5081 Transmitter outputs a 4-20 mA signal repre­senting an O
value. An infrared remote
2
control (IRC) allows access to setup, cali­bration, and diagnostics. This same infor­mation, plus additional details, can be accessed with the HART Model 275/375 handheld communicator or Asset Manage­ment Solutions (AMS) software.
b. System Description
The Rosemount Analytical Two-Wire In Situ Oxygen Analyzer is designed to measure the net concentration of oxygen in an industrial process; i.e., the oxygen remaining after all fuels have been oxidized. The oxygen probe is permanently positioned within an exhaust duct or stack and performs its task without the use of a sampling system. The Model 5081 Transmitter is mounted remotely and condi­tions the oxygen probe outputs.
The equipment measures oxygen percent­age by reading the voltage developed across an electrochemical cell, which con­sists of a small yttria-stabilized, zirconia disc. Both sides of the disc are coated with porous metal electrodes. The millivolt output voltage of the cell is given by the following Nernst equation:
EMF = KT log10(P1/P2) + C
Where:
1. P
is the partial pressure of the oxygen
2
in the measured gas on one side of the cell.
2. P
is the partial pressure of the oxygen
1
in the reference air on the opposite side of the cell.
3. T is the absolute temperature.
4. C is the cell constant.
5. K is an arithmetic constant.
NOTE
For best results, use clean, dry, in­strument air (20.95% oxygen) as the reference air.
NOTE
The probe uses a Type B thermocou­ple to measure the cell temperature.
When the cell is at 550°C to 1600°C (1022°F to 2912°F) and there are unequal oxygen concentrations across the cell, oxy­gen ions will travel from the high oxygen partial pressure side to the low oxygen par­tial pressure side of the cell. The resulting logarithmic output voltage is approximately 50 mV per decade.
The output is proportional to the inverse loga­rithm of the oxygen concentration. Therefore, the output signal increases as the oxygen concentration of the sample gas decreases. This characteristic enables the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer to provide exceptional sensitivity and accuracy at low oxygen concentrations.
Oxygen analyzer equipment measures net oxygen concentration in the presence of all the products of combustion, including water vapor. Therefore, it may be considered an analysis on a "wet" basis. In comparison with older methods, such as the portable apparatus, which provides an analysis on a "dry" gas basis, the "wet" analysis will, in general, indicate a lower percentage of oxy­gen. The difference will be proportional to the water content of the sampled gas stream.
c. System Configuration
The equipment discussed in this manual consists of two major components: the oxy­gen probe and the Model 5081 Transmitter.
Oxygen probes are available in three length options, providing in situ penetration appro­priate to the size of the stack or duct. The options on length are 20 in. (508 mm), 26 in. (660 mm), or 34.625 in. (880 mm).

IB-106-5081, Rev. 1.0 May 2005
Model 5081FG
The Model 5081 Transmitter is a two-wire transmitter providing an isolated output, 4­20 mA, that is proportional to the measured oxygen concentration. A customer-supplied 24 VDC power source is required to simul­taneously provide power to the electronics and a 4-20 mA signal loop. The transmitter accepts millivolt signals generated by the probe and produces the outputs to be used by other remotely connected devices. The output is an isolated 4-20 mA linearized current.
d. System Features
1. The cell output voltage and sensitivity increase as the oxygen concentration decreases.
2. High process temperatures eliminate the need for external cell heating and increase cell accuracy.
3. HART communication is standard. To use the HART capability, you must have either:
(a) HART Model 275/375
Communicator
(b) Asset Management Solutions
(AMS) software for the PC
(a) Infrared Remote Control. The IRC
allows access to fault indication menus on the Model 5081 Trans­mitter LCD display. Calibration can be performed from the IRC keypad.
(b) Optional HART Interface. The
Two-Wire In Situ Oxygen Ana­lyzer’s 4-20 mA output line trans­mits an analog signal proportional to the oxygen level. The HART output is superimposed on the 4-20 mA output line. This information can be accessed through the following:
1 Rosemount Analytical Model
275/375 Handheld Communi­cator - The handheld commu­nicator requires Device Description (DD) software specific to the Two-Wire In Situ Oxygen Analyzer. The DD software will be supplied with many Model 275/375 units but can also be pro­grammed into existing units at most Fisher-Rosemount Ana­lytical service offices. See Section 4, HART/AMS, for additional HART information.
4. Easy probe replacement due to the light-weight, compact probe design.
5. Remote location of the Model 5081 Transmitter removes the electronics from high temperature or corrosive environments.
6. Power is supplied to the electronics through the 4-20 mA line for intrinsic safety (IS) purposes.
7. Infrared remote control (IRC) allows interfacing without exposing the electronics.
8. An operator can operate and diagnos­tically troubleshoot the Two-Wire In Situ Oxygen Analyzer in one of two ways:

9. Selected Distributed Control Systems -
10. A calibration check procedure is provided
2 Personal Computer (PC) -
The use of a personal com­puter requires AMS software available from Fisher­Rosemount.
The use of distributed control systems requires input/output (I/O) hardware and AMS Security codes are provided to (by infrared remote control) prevent unintended changes to analyzers adja­cent to the one being accessed.
to determine if the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer is cor­rectly measuring the net oxygen concen­tration in the industrial process.

e. Handling the Analyzer
The probe was specially packaged to pre­vent breakage due to handling. Do not re­move the padding material from the probe until immediately before installation.
It is important that printed circuit boards and integrated circuits are handled only when adequate antistatic precautions have been taken to pre­vent possible equipment damage.
The oxygen probe is designed for in­dustrial applications. Treat with care to avoid physical damage. The probe contains components made from ce­ramic, which are susceptible to shock when mishandled. THE WARRANTY DOES NOT COVER DAMAGE FROM MISHANDLING.
f. System Considerations
Prior to installing your Rosemount Analytical Two-Wire In Situ Oxygen Analyzer, make sure you have all the components neces­sary to make the system installation. Ensure all the components are properly integrated to make the system functional.
After verifying that you have all the compo­nents, select mounting locations and deter­mine how each component will be placed in terms of available line voltage, ambient temperatures, environmental considera­tions, convenience, and serviceability. Fig­ure 1-2 shows a typical system wiring. A typical system installation is illustrated in Figure 1-3.
