DESCRIPTION AND SPECIFICATIONS

760007-A July 2003

SECTION 1

1-1 OVERVIEW

This manual describes the Paramagnetic Detector (PMD) Analyzer Module of Rosemount Analytical's NGA2000 Series of gas analysis components.

The PMD Analyzer Module is designed to continuously determine the concentration of oxygen in a flowing gaseous mixture. The concentration is expressed in ppm or percent volume O

The entire Analyzer Module is designed as a slide-in module (if configured in stand-alone instrument fashion), removable from the front of the Platform, with gas connections made from the rear. All electronics relative to sample detection and conditioning are included in this module.

1-2 TYPICAL APPLICATIONS

PMD Analyzer Module applications include:

• process control

• continuous emissions monitoring sy st ems

(CEMS)

• industrial gas production

• fermentation process monitoring

1-3 THEORY OF TECHNOLOGY

Oxygen is strongly paramagnetic (i.e., capable of becoming a temporary magnet when placed in a magnetic field) while most other common gases are weakly diamagnetic (i.e., tend to be non-magnetic). See Figure 1-1 below.

The Magnetic susceptibility of the flowing gas sample is sensed in the detector/magnet assembly. As shown in Figure 1-2 on page 1-2, a dumbbell shaped, nitrogen-filled, hollow gas test body is suspended on a platinum/nickel alloy ribbon in a non-uniform magnetic field.

Because of a "magnetic buoyancy" effect, the spheres of the test body are subjected to displacement forces, resulting in a displacement torque proportional to the magnetic susceptibility of the gas surrounding the test body.

Measurement is accomplished by a nullbalance system, whereby the displacement torque is opposed by an equal and opposite restorative torque. The restoring current is automatically maintained at the correct level by an electro-optical feedback system. A beam of light from the source LED is reflected off the square mirror attached to the test body onto a bi-cell (dual photodiode).

The current required to keep the test body to the null position is a linear function of the total magnetic susceptibility of the sample gas.

See Figure 4-1 on page 4-1, Figure 4-2 on page 4-2, and Figure 4-3 on page 4-3 for component configuration.

INSTALLATION

WARNING

If the Paramagnetic Analyzer Module is received as a separate unit, carefully examine the shipping carton and contents for signs of damage. Immediately notify the shipping carrier if the carton or contents is damaged. Retain the carton and packing material until all components associated with the Analyzer Module are operational.

2-2 ASSEMBLY

If the Analyzer Module requires assembly with other components (e.g., the Platform and associated I/O Modules), do so at this time. Following the guides on the bottom left and bottom center of the Platform, carefully slide the Analyzer Module halfway into place.

HAND INJURY HAZARD

Do not place hands or fingers in the Platform front handles when front panel is open. Dropping the front panel of the Platform while hand or fingers are inside either handle can cause serious injury.

Lift the spring-loaded pins on the front of the Analyzer Module, and carefully slide it the rest of the distance. Secure the module in position by releasing the pins, which seat in the available holes in the bottom of the case (see Figure 2-1 below). If the module and Platform are difficult to assemble, remove the module, ensure the top cover of the module is firmly seated on the hold-down screws, and repeat the assembly procedure.

Install I/O Module(s) according to guidelines in the I/O manual. After startup and calibration have been performed, secure the front panel with the six screws provided.

2-3 LOCATION

Install the Analyzer Module in a clean, nonhazardous, weather protected, vibration free location free from extreme temperature variations. For best results, either install the module near the sample stream to minimize sample transport time or supply a flow greater than necessary and route only the appropriate amount through the Analyzer Module.

Observing these requirements are critical. Note the following:

• Excessive vibration can cause a noisy readout. To minimize vibration effects, the detector/magnet assembly is enveloped in a shock-mounted compartment.

• The user should ensure, when making any internal electrical connections, that no cables are placed in contact with the detector assembly or associated internal sample inlet and outlet tubing.

An oxygen-free gas, typically nitrogen, is required for use as the zero standard gas. Recommendations for span calibration gases, bases on various operating ranges, are tabulated in Table 3-4 on page 3-10. Air (20.93% oxygen) can be used as span gas regardless of the ranges used for sampling, although very low ranges may lose accuracy.

Sample Gas

Sample gas should be non-flammable.

Temperature

Sample temperature at the inlet should be from 50°F to 150°F (10°C to 66°C). A maximum entry temperature of 110°F (43°C) is recommended to prevent cooling of the sample and possible internal condensation. Such condensation could damage some components of the Analyzer Module. This recommendation can be ignored if a thoroughly dry sample is examined.

• Magnetic susceptibilities and partial pressures of gases vary with temperature. Permissible ambient temperature range is 32°F to 113°F (0°C to 45°C).

• The interior of the Detector Assembly is maintained at approximately 144°F (62°C) by an electronically controlled heater. Prior to entering the detector assembly, the sample is heated in a coiled tubing to match the detector's temperature.

2-4 GASES

a. Requirements

Calibration Gases

Analyzer Module calibration requires the establishment of zero and span calibration points. This requires a zero standard gas to set the zero point span gas to establish a calibration point at or near the upper range limit.

Pressure

Sample exhaust pressure limits are -5 to 10 psig (-345 to 690 hPa-gauge). Normal operation is in the positive range, between 0 and 10 psig (0 and 690 hPagauge). Negative gauge pressures are not normally recommended, but may be used in certain special applications.

To prevent over-pressurization, insert a pressure relief valve into the sample inlet line. A check valve should also be placed in the outlet line if the Analyzer Module is connected to a manifold associated with a flare or other apparatus that does not operate at atmospheric pressure.

The outlet port is commonly vented to the atmosphere. Any change in barometric pressure has a directly proportional effect on the indicated percent of oxygen, and should be neutralized through manual or computer correction of data. Note the following example:

2-2 Installation Rosemount Analytical Inc. A Division of Emerson Process Management

Model NGA2000 PMD

Instruction Manual

760007-A July 2003

Range = 0% to 5% oxygen Barometric pressure change after

calibration = 1% Analyzer Module measurement = 5%

oxygen Measurement error = 0.01 x 5% oxy-

gen Fullscale span = 5% oxygen

0.05% oxygen error = 1% of fullscale

The error is more significant for suppressed range 99% to 100%.

An optional barometric pressure compensation board is available to automatically perform this correction.

A general rule regarding calibration gas pressure is that it should be the same as the expected sample gas pressure during routine operation.

The above requirement increases the difficulty of operation at negative gauge pressure. A suction pump can be connected to the outlet port for drawing sample through the Analyzer Module. Such operation necessitates special precautions to ensure accurate readout, including the following:

The need for equilibrium between sample and gas calibration pressures.

Any leakage in the sample handling system will decrease readout accuracy.

Flow Rate

Recommended sample flow rate is 800 to 1400 ml/min., ±40 ml/min. Optimum flow rate is 1100 ml/min.

If flow is held to within tolerance and operating pressure remains constant, zero and span drift will meet specified limits.

b. Connections

(See Figure 2-3 on page 2-4) Connect inlet and outlet lines for sample gas to appropriately labeled fittings on the rear panel. Both connections are 1/4 inch ferrule-type compression fittings.

Zero and span gases use the same inlet and outlet as the sample. Figure 2-4 on page 2-5 shows a typical external sample handling manifold for gas selection. Particulates must be filtered down to two microns, gases generally require pressurization, and flow measurement metering MUST be present.

c. Leak Test

The Analyzer Module is thoroughly tested at the factory for gas leakage. The user is responsible for testing for leakage only at the inlet and outlet fittings on the rear panel. The user is also responsible for internal leak testing periodically and if any internal pneumatic components are adjusted or replaced (with a test procedure selected by the user).

SECTION 3

OPERATION

3-1 OVERVIEW

Prior to initial startup, the user should perform the leak test procedure outlined in Section 24c on page 2-3.

For the remainder of this section Analyzer Module interconnection with a Platform or some interfacing component will be assumed. Display and keypad information shall refer to that which the user can expect to see and do with regard to the front panel of the Platform.

For a complete description of the Platform front panel controls and indicators, see the Platform instruction manual, Displays & Operating Keys.

3-2 DISPLAYS

Three kinds of Display screens are available to the user:

• Run Mode

• Menu

• Help

a. Run Mode Display

The Run Mode is the normal mode of operation. In this mode, the Display (see Figure 3-1 on page 3-3) will show current gas measurement, the component of interest, the current operations of the softkeys, and a graphic bar representing the displayed concentration as ppm or as a percent of oxygen.

If more than one Analyzer Module is connected to the system, the Run Mode display will show as many as four gas measurements on screen. Alarm messages may also appear on the display (See Table 3-1 on page 3-2).

b. Menu Displays

The menu structure enables the user to access data and functions, and put information onto the network.

The Main Menu (Figure 3-2 on page 3-3) is subdivided into three levels of control based generally on which personnel is likely to use it: Basic Controls, Expert Controls and Setup, and Technical Level Configuration. See Figure 3-3 on page 33, Figure 3-4 on page 3-4, and Figure 3-5 on page 3-4. Many layers of the menu structure are described at appropriate places throughout this manual.

From the Run Mode display, press the MENU softkey to enter the Main Menu (Figure 3-2 on page 3-3).

c. Help Displays

The Help structure is intended to be an on-line "tutorial," context sensitive and topic-interconnected, so that the user can practically operate NGA2000 without need of an instruction manual (Figure 3-6 on page 3-4).

3-3 STARTUP PROCEDURE

Introduce a suitable on-scale gas (NOT actual sample) into sample inlet.

Apply power to the PMD Analyzer Module. If it is associated with a Platform, do this by plugging in the Platform to a power source. The Platform has no ON/OFF power switch. Once power is supplied to the Platform, the PMD Analyzer Module will be energized.

If the user's system contains only one Analyzer Module, all system components, the Controller Board and the network "self-install" (bind together) during initial startup. If the system contains more than one Analyzer Module, the startup sequence will interrogate the network to locate and identify all components on the network. The user will have to bind appropriate combinations of components after the startup sequence.

After the warm-up period, approximately one hour for PMD Module, all modules are completely functional.

Enter appropriate data in the Calibration Gas List (by making the following display selections: Main Menu, Expert Controls and Setup [enter security code, if necessary], Analyzer Module setup, Calibration Gas List). Also, enter appropriate values in the Calibration Parameters menu (by making the following display selections: Main Menu, Expert Controls and Setup [enter security code, if necessary], Analyzer Module Setup, Calibration Parameters), particularly data related to which ranges are to be zeroed together and how the Analyzer Module is expected to calibrate ranges (separately or otherwise).

The Analyzer Module will not allow the user to increase the upper limit of a range beyond the "maximum range" software setting. To change the "maximum range" value, select the following from the Main Menu: Technical Configuration Menu, Service Menu, Manufacturing Data, Analyzer Module Data. Select Maximum Range, and use the arrow keys to scroll the indicated value. The same applies for "minimum range" settings.

3-4 BINDING

To achieve full coordination between Analyzer Modules and associated I/O Modules, the user must bind those components together in the System Setup portion of the Technical Configuration Menu in software.

3-5 CALIBRATION

Calibration consists of establishing zero and span calibration points. Generally, zero and span calibration should be performed on the range that will be used during sample analysis.

To calibrate the PMD Analyzer Module, introduce zero gas into the SAMPLE INLET, and do the following:

1. If the Multi-Analyzer Module, split Run

Mode display is shown, press the DISPLAY softkey until the desired Analyzer's Run Mode display is acquired.

2. Press the MENUS softkey to enter the Main Menu.

3. Press the ENTER key to enter the Basic Controls menu.

4. Press the ZERO softkey to enter the Ana- lyzer Zero menu.

5. Press the ZERO softkey and wait.

6. Introduce span gas (Table 3-2 on page 3-

6) into the SAMPLE INLET.

7. Press the SPAN softkey to enter the Ana- lyzer Span menu, press SPAN again and wait.

8. Press the HOME softkey to re-enter the Main Menu.

9. Press the DISPLAY softkey for the Run Mode display.

For users of analyzers with suppressed indicating ranges, it may be desireable to calibrate the analyzer zero and span points within the suppressed range with gases in the sup-

Table 3-3. Calibration Range for Various Suppressed Range Operations

If the user is unable to calibrate the Analyzer Module (i.e., when ZERO or SPAN is initiated, nothing happens), a possible solution relates to the use of an incorrect gas for zeroing or spanning (e.g., using a high concentration gas to zero or a zero gas to span the Analyzer Module). Recalibrating with the appropriate gas(es) WILL NOT correct the problem because the ZERO OFFSET or SPAN FACTOR has been set to an extreme value in the process.

To remedy the problem, do the following:

1. Select the following from the Main Menu: Expert Controls and Setup (enter security

code if necessary), Analyzer Module Setup, and Calibration Parameters.

2. Using the down arrow, select Zero Ranges, press ENTER and, using the up/down arrows, toggle to SEPARATE. Do the same for the Span Ranges selection. Do not press ESCAPE at any time unless retention of prior settings is desired.

3. Return to the Main Menu (HOME) and make the following selections: Expert Controls and Setup (enter security code if necessary), Expert Analyzer Controls, CAL softkey, FACTORS softkey, and

5. Select Span Factor, press ENTER, adjust the value to 0.000015 with the up/down arrow keys, and press ENTER. Do not

press ESCAPE unless retention of prior settings is desired.

6. Attempt to recalibrate the Analyzer Module according to the procedure outlined at the beginning of Section 3-5 on page 3-5. If re-calibration fails, return to the Range Factors menu, readjust factors, and attempt calibration again.

3-6 BACKGROUND GAS COMPENSATION

Any gas having a composition other than 100% oxygen contains background gas, that is, non-oxygen components. Sometimes, the PMD Module response to background gas is significant, depending largely on the span and range used.

If the operator uses zero and span gases that contain the same background gas as the sampl e, calibration procedures automatically compensate. No adjustments are necessary.

If the background gas in the sample is different from that in the zero and/or span gases, the operator must take into consideration background effects to ensure correct readout. During entry of zero and span ga s values in the Calibration Gas List, the instrument is not set to indicate the true oxygen content of the zero and span standard gases. It is set to indicate a slightly different value, relative to background gas, calculated to provide correct readout during subsequent analysis of sample gas.

Oxygen Equivalent Values of Gases

For computation of background corrections, the analyzer's response to each component of the sample must be known. Table 3-4 on page 3-10 lists the percentage oxygen equivalent values for many common gases. For a more comprehensive list of oxygen equivalent values, refer to a resource text such as the Handbook of Chemistry and Physics for tables of magnetic susceptibility of substances. The percentage oxygen equivalent of a gas can be determined by the following equation, assuming both gases are supplied at the same pressure:

Model NGA2000 PMD

For example, if the analyzer's response to oxygen is +100%, the response to xenon would be -1.34%. The oxygen equivalent of a gas mixture is the sum of the contribution of the individual gas components. Example: Zero Based Range At lower range limit (i.e., 0% O From Table 3-4 on page 3-10, the percent oxygen equivalents are: CO

The percent oxygen equivalent of the mixture = 0.8(-0.623) + 0.2(-0.358) = (-0.4984) + (-0.0716) = 0. 570% O

%O2 Equivalent of Gas = X 100%

Computing Adjusted Values for Calibration Gas List

Before calibrating the Analyzer Module, values in the Calibration Gas List must be adjusted to correct for magnetic susceptibility of background gas. In the equation that follows, the quantities are defined as follows:

• BGGst = oxygen equivalent of background gas in standard gas (Table 3-4 on page 3-10).

• BGGs = oxygen equivalent of background gas in sample (Table 3-4 on page 3-10).

• OP = operating pressure. Unless special pressure corrections a re to be made, the zero standard, span

standard and sample gases must all be admitted at the same pressure.

Use the following equation to compute the adjusted settings for the Calibration Gas List:

(A)[100 + (B-C)]-100[B-C]

Adjusted percent oxygen for standard gas =

Instruction Manual

760007-A July 2003

In two limiting cases, the general equation is reduced to simpler forms.

1. If the span standard gas is 100% oxygen, the adjusted oxygen value is the same as the true value (i.e.,

100% O

2. If the zero standard is an oxygen-free zero gas, the adjusted value for setting the ZERO Control =

BGGst-BGGs. (If the oxygen-free zero gas is more diamagnetic than the background gas in the sam-

ple, this difference is negative. The negative value may be entered in the Calibration Gas List.) Alternately, the user can avoid these compensation calculations by using zero and span gases which have

been specially prepared to contain the expected amounts of background gas. Calibration of the analyzer module will then factor in background gas effects in the same proportions as normal run mode measurement.

3-7 BAROMETRIC PRESSURE COMPENSATION

Although normally calibrated for readout in percent oxygen, the PMD Analyzer Module actually responds to oxygen partial pressure. The partial pressure of the oxygen component in a gas mixture is proportional to the total pressure of the mixture. Thus readout is affected by pressure variations.

For instance, assume that an instrument is calibrated for correct readout with a standard gas containing 5% oxygen, admitted at the normal sea level atmospheric pressure of 14.7 psia (1013 hPa). If the operating pressure

now drops to one-half of the original value (i.e., to 7.35 psia/506 hPa and the calibration controls are left at the previously established settings, the display reading for the standard gas will drop to 2.5%.

It is therefore necessary to calibrate the instrument at the same pressure that will be used during subsequent operation, and to maintain this pressure during operation.

Alternatively, an optional Barometric Pressure Compensation Board, typically used for suppressed range applications, can perform signal corrections automatically.

When you have entered the desired number of points, return to the polynomial set up screen, and press Polynomial, and stor e it as the coefficients in the current range’s linearization function. The order of the polynomial is optimized based onthe number of data points provided. You need at least 7 points for a fourth order polynomial correction. You can modify the results with the piecewis e li n e ar correction also provided in thi s sectio n .

HOME

WARNING: The linearization curve must be monoto nic. If it is not, the calibration routine will fail and the analyzer will not calibrate. Test this by copying the values of the linearization coefficients into a spreadsheet program and plotting the result. The analyzer does test for monotonicity when it spans, but this test may not catch all possible errors. Monotonic means that the curve does not roll over and start going back down as the gas concentration

VAISALA BAROMETRIC PRESSURE TRANSDUCER

Addendum

748461-B

April 2003

This addendum serves as an amendment to the Model NGA 2000 PMD and NDIR instruction manuals. The following information should be considered part of the manual, if your instrument has a Vaisala Barometric Pressure Transducer installed in it, or if you are retrofitting a PMD or NDIR with a Vaisala transducer kit.

The Vaisala PTB100 series Analog Barometer is a N.I.S.T. traceable precision silicon capacitive atmospheric pressure transducer. The sensor delivers an analog voltage output that is inversely proportional to its inlet pressure. It has an operational ambient pressure range of 800 to 1060 hPa.

The original PMD and NDIR instruments were designed for use with a resistance bridge type of pressure transducer requiring an external gain amplifier with an offset trim The Vaisala transducer contains an integral gain amplifier that is scaled for a 0 to +5 Vdc output. The 661380 “Interface Board” contains the circuitry to convert the Vaisala single ended 0 to +5 V dc output into the referenced bridge 0 to +0.625 V dc output configuration that is required by the Analyzer module’s Computer Analysis Board. The Vaisala transducer kit is backward compatible with the original Rosemount pressure transducer.

Vaisala Interface Board Circuit Function:

The Vaisala Interface Circuit board adapts the single ended analog output of the Vaisala sensor into a Precision Voltage referenced, balanced bridge (at 1 atmosphere) input configuration. A “Bridge Balance” pot on the Vaisala Interface Circuit board provides the fine trim “Bridge Balancing” calibration adjustment that is required to set up each indi-

vidual transducer at a known ambient air pressure. Test points are provided on the circuit board for this adjustment.

The Vaisala transducer output range is 0 to +5 Vdc.

The Vaisala analog output voltage is inverted and fed into a balanced summing node that is referenced by a precision regulator. The summing node voltage is 0.000 Vdc at 1013 hPa (1 atmosphere ambient air pressure). The summing node voltage is then buffered, inverted, and gain reduced by a factor of 8 to produce the Pressure Compensation Output voltage at J12-1 for the Computer Analysis board.

Low noise, Low input current offset Op-Amps, and common substrate resistors are used to reduce gain tracking errors and null thermal coefficient effects.

1-1 INSTALLATION & RETROFIT

INSTRUCTIONS

1. Remove the original Rosemount transducer circuit board assembly, located on the motherboard at J12 and J13 (if present).

2. Install the transducer with the pressure inlet facing the rear of the instrument using the mounting studs provided on lefthand side of the detector housing.

3. Install the Interface board into it’s mating sockets (J12 and J13) on the motherboard.

4. Connect the 4-pin cable (P1) from the interface board (noting pin polarity) to the Vaisala Pressure Transducer.

5. Connect the instrument sample inlet tubing to the Vaisala Pressure Inlet port.

Model NGA2000 PMD, NDIR

Barometric Pressure menu reads the correct ambient air pressure.

6. Enable the Barometric Pressure Compensation and the Use Local Reading options via the Expert Controls – Analyzer Module Diagnostics – Barometric Pressure Compensation menus of the instrument. The instrument will automatically detect and report the ‘Presence’ of the Pressure Compensation Option.

1-2 ADJUSTMENT PROCEDURE

Circuit adjustment can be made using Barometric Pressure menu display, or an external Digital voltmeter.

Display Method

With no sample inlet lines connected and the instrument exhaust ported to atmosphere, adjust R1 on the 661380 Interface board until the Barometric Pressure reading on the

DMM Method

Connect the DMM (+) to TP1 on the 661380 Interface board, (-) to TP2. Set the DMM to measure mVDC. With no sample inlet lines connected and the instrument exhaust ported to atmosphere, adjust R1 on the Interface board until the DMM reads 0.000 Vdc ± 0.001 V. The instrument is now calibrated at 1 ATM.

1-3 HIGH ALTITUDE VERSION OPTION

For applications where the instrument is to be used above 5400 Feet (MSL) an alternate transducer option is available from the factory. This version consists of a Vaisala model PTB100B transducer (900-1100 hPa range). Please contact the factory if you require this option.
