CONSIDERATIONS
Installation
This section covers areas to consider when installing the Model 1151
Analog Transmitter:
• General Considerations
• Mechanical Considerations
• Environmental Requirements
• Electrical Considerations
• Liquid Level Measurement
The accuracy of a flow, pressure, or level measurement depends on proper installation of the transmitter and impulse piping. The piping between the process and transmitter must accurately transmit process pressure to the transmitter. Mount the transmitter close to the process and use a minimum of piping to achieve best accuracy. Keep in mind, however, the need for easy access, safety of personnel, practical field calibration, and a suitable transmitter environment. In general, install the transmitter so as to minimize vibration, shock, and temperature fluctuations.
Installations in food, beverage, and pharmaceutical processes may require sanitary seals and fittings. Regulations may dictate special installation requirements needed to maintain sanitation and cleanability considerations. See Product Data Sheet 00813-0100-4016 for more information about sanitary pressure instruments from
Rosemount Inc.
Rosemount Model 1151DP, GP, HP, and AP transmitters may be mounted in several ways. They may be panel-mounted, wall-mounted, or attached to a 2-inch pipe through an optional mounting bracket.
Figure 2-1 shows the transmitter dimensions. The following paragraphs discuss factors necessary for a successful transmitter installation.

Installation
Mount the transmitter to minimize ambient temperature changes. The transmitter electronics temperature operating limits are –40 to 200 °F
(–40 to 85 °C) for “E” output options, –20 to 150 °F (–29 to 66 °C) for “J” output options, and –20 to 200 °F (–29 to 93 °C) for G, L, and M output options. Section 5 Maintenance and Troubleshooting lists the sensing element operating limits. Mount the transmitter to avoid vibration and mechanical shock, and to avoid external contact with corrosive materials.
When choosing an installation location and position, take into account the need for access to the transmitter.
Orient the process flanges to enable process connections to be made.
For safety reasons, orient the drain/vent valves so that process fluid is directed down and away from technicians when the valves are used.
This can be accomplished by pointing the hole in the outside valve body downward and away. In addition, consider the need for a testing or calibration input.
Housing Rotation
Terminal Side of
Electronics Housing
Circuit Side of
Electronics Housing
Exterior of Electronics Housing
Do not rotate the transmitter housing more than 90 degrees without disconnecting the header board. Exceeding 90 degrees rotation will damage the internal sensor module wiring. Refer to Removing the Sensor from the Electrical
Housing on page 5-6 for further information.
The electronics housing may be rotated up to 90 degrees to improve field access to the two housing compartments. To rotate the housing less than 90 degrees, loosen the housing lock nut and turn the housing not more than 90 degrees from the orientation shown in Figure 2-1. To rotate the housing more than 90 degrees, follow the transmitter disassembly procedures in Section 5 Maintenance and
Troubleshooting.
Make wiring connections through the conduit openings on the top side of the housing. The terminal side of the housing is marked on the nameplate located on the side of the transmitter. Mount the transmitter so that the terminal side is accessible. A ¾-inch clearance is required for cover removal with no meter. A 3-inch clearance is required for cover removal if a meter is installed. If practical, provide approximately 6 inches clearance so that a meter may be installed later.
The circuit compartment should not routinely need to be opened when the unit is in service; however, provide 6 inches clearance if possible to allow access for on-site maintenance. The circuit side of the housing is marked on the nameplate located on the side of the transmitter.
The analog Model 1151 uses local span and zero screws, which are located under the nameplate on the side of the transmitter. Please allow
6 inches clearance if possible to allow access for on-site maintenance.
2-3
Model 1151 Alphaline® Pressure Transmitters
Mounting Effects
The analog Model 1151 weighs 12 lb (5.4 kg) for AP, DP, GP, and HP transmitters, excluding options. This weight must be securely supported; see Figure 2-2 on page 2-6 for mounting bracket information. The transmitter is calibrated in an upright position at the factory. If this orientation is changed during mounting, the zero point will shift by an amount equivalent to the liquid head caused by the mounting position. Zero and Span Adjustment on page 3-6 describes how to correct this shift.
Process leaks can cause death or serious injury. Only use bolts supplied with the transmitter or sold by Rosemount
Inc. as a spare part. Using unauthorized bolts may reduce pressure retaining capabilities and render the instrument dangerous.
Process Connections
Do not plug the low side with a solid plug. Plugging the low side will cause an output shift.
Model 1151AP, DP, GP, and HP process connections on the transmitter flanges are ¼–18 NPT. Flange adapter unions with ½–14 NPT connections are supplied as standard. These are Class 2 threads; use plant-approved lubricant or sealant when making the process connections. The flange adapters allow users to disconnect from the process by removing the flange adapter bolts. Figure 2-1 on page 2-2 shows the distance between pressure connections. This distance may be varied ± 1 /
8
inch (3.2 mm) by rotating one or both of the flange adapters.
To ensure a tight seal on the flange adapters or three-valve manifold, first finger-tighten both bolts, then wrench-tighten the first bolt to approximately 29 ft-lbs (34 Nm). Wrench-tighten the second bolt to approximately 29 ft-lbs (34 Nm).
2-4
Mounting Brackets
Installation
Process leaks can cause death or serious injury. Install and tighten all four flange bolts before applying pressure, or process leakage may result. When properly installed, the flange bolts will protrude through the top of the module housing. Attempting to remove the flange bolts while the transmitter is in service may cause process fluid leaks.
Failure to install flange adapter O-rings can cause process leaks, which can result in death or serious injury.
There are two styles of Rosemount flange adapters, each requiring a unique O-ring, as shown below. Each flange adapter is distinguished by its unique groove.

Refer to the Spare Parts List on page 6-13 for the part numbers of the flange adapters and O-rings designed for the Model 1151 Pressure Transmitter.
NOTE
If Teflon O-rings are used, they should be replaced if the flange adapter is removed.
The low-side process flange has a ¼–18 NPT connection. A flange adapter union is supplied for ½–14 NPT process connections. The flange adapter allows the transmitter to be easily disconnected from the process by removing the flange adapter bolts. On open vessels the lowside process flange is open to atmosphere and should be mounted with the threaded hole pointed down. On closed vessels this connection is used for the dry or wet leg.
An optional mounting bracket permits mounting the transmitter to a wall, a panel, or a 2-inch horizontal or vertical pipe. Figure 2-2 illustrates some typical configurations using these mounting brackets.

Taps
The following information applies to steam, liquid, and gas installations.
Different measurement conditions call for different piping configurations. For liquid flow measurement, place taps to the side of the line to prevent sediment deposits, and mount the transmitter beside or below these taps so gases can vent into the process line. For gas flow measurement, place taps in the top or side of the line and mount the transmitter beside or above the taps so liquid will drain into the process line. For steam flow measurement, place taps to the side of the line with the transmitter mounted below them to ensure that the impulse piping stays filled with condensate. See Figure 2-3 for a diagram of these arrangements.

For transmitters with side drain/vent valves, place taps to the side of the line. For liquid service, mount the side drain/vent valve upward to allow the gases to vent. For gas service, mount the drain/vent valve down to allow any accumulated liquid to drain. To change the drain/vent valve orientation from top to bottom, rotate the process flange 180 degrees.
Steam or other elevated temperature processes can cause damage to the sensor. Do not allow the temperature inside the process flanges to exceed the transmitter limit of 220 °F
(104 °C).
In steam service, lines should be filled with water to prevent contact of the live steam with the transmitter.
2-7
Model 1151 Alphaline® Pressure Transmitters
Impulse Piping
The piping between the process and the transmitter must accurately transfer the pressure in order to obtain accurate measurements. In this pressure transfer, there are five possible sources of error: leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, and temperature-induced or other density variation between the legs.
The best location for the transmitter in relation to the process pipe depends on the process itself. Consider the following general guidelines in determining transmitter location and placement of impulse piping:
• Keep impulse piping as short as possible.
• Slope the impulse piping at least 1 inch per foot (8 centimeters per meter) upward from the transmitter toward the process connection for liquid.
• Slope the impulse piping at least 1 inch per foot (8 centimeters per meter) downward from the transmitter toward the process connection for gas.
• Avoid high points in liquid lines and low points in gas lines.
• Make sure both impulse legs are the same temperature.
• Use impulse piping large enough to avoid friction effects and prevent blockage.
• Vent all gas from liquid piping legs.
• When using a sealing fluid, fill both piping legs to the same level.
• When purging is necessary, make the purge connection close to the process taps and purge through equal lengths of the same size pipe. Avoid purging through the transmitter.
• Keep corrosive or hot process material out of direct contact with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Keep the liquid head balanced on both legs of the impulse piping.
ELECTRICAL
CONSIDERATIONS
Before making any electrical connections to the Model 1151 analog, consider the following standards and be sure to have proper power supply, conduit, and other accessories. Make sure all electrical installation is in accordance with national and local code requirements, such as the NEC (NFPA 70).
Explosions can cause death or serious injury. Do not remove the instrument cover in explosive atmospheres when the circuit is alive.
Do not connect the power signal wiring to the test terminals.
Voltage may burn out the reverse-polarity protection diode in the test connection. If the test diode is destroyed, then the transmitter can still be operated without local indication by jumping the test terminals.

Volts for “G” electronics, 12 Volts for “L” electronics, and 14
Volts for “M” electronics.) can cause damage to the transmitter. Do not apply high voltage to the test terminals.
The signal terminals and test terminals are located in a compartment of the electronics housing separate from the transmitter electronics.
The nameplate on the side of the transmitter indicates the locations of the terminal and electronics compartments. The upper pair of terminals are the signal terminals and the lower pair are the test terminals. The test terminals have the same 4–20 mA output as the signal terminals and are only for use with the optional integral meter or for testing.
To make connections, remove the cover on the side marked “Terminal” on the nameplate. All power to the transmitter is supplied over the signal wiring. Connect the lead that originates at the positive side of the power supply to the terminal marked “+” and the lead that originates at the negative side of the power supply to the terminal marked “–” as shown in Figure 2-4. No additional wiring is required.
Shielded cable should be used for best results in electrically noisy environments.

Conduit Sealing
Power Supply
NOTE
When conduit lines are used, signal wiring need not be shielded, but twisted pairs should be used for best results. Wiring should be 12-24
AWG.
The 1151 has been rated as “Factory Sealed” by Factory Mutual (FM) and Canadian Standards Association (CSA). It is therefore not necessary to install conduit seals near the transmitter enclosure.
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. Signal wiring may be grounded at any one point on the signal loop, or it may be left ungrounded. The negative terminal of the power supply is a recommended grounding point. The transmitter case must be grounded through the process or conduit connections.
The dc power supply should provide power with less than 2 percent ripple. The total resistance load is the sum of the resistance of the signal leads and the load resistance of the controller, indicator, and related pieces. Note that the resistance of intrinsic safety barriers, if used, must be included.
To power the loop, connect the leads at the set of terminal screws labeled “Signal.” Figure 2-6 illustrates power supply load limitations for the transmitter:

Unused conduit connections on the transmitter housing should be plugged and sealed to avoid moisture accumulation in the terminal side of the housing. The recommended connections of conduit are shown in
Figure 2-7.
All explosion proof, flameproof, and dust-ignition proof installations require insertion of conduit plugs in all unused openings with a minimum of 40 ft-lbs (54 N-m) of torque.
This will maintain five full threads of engagement.
Grounding
Signal Wiring
Transmitter Case
If all connections are not sealed, excess moisture accumulation can damage the transmitter. Make sure to mount the transmitter with the electrical housing positioned downward for drainage. To avoid moisture accumulation in the housing, install wiring with a drip loop, and ensure the bottom of the drip loop is mounted lower than the conduit connections or the transmitter housing.
Use the following techniques to properly ground the transmitter signal wiring and case:
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. Signal wiring may be grounded at any one point on the signal loop, or it may be left ungrounded. The negative terminal of the power supply is a recommended grounding point.
The transmitter case must be grounded in accordance with national and local electrical codes. The most effective transmitter case grounding method is a direct internal connection to earth ground with minimal impedance.

NOTE
The transient protection terminal block (See Figure 4-4 on page 4-8) does not provide transient protection unless the transmitter case is properly grounded. Use the preceding guidelines to ground the transmitter case.
Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive current if a lightning strike occurs.
The capacitance sensing module requires alternating current to generate a capacitance signal. This alternating current is developed in an oscillator circuit with a frequency of approximately 32 kHz. This signal is capacitor-coupled to transmitter-case ground through the sensing module. Because of this coupling, a voltage may be imposed across the load, depending on the choice of grounding. See Figure 2-8.
This impressed voltage, which is seen as high frequency noise, will have no effect on most instruments. Computers with short sampling times will detect a significant noise signal, which should be filtered out by using a large capacitor (1
µ
F) or by using a 32 kHz LC filter across the load. Computers are negligibly affected by this noise and do not need filtering
The Model 1151 was designed with an explosion-proof housing and circuitry suitable for intrinsically safe and non-incendive operation.
Factory Mutual explosion-proof certification is standard for the Model
1151 Transmitter. Individual transmitters are clearly marked with a tag indicating the approvals they carry. Transmitters must be installed in accordance with all applicable codes and standards to maintain these certified ratings. Refer to Hazardous Locations Certifications on page 6-2 for information on the approvals associated with the analog
Model 1151.

LIQUID LEVEL
MEASUREMENT
Open Vessels
Closed Vessels
Dry Leg Condition
Differential pressure transmitters used for liquid level applications measure hydrostatic pressure head. Liquid level and specific gravity of a liquid are factors in determining pressure head. This pressure is equal to the liquid height above the tap multiplied by the specific gravity of the liquid. Pressure head is independent of volume or vessel shape.
A pressure transmitter mounted near a tank bottom measures the pressure of the liquid above.
Make a connection to the high pressure side of the transmitter, and vent the low pressure side to the atmosphere. Pressure head equals the liquid’s specific gravity multiplied by the liquid height above the tap.
Zero range suppression is required if the transmitter lies below the zero point of the desired level range. Figure 2-9 shows a liquid level measurement example.
Pressure above a liquid affects the pressure measured at the bottom of a closed vessel. The liquid specific gravity multiplied by the liquid height plus the vessel pressure equals the pressure at the bottom of the vessel.
To measure true level, the vessel pressure must be subtracted from the vessel bottom pressure. To do this, make a pressure tap at the top of the vessel and connect this to the low side of the transmitter. Vessel pressure is then equally applied to both the high and low sides of the transmitter. The resulting differential pressure is proportional to liquid height multiplied by the liquid specific gravity.
Low-side transmitter piping will remain empty if gas above the liquid does not condense. This is a dry leg condition. Range determination calculations are the same as those described for bottom-mounted transmitters in open vessels, as shown in Figure 2-9.

Calibration
Calibration of the Rosemount Model 1151 Pressure Transmitter is simplified by its compact and explosion-proof design, external span and zero adjustments, separate compartments for electronics and wiring, and weatherproof construction. Descriptions of span, linearity, zero adjustments, and damping follow.
Explosions can cause death or serious injury. Both transmitter covers must be fully engaged to meet explosionproof requirements.
When replacing housing covers, tighten the covers enough to make contact with the O-ring seals. If the covers are not tightened enough, moisture can enter the housing and cause transmitter failure.

5. Turn span screw above or below desired output by value in Step 4.
6. Repeat Steps 1 through 5 until calibrated.
1. Apply 1 V dc-point pressure for M electronics (0.8 V dc for L electronics) and turn zero screw to output 1 V dc (0.8 V dc for L electronics).
2. Apply 5 V dc-point pressure (M electronics) or 3.2 V dc (L electronics).
3. Subtract actual output from desired output.

1. Adjust the zero. With zero input applied to the transmitter, turn the zero adjustment screw until the transmitter reads 4 mA.
2. Adjust the span. Apply 100 inH
2
O to the transmitter high side connection. Turn the span adjustment screw until the transmitter output reads approximately 20 mA.
3. Release the input pressure and readjust the zero output to read 4 mA ±0.032 mA.
4. Re-apply 100 inH
2
O to the transmitter. If the output reading is greater than 20 mA, divide the difference by 3, and subtract the result from 20 mA. Adjust the 100% output to this value.
If the output reading is less than 20 mA, divide the difference by 3 and add the result to 20 mA. Adjust the 100% output to this value.
Example: The full scale transmitter output is 20.100 mA. Dividing
0.100 by 3.0 gives the product 0.033. Subtracting the product 0.033 from 20.00 mA gives the difference 19.967 mA. Adjust the 100% output to this value.
5. Release input pressure and readjust the zero.
6. Apply 100% input and repeat Steps 3 through 5 if the full scale output is not 20 ±0.032 mA.
NOTE
Under operating conditions that subject the transmitter to temperature extremes or significant vibration, mechanical backlash may occur in the zero and span adjustment screws. To improve the stability of zero and span settings in these circumstances, back off the adjustment screws slightly after final adjustment to break contact between the potentiometer blades and the adjustment screw slot surfaces.

To make large elevation or suppression adjustments, it is necessary to move the jumper on the component side of the amplifier board. Figure

ZERO AND SPAN
ADJUSTMENT
The zero and span adjustment screws are accessible externally behind the nameplate on the terminal side of the electronics housing. See Figure 3-4. The output of the transmitter increases with clockwise rotation of the adjustment screws. The zero adjustment screw and ELEVATE ZERO/SUPPRESS ZERO jumper do not affect the span. Span adjustment, however, does affect zero.
This effect is minimized with zero-based spans. Therefore, when calibrations having elevated or suppressed zeros are made, it is easier to make a zero-based calibration and achieve the required elevation or suppression by adjusting the zero adjustment screw
(and ELEVATE ZERO/SUPPRESS ZERO jumper as required).
A degree of mechanical backlash is present in the zero and span adjustments, so there will be a dead band when the direction of adjustment is changed. Because of the backlash, the simplest procedure is to purposely overshoot a larger amount before reversing the direction of the adjustment.

ELEVATED OR
SUPPRESSED ZEROS
Calibration
Non-zero-based calibrations are termed as having “elevated” or
“suppressed” zeros. Calibrations that have a lower calibrated value below zero are termed elevated. Compound ranges are included in this category. Calibrations that have a lower calibrated value above zero are termed suppressed.
The easiest way to calibrate transmitters with elevated or suppressed zeros is to perform a zero-based calibration and then elevate or suppress the zero by adjusting the zero adjustment screw.
Model 1151DP Range 4 Suppression Example: For a desired calibration of 20 to 120 inH
2
O (4.9 to 29.8 kPa), proceed as follows:
1. Calibrate the transmitter to 0 to 100 inH
2
O (0 to 24.8 kPa) as described in the zero and span adjustment information.
2. Apply 20 inH
2
O (4.9 kPa) to the high side process connection, and adjust the zero until the transmitter output reads 4 mA.
Do not use the span adjustment.
Model 1151DP Range 4 Elevation Example: For a calibration of –120 to –20 inH
2
O (–29.8 to –4.9 kPa), proceed as follows:
1. Calibrate the transmitter to 0 to 100 inH
2
O (0 to 24.8 kPa) as described in the zero and span adjustment information.
2. Apply 120 inH
2
O (29.8 kPa) to the low side process connection, and adjust the zero until the transmitter output reads 4 mA.
Do not use the span adjustment.
NOTE
For large amounts of elevation or suppression, it may be necessary to reposition the ELEVATE/SUPPRESS ZERO jumper. To do this, remove the amplifier board, and move the jumper to the ELEVATE or
SUPPRESS position as required. See Figure 3-3 on page 3-5.
LINEARITY ADJUSTMENT
In addition to the span and zero adjustments, a linearity adjustment screw (marked LIN) is located on the solder side of the amplifier board.
See Figure 3-5. This is a factory calibration adjusted for optimum performance over the calibrated range of the instrument and normally is not readjusted in the field. The user may, however, maximize linearity over a particular range using the following procedure:
1. Apply mid-range pressure and note the error between the theoretical and actual output signal.
2. Apply full-scale pressure. Multiply the error noted in Step 1 by six and then that product by the Range Down Factor, which is calculated as shown below:
Range Down Factor
=
Maximum Allowable Span
Calibrated Span
Add this result to the full-scale output (for negative errors), or subtract the result from the full-scale output (for positive errors) by turning the linearity adjustment screw.

Example: At 4 to 1 Range Down Factor, the mid-scale point is low by
0.05 mA. Therefore, turn the linearity adjustment screw until full-scale output increases by (0.05 mA

Access to linearity and damping adjustments is gained by removing cover on circuit board side.
Location of linearity adjustment screws may vary slightly between output codes.
DAMPING ADJUSTMENT
The amplifier boards for output options E, G, and J are designed to permit damping of rapid pulsations in the pressure source through adjustment of the damping screw shown in Figure 3-5 on page 3-8. The adjustment is marked DAMP on the solder side of the amplifier board.
The settings available provide time constant values between 0.2 and
1.66 seconds. The instrument is calibrated and shipped with this control set at the counterclockwise stop (0.2 second time constant). It is recommended that the shortest possible time constant setting be selected. Since the transmitter calibration is not influenced by the time constant setting, the damping may be adjusted with the transmitter connected to the process. Turn the damping control clockwise until the desired damping is obtained.
The adjustment screw has positive stops at both ends.
Forcing it beyond the stops may cause permanent damage.

Example 1 - Refer to Table 3-1: One method is to adjust the input and allow the transmitter output to remain at 20 mA. Use the following formula:
Corrected Input
= Desired URV + [(S
3 URV) 3 (P/1000)],
Where S = Value from Table 3-1, divided by 100.
To calibrate a Range 4 transmitter 0 to 150 inH

O (0 to 37.2 kPa) and correct for 1,500 psi static line pressure, use the following correction:

= 148.04 inches
With 148.04 inches applied as input at atmospheric pressure, set the transmitter to 20 mA. When the transmitter is exposed to 1,500 psi static line pressure, output will be 20 mA at 150 inches input.
Where computers or microprocessor receivers are used, the mathematical definitions used in the preceding tables can be used to automatically and continuously make the correction.

LCD Meter Configuration
Explosions can cause death or serious injury. When adding a meter option to a Model 1151 with an Option Code R1 or
R2 terminal block, make sure to change to cemented meter covers with a glass window. Make sure a sticker is located inside the cover that indicates a “cemented cover.” This cover is required to maintain explosion-proof approval.
The Rosemount LCD meter plugs directly into the Model 1151 to provide a highly accurate digital display of the process variable. The following explains the configuration and assembly of the LCD meter and includes the applicable functional, performance, and physical specifications. This meter adds no voltage drop in the 4–20 mA current loop when connected directly across the transmitter test terminals.
The LCD meter may be configured to meet specific requirements by using the left and right calibration buttons located on the meter face as shown in Figure 4-2. The analog bar graph is also shown in Figure 4-2.
The 20-segment bar graph is factory calibrated and represents
4–20 mA directly.

DISASSEMBLY
Read the following information carefully before you disassemble a transmitter. General information concerning the process sensor body, electrical housing, and a procedure for their separation follow. Figure
5-1 shows an exploded view of the transmitter.
The following performance limitations may inhibit efficient or safe operation. Critical applications should have appropriate diagnostic and backup systems in place.
Pressure transmitters contain an internal fill fluid. It is used to transmit the process pressure through the isolating diaphragms to the pressure sensing element. In rare cases, oil leak paths in oil-filled pressure transmitters can be created. Possible causes include: physical damage to the isolator diaphragms, process fluid freezing, isolator corrosion due to an incompatible process fluid, etc.
A transmitter with an oil fill fluid leak can continue to perform normally for a period of time. Sustained oil loss will eventually cause one or more of the operating parameters to exceed published specifications while a small drift in operating point output continues. Symptoms of advanced oil loss and other unrelated problems include:
• Sustained drift rate in true zero and span or operating point output or both
• Sluggish response to increasing or decreasing pressure or both
• Limited output rate or very nonlinear output or both
• Change in output process noise
• Noticeable drift in operating point output
• Abrupt increase in drift rate of true zero or span or both
• Unstable output
• Output saturated high or low
Explosion can cause death or serious injury. Do not remove the instrument cover in explosive atmospheres when the circuit is alive.
Explosions can cause death or serious injury. Do not break the housing seal in explosive environments. Breaking the housing seal invalidates the explosion-proof housing rating.
Electrical connections are located in a compartment identified as
TERMINAL SIDE on the nameplate. The signal and test terminals are accessible by unscrewing the cover on the terminal side. The terminals to the housing must not be removed, or the housing seal between compartments will be broken. (Not applicable to R1 and R2 Options.)

Maintenance and Troubleshooting
Be aware of the following guidelines:
• The transmitter should be removed from service before disassembling the sensor body.
• Process flanges can be detached by removing the four large bolts.
Do not scratch, puncture, or depress the isolating diaphragms. Damaging the isolating diaphragms can inhibit transmitter performance.
• Isolating diaphragms may be cleaned with a soft rag, mild cleaning solution, and clear water rinse.
FIGURE 5-1. Differential Pressure (DP)

.
Maintenance and Troubleshooting
The sensor module is not field repairable and must be replaced if found to be defective. If no obvious defect is observed (such as a punctured isolating diaphragm or fill fluid loss), the sensor module can be checked as follows.
1. Carefully pull the header assembly board off of the post connectors. Rotate the board 180 degrees about the axis formed by the connecting leads. The sensor module and electronics housing can remain attached for checkout.
NOTE
Do not touch the transmitter housing when checking resistances, or a faulty reading can result.
2. Check the resistance between the sensor module housing and pins one through four. This checks the resistance between both capacitor plates and the sensing diaphragm, which is grounded to the housing. This resistance should be greater than 10 M
V.
3. Check the resistance between pin eight and the sensor module to ensure that the module is grounded. Resistance should be zero.
NOTE
The above procedure does not completely test the sensor module. If circuit board replacement does not correct the abnormal condition, and no other problems are obvious, replace the sensor module.

3. Place the greased flange O-ring around the isolator and push it into the cavity.
Process leaks can cause death or serious injury. An incorrectly installed backup ring can destroy the o-ring and cause process leaks. Install the backup ring using the following procedure.
4. For all HP transmitters and GP transmitters Ranges 9 and 0, place the backup ring, shiny side down, on top of the O-ring. This places the flat side of the backup ring against the O-ring.
5. Carefully place the flange on top of the module, beveled side down so that the beveled flange surface mates with the beveled surface of the backup ring.
6. Keeping the flange and module together, turn them over so the
“L” side is up. Repeat Steps 3 through 5. As before, the flat side of the backup ring must rest against the O-ring.
7. Insert the four flange bolts.
8. Tighten the nuts finger tight, making sure the flanges remain parallel. The transmitter may now be moved without disturbing the O-rings.
a. Tighten one bolt until the flanges seat.
b. Torque down the bolt diagonally across.
c. Torque down the first bolt.
d. Torque down the two remaining bolts.
e. Inspect the flange-to-sensor seating to be sure that the flanges are not cocked.
f. Check that all four bolts are tightened to approximately
33 ft-lb (39 Nm).
9. Recalibrate the transmitter.
NOTE
If the Model 1151 Range 3 transmitter sensor module serial number is below 2,900,000, it must be temperature cycled whenever changing or rebolting flanges.

Pressure Transmitters
Optional Plug-in Meters
The optional indicating meters available for Rosemount Model 1151 transmitters are listed in Section 4 Options. Please be aware of the following information while assembling the meter assembly. Refer to
Table 6-6 on page 6-13 for part references.
• The meter may be rotated in 90-degree increments for convenient reading.
RETURN OF MATERIAL
Explosions can cause death or serious injury. Do not disassemble the glass in the meter cover in explosive atmospheres. Disassembling the glass in the meter cover invalidates the explosion-proof meter rating.
• If the meter cover is removed for any reason, be sure the O-ring is in place between the cover and housing before reattachment. To maintain an explosion-proof condition, the glass in the meter cover must not be disassembled for any reason.
To expedite the return process, call the Rosemount North American
Response Center using our 800-654-RSMT (7768) toll-free number. This center, available 24 hours a day, will assist you with any needed information or materials.
The center will ask for product model and serial numbers, and will provide a Return Material Authorization (RMA) number. For safety reasons, the center will also ask for the name of the process material the product was last exposed to.
Exposure to hazardous substances can cause death or serious injury. If a hazardous substance is identified, a
Material Safety Data Sheet (MSDS), required by law to be available to people exposed to specific hazardous substances, must be included with the returned goods.
The North American Response Center will detail the additional information and procedures necessary to return goods exposed to hazardous substances.
