I/A Series PRESSURE TRANSMITTER FAMILY

The I/A Series Electronic Pressure Transmitters are a complete family of d/p Cell, gauge, absolute,
multirange, multivariable, and premium performance transmitters, as well as transmitters with remote or
direct connect seals, all using field-proven silicon strain gauge sensors and common topworks.

MODULAR ELECTRONICS

A common HART electronics module is used for all HART Pressure Transmitters. Also, because all configuration and calibration data is stored in the sensor, you can replace a HART module with another HART module without transmitter reconfiguration or recalibration.

Furthermore, if your needs change, the modular design allows easy migration to other standards - including FoxComTM, FOUNDATION fieldbus, and analog 4 to 20 mA or 1 to 5 V dc versions.

HART Communication Protocol Version -T Electronics

Version -T, 4 to 20 mA with HART communications,allows direct analog connection to common receivers while still providing full Digital Communications using a HART Communicator, PC-based configurator, or optional LCD Indicator.
In addition to HART Protocol, Invensys also offers transmitters with other protocols as described below.

FoxCom Version, Software Configurable for Digital and 4 to 20 mA Output (-D Electronics)

Provides measurement integration with an II/A Series system, or allows direct analog connection to common receivers while still providing full Intelligent
Transmitter digital communication with a PC-based configurator. Refer to PSS 2A-1C14 A.

FOUNDATION Fieldbus Version (-F Electronics)

This is a FISCO/FNICO compliant all digital, serial, two-way communication system which interconnects field devices such as transmitters, actuators, and controllers. It is a local area network (LAN) with built-in capability to distribute control application across the network. Refer to PSS 2A-1C13 E.

Analog Output Version (-A Electronics)

Provides a 4 to 20 mA analog output and includes a standard LCD Indicator to provide transmitter configuration directly from on-board pushbuttons.  refer to PSS 2A-1C14 C.

Analog Output Version (-V Electronics)

A low power, low voltage transmitter that draws no more than 3 mA, and transmits a 1 to 5 V dc output signal. Refer to PSS 2A-1C13 D.

HART INTELLIGENT MODULE CONFIGURED FOR 4 TO 20 mA OUTPUT

Measurements and diagnostics are available from the  HART Communicator connected to the two-wire loop carrying the 4 to 20 mA measurement signal by using  a bidirectional digital signal superimposed on the 4 to  20 mA current signal.
Multiple measurements are transmitted digitally, including not only the primary measurement in either pressure or flow units, but also the electronics and sensor temperatures which can be used to monitor external heat tracing equipment. Complete transmitter diagnostics are also communicated. Configuration and reranging can be accomplished with the Communicator, PC-based configurator, or Digital Indicator (with pushbuttons) option.

HIGH PERFORMANCE

Transmitters are accurate to ±0.05% of calibrated span in the digital linear mode, and ±0.060% of calibrated span in the 4 to 20 mA linear mode, as well as microprocessor-based correction to achieve excellent ambient temperature compensation.

OPTIONAL SIL2 TRANSMITTERS

Modern industrial processes tend to be technically complex and have the potential to inflict serious harm to persons or property during a mishap. The IEC 61508 standard defines safety as “freedom from unacceptable risk.” SIL2 pressure transmitters with HART communication protocol, in conjunction with Triconex Safety Systems, provide integrated solutions for safety and critical control applications. The integrated solution is certified as interference-free from the 4 to 20 mA loop; this guarantees the integrity of the safety system and the safety of the controlled process. The integrated design allows uninterrupted operation of the safety function, while allowing access to device level information via HART commands. The solution permits interface of device diagnostics with asset management systems without compromising functional safety. Select Option -S2 for a SIL2- Certified HART Transmitter. A copy of the certification is available via Auxiliary Specification (AS) Code CERT-S.

WIDE MEASUREMENT RANGE WITH A MINIMUM OF SENSORS

Five d/p range sensors provide measurement spans from 0.12 to 21000 kPa (0.018 to 300 psi). The high turndown capability of the transmitter means that nearly all d/p applications can be satisfied with only these five ranges, greatly simplifying your spare transmitter and spare parts requirements.

MULTIDROP COMMUNICATIONS

Either point-to-point (Figure 20) or multidropping (Figure 21) is permitted. Multidropping is the connection of several transmitters to a single communications line. Communications between the host computer and transmitter takes place digitally, with the analog output of the transmitter fixed. With HART communication protocol, up to fifteen transmitters can be connected on a single twisted pair of wires or over leased telephone lines.

OPTIONAL MOUNTING BRACKET SETS

In addition to the standard style mounting bracket sets optionally offered with these transmitters, a unique universal style mounting bracket has been developed to allow wide flexibility in transmitter mounting configurations consistent with installation requirements. All mounting bracket sets allow mounting to a surface, pipe, or manifold. Refer to Dimensions - Nominal section.

PROCESS CONNECTORS

Removable, gasketed process connectors allow a wide range of selections, including 1/4 NPT, 1/2 NPT, Rc 1/4, Rc 1/2, and weld neck connections. For highly corrosive chemical processes when a traditional structure is used (see transmitter structures further in document), two 1/2 NPT pvdf inserts (Figure 1) are installed in both 316 ss covers and are used as the process connectors. In these applications, tantalum is used as the sensor diaphragm material.

SENSOR CORROSION PROTECTION

For traditional structure, choice of 316L ss, Co-Ni-Cr,  nickel alloy (equivalent to Hastelloy® C), Monel, Gold-Plated 316L ss, and Tantalum materials. High corrosion resistance of Co-Ni-Cr (TI 037-078) means long service life in many difficult applications without  the extra cost for exotic materials. See TI 037-75b for process applicability with Co-Ni-Cr and other process  wetted materials.
For low profile structures LP1 and LP2, 316L ss and nickel alloy (equivalent to Hastelloy® C) are offered as sensor materials. Refer to Transmitter Structures section that follows for description and application of traditional and low profile (LP1 and LP2) structures.

OPTIONAL LCD DIGITAL INDICATOR

A two-line digital indicator (Figure 22) with on-board pushbuttons is available to display the measurement with a choice of units. The pushbuttons allow zero and span adjustments, as well as local configuration without the need for a HART Communicator or PC- based configurator.

EASE OF INSTALLATION

Rotatable Topworks allows transmitter installation in tight places, allows indicator to be positioned in preferred direction, and eases field retrofit. Two Conduit Entrances offer a choice of entry positions for ease of installation and self-draining of condensation regardless of mounting position and topworks rotation. Wiring Guides and Terminations provide ease of wire entry and support, plenty of space to work and store excess wire, and large, rugged screw terminals for easy wire termination.

UNIQUE PROCESS COVER AND CELL BODY DESIGN

Biplanar Construction (Figure 2) maintains the traditional horizontal process connections and vertical mounting by providing a cell body contained between two process covers, while still achieving light weight, small size, and high standard static pressure rating of 25 MPa (3625 psi). This provides easy retrofit of any conventional differential pressure transmitter, and also is easily mounted in the horizontal position with vertical process connections, when required.
Process Covers (Figure 2) are fully supported by the cell body over their entire height. This prevents bending and results in a highly reliable seal. Also, this provides dimensional stability to the process covers,  nsuring that they will always mate properly with 3- valve bypass manifolds.
Process Cover Bolts (Figure 2) are enclosed to minimize corrosion and to minimize early elongation with rapid temperature increases. The design makes it less likely for the transmitter to release process liquid during a fire.
Process Cover Gaskets are ptfe as standard; ptfe provides nearly universal corrosion resistance, and eliminates the need to select and stock various elastomers to assure process compatibility.
Light Weight provides ease of handling, installation, and direct mounting without requiring costly pipe stands.

TRANSMITTER STRUCTURES

Traditional and low profile structures (LP1 and LP2) are offered to accommodate and to provide flexibility in transmitter installations. See paragraphs that follow.

Traditional Structure

The traditional structure (Figure 3) utilizes the right angle design common to most DP transmitters in use throughout the world. Process connections are oriented 90 degrees from the transmitter centerline. This traditional structure makes it easy to retrofit any transmitters of similar design. Sensor cavity venting and draining is provided for both vertical and horizontal transmitter installation, using innovative tangential connections to the sensor cavity (Figures 4 and 5). Optional side vents are offered for sensor cavity venting in the upright position (Figure 6). An extensive variety of process wetted materials are available for the process covers on this highly versatile and widely used transmitter.

Low Profile Structures

The low profile structures utilize an in-line design, placing the process connections in line with the transmitter centerline (Figures 7 and 8). This allows mounting of the transmitter in the upright position with the process connections facing downward, for connection to vertical process piping or for mounting directly to a three- or five-valve manifold. The low profile structures provide a mounting style similar to that used by competitive CoplanarTM transmitters. This makes it easy to select Foxboro transmitters for both retrofit and new applications where this type of installation is desired. Transmitters with the low profile structure can be  attached directly to existing, installed Coplanar  manifolds, such as the Rosemount Model 305RC or  Anderson Greenwood Models MB3, MB5G, and  MB5P, by use of an optional adapter plate (Figure 9).  Also, when assembled to the same process piping or  manifold as a Coplanar transmitter, one of the  electrical conduit connections is located within ± one   inch of the similar conduit connection on the   competitive transmitter, assuring ease of retrofit or   conformance with installation design drawings.
All parts making up the low profile versions are Low Profile Structure LP1 is a compact, inexpensive, identical to the parts in the traditional version except lightweight design for direct mounting to a separately for the process covers and the external shape of the mounted manifold or process piping. These sensor cell body. transmitters are not typically bracket-mounted. For user convenience, two types of low profile  structures are offered, type LP1 and LP2. The  process covers are the only transmitter parts that  differ between structure types LP1 and LP2.
Refer to the sections that follow for further descriptions of low profile structures LP1 and LP2.

Low Profile Structure LP1 – Direct Mount

Low Profile Structure LP1 is a compact, inexpensive, lightweight design for direct mounting to a separately mounted manifold or process piping. These transmitters are not typically bracket-mounted. They are supplied as standard with a single vent/drain screw in the side of each process cover. In conjunction with the standard tangential venting and draining design, they are suitable for mounting either vertically (Figure 10) or horizontally, and are suitable for nearly all applications, including liquids, gases, and steam. For horizontal installation, they can simply be “turned over” (rotated 180 degrees - Figures 11 and    12) to orient the high and low pressure sides in the   preferred locations. There is no need to unbolt  process covers. The topworks housing can also be rotated, as shown, to orient the conduit connections in the desired position. In the vertical, upright position, they are also self- draining and are ideal for gas flow rate service, when directly mounted to a manifold located above the horizontal pipeline. The vent screw can be omitted for this or other applications, if desired.

Low Profile Structure LP2 – Bracket or Direct Mount

Low Profile Structure LP2 is a universal design for either bracket or direct mounting. Drilled and tapped mounting holes facilitate mounting to either new or existing Foxboro brackets (Options -M1, -M2, and -M3), as well as standard brackets supplied with existing Coplanar transmitters. See Figure 13 and Figure 14. These transmitters can also be directly mounted to manifolds or process piping and are available with the same optional adapter used with low profile structure LP1 to fit existing Coplanar manifolds (Figure 15). For extra convenience, they use a full-featured vent and drain design, with separate vent and drain screws positioned in each cover for complete venting or draining directly from the sensor cavity. They are normally recommended for upright, vertical installation.

PRESSURE SEALS

Pressure seals are used with transmitters having a traditional structure (see “TRANSMITTER STRUCTURES” on page 5) when it is necessary to keep the transmitter isolated from the process. A sealed system is used for a process fluid that may be corrosive, viscous, subject to temperature extremes, toxic, sanitary, or tend to collect and solidify. Table 1 lists the various pressure seals that can be used with an IDP10 Transmitter. To order a transmitter with seals, both a Transmitter Model Number and Seal Model Number are required. For a complete listing of pressure seal models and specifications, see PSS 2A-1Z11 A. Also see Figure 16 for typical pressure seal configurations.

Output Signal and Configuration

4 to 20 mA with HART Communications. When  configured for multidrop applications, the mA signal is  fixed at 4 mA to provide power to the device.  Configurable using a HART Communicator, PC-based  Configurator, or optional LCD Indicator with on-board  pushbuttons.

Field Wiring Reversal

No transmitter damage.

Suppressed Zero and Elevated Zero

Suppressed/elevated zero ranges are acceptable as long as the Span/Range Limits are not exceeded.

Electronics and Sensor Temperatures

Readable from the HART Communicator, PC-based Configurator, or optional LCD Indicator with on-board pushbuttons. Measurement is transmitter temperature, not necessarily process temperature.

Adjustable Damping

Response time is normally 0.75 s, or electronically adjustable setting of 0.00 (none), 0.25, 0.50, 1, 2, 4, 8, 16, or 32 seconds, whichever is greater, for a 90% recovery from an 80% input step as defined in ANSI/ISA S51.1. (For 63.2% recovery, 0.50 s with sensors B to E, and 0.60 s with Sensor A.)

Zero and Span Adjustments

Zero and span adjustments can be initiated from the HART Communicator, PC-based Configurator, or optional LCD Indicator having on-board pushbuttons.

Zeroing for Nonzero-Based Ranges

Dual Function Zeroing allows zeroing with the transmitter open to atmosphere, even when there is a nonzero-based range. This greatly simplifies position effect zeroing on many pressure and level applications. It applies to optional LCD Indicator with on-board pushbuttons and optional External Zero Adjustment.

Current Outputs for Overrange, Fail, and Offline Conditions

OFFLINE	User configurable between 4 and 20 mA
SENSOR FAILURE	User configurable to Fail LO or Fail HI
FAIL LO	3.60 mA
UNDERRANGE	3.80 mA
OVERRANGE	20.50 mA
FAIL HI	21.00 mA

Write Protect Jumper

Can be positioned to lock out all configurators from making transmitter database changes. This makes transmitter suitable for Safety Shutdown System Applications that require this feature.
(2) Refer to Model Code section for application and restrictions related to the items listed in the table.

Square Root Low Flow Cutoff

User configurable using HART Communicator, PC- based Configurator, or optional LCD with on-board pushbuttons to provide:
User settable for cutoff to zero at any flow rate between 0 and 20% of maximum flow.
Cutoff to zero at flows <10% of maximum flow (1% of maximum differential pressure).
Or active point-to-point line between zero and 20% of maximum flow (4% of maximum differential pressure).

Minimum Allowable Absolute Pressure vs.Transmitter Temperature

With Silicone Fill Fluid Full vacuum: up to 121°C (250°F)
With Inert Fill Fluid Refer to Figure 18.

Supply Voltage Requirements and External Loop Load Limitations

Minimum voltage shown in Figure 19 is 11.5 V dc. This value can be reduced to 11 V dc by using a plug-  in jumper across the test receptacles in the field wiring compartment terminal block. See Figure 23.

Configuration and Calibration Data

All factory characterization data and user configuration and calibration data are stored in the sensor, as shown in the transmitter block diagram, Figure 17. This means that the electronics module may be replaced, with one of like type, without the need for reconfiguration or recalibration. Replacing the module can affect accuracy by a maximum of 0.20% of span. Error can be removed by a mA trim that does not require application of pressure.

Electronics Upgradeability

As stated above, all factory characterization data is stored in the sensor and is accessed by each electronics module type. This means that electronics modules can be changed from one type to another, allowing for easy upgrade from an analog output type to a fully intelligent type module. Changing module types may require reconfiguration and recalibration, but all factory characterization data is retained.

Communications

Configurable for either Analog (4 to 20 mA) or Multidrop Mode. Digital communications is provided in both modes based upon the FSK (Frequency Shift Keying) technique which alternately superimposes one of two different frequencies on the uninterrupted current carried by the two signal/power wires.

Analog Mode (4 to 20 mA)

The output signal is updated 30 times per second. Digital communications between the transmitter and HART Communicator or PC- based Configurator is rated for distances up to 3050 m (10,000 ft). The communications rate is 1200 baud and requires a minimum loop load of 250 ohms. See Figure 20.

Multidrop Mode (Fixed Current)

Multidrop Mode supports communications with up to 15 transmitters on a single pair of signal/power wires. The digital output signal is updated 4 times per second and carries pressure measurement and sensor/electronics temperatures (internal recalculation rate for temperature is once per second). Communications between the transmitter and the system, or between the transmitter and HART Communicator or PC-based Configurator, is rated for distances up to 1525 m (5000 ft). The digital communications rate is 1200 baud and requires a minimum loop load of 250 ohms. See Figure 21.

Remote Communications

The HART Communicator or PC-based Configurator has full access to all of the “Display” and “Display and Reconfigure” items listed below. It may be connected to the communications wiring loop and does not disturb the mA current signal. Plug-in connection points are provided on the transmitter terminal block.

(a) Accuracy includes Linearity, Hysteresis, and Repeatability.

Stability

Long term drift is less than ±0.05% of URL per year  over a 5-year period.(3)

Calibration Frequency

The calibration frequency is five years. The five years  is derived using the values of allowable error (% span),  TPE (% span), performance margin (% span), and  stability (% span/month); where:  Calibration Frequency = Performance Margin /Stability = Months
(3) Add an additional 0.05% to stability specification for Span Code A.

Power-up Time

,

Less than 5 seconds for output to reach first valid measurement.

RFI Effect
The output error is less than 0.1% of span for radio frequencies from 27 to 1000 MHz and field intensity of 30 V/m when the transmitter is properly installed with shielded conduit and grounding, and housing covers are in place. (Per IEC Std. 61000-4-3.)

Supply Voltage Effect

Output changes less than 0.005% of span for each 1 V change within the specified supply voltage requirements. See Figure 19.

Vibration Effect

Total effect is ±0.2% of URL per “g” for vibrations in the frequency range of 5 to 500 Hz; with double  amplitudes of 6.3 mm (0.25 in) in the range of 5 to 15 Hz, or accelerations of 3 “g” in the range of 15 to 500 Hz, whichever is smaller, for transmitter with aluminum housing; and with double amplitudes of 6.3 mm (0.25 in) in the range of 5 to 9 Hz, or   accelerations of 1 “g” in the range of 9 to 500 Hz,    whichever is smaller, for transmitter with 316 ss housing.

Position Effect

Any zero effect caused by mounting position can be eliminated by rezeroing. There is no span effect.

Static Pressure Effect

The zero and span shift for a 7 MPa, 1000 psi, change  in static pressure is:
Span Shift
±0.15% of Reading.

Switching and Indirect Lightning Transients

The transmitter can withstand a transient surge up to 2000 V common mode or 1000 V normal mode without permanent damage. The output shift is less than 1.0%. (Per ANSI/IEEE C62.41-1980 and IEC Std. 61000-4-5.)

Ambient Temperature Effect

Total effect for a 28°C (50°F) change within Normal Operating Condition limits is:
NOTE
For additional ambient temperature effect with pressure seals are used, see PSS 2A-1Z11 A.
