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 pressure seals, all using field-proven silicon strain gauge sensors and common topworks.


This is a two-line digital indicator with on-board pushbuttons that displays the measurement with a choice of units. The pushbuttons allow zero and span adjustments, as well as local configuration without the need for a Communicator or PC-based Configurator.


A common HART electronics module is used for all I/A Series 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 transmitter modular design allows easy migration to other standards, including FoxComTM, FOUNDATIONTM fieldbus, and Analog 4 to 20 mA or 1 to 5 V dc.

HART Communication Protocol Version (-T Electronics)

4 to 20 mA with HART communications. Allows direct analog connection to common receivers while still providing full digital communications using a Communicator, PC-based Configurator, or optional LCD Indicator.
HART Communicators can be upgraded with software to accommodate these transmitters. Also, Invensys will make use of the HART Foundation library of registered DDs (Device Descriptors), and reload a Communicator if the user desires to keep another supplier's DD along with the Foxboro DD.
In addition to HART, Invensys also offers transmitters with other protocols as described below.

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 across the network.

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.

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. As with the -A version, it includes a standard LCD Indicator. Refer to PSS 2A-1C13 D.

HART Intelligent Module Configured for 4 to 20mA 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 pressure units, but also the electronics temperature and sensor temperature 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 the optional LCD Indicator with pushbuttons.


Both direct-connected and bracket-mounted transmitters utilize microprocessor-based correction to achieve both excellent accuracy and ambient temperature compensation.


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.


Point-to-point or multidrop topologies are permitted. Multidropping is the connection of several transmitters to a single communications line. Communications between the host computer and transmitters takes place digitally with the analog output of the transmitter fixed. Up to fifteen transmitters can be connected on a single twisted pair of wires or over leased telephone lines.


Direct Connected Transmitters (Models IAP10 and IGP10)
These transmitters are light weight and easy-to-install. They use 316L ss or nickel alloy (equivalent to Hastelloy®) process connections, and a choice of either 316L ss, Cobalt-Nickel-Chrome, or nickel alloy for the sensing diaphragm. See Direct-Connected Transmitters section.
Bracket-Mounted Transmitters (Models IAP20 and IGP20)
These transmitters offer a large selection of corrosion resistant process covers and sensing diaphragm materials. They are suitable for applications requiring low spans, vacuum service, and high overrange pressure.


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.


The combination of small size, light weight, direct mounting, standard materials,and wide measurement capability with high performance make this an exceptionally cost effective solution for process pressure measurement.


Because of their light weight and external threaded connection, these transmitters can be installed directly on process piping without mounting brackets.However, for unique requirements, an optional bracket is offered and connection can be made to the standard 1/4 NPT internal thread.


Three absolute pressure versions are offered to allow spans from 7 to 21,000 kPa (1 to 3,000 psi), and four gauge pressure versions are offered to allow spans from 7 to 42,000 kPa (1 to 6,000 psi). Refer to IGP20 Transmitter for gauge pressure vacuum service.


With process connection of 316L ss or nickel alloy (equivalent to Hastelloy®) and sensor diaphragm available in either 316L ss, nickel alloy, or highly corrosion resistant Co-Ni-Cr, this transmitter is an excellent choice for the vast majority of process pressure measurements.


The IAP10 and IGP10 flameproof versions are designed to meet Agency flameproof and zone requirements.


Three high gauge pressure versions with URLs of 52,105, and 210 MPa (7,500, 15,000, and 30,000 psi)are available in the IGP10 line.


These transmitters are also available with integral process connections for use in sanitary, and pulp and paper installations. See PSS 2A-1C13 K and PSS 2A-1C13 L, respectively.



Choice of 316L ss, Co-Ni-Cr, nickel alloy (equivalent to Hastelloy®), Monel, Gold-Plated 316L ss, andTantalum materials. High corrosion resistance of CoNi-Cr(TI037-078)means long service life in many difficult applications without the extra cost for exotic materials.Also see TI 37-75b for process applicability with Co-Ni-Cr and other process wetted parts materials.


Gauge pressure measurement spans may be as low as 0.12 kPa (0.5 inH O) to as high as 35 MPa (5000 psi) by choosing one of only six sensors, and absolute pressure measurement spans may be as low as 0.87 kPa (3.5 in H 2 O) to as high as 21 MPa (3000 psi) by choosing one of only four sensors. This provides exceptional measurement range capability with a minimum of versions.


Three high gauge pressure versions with URLs of 52,105, and 210 MPa (7,500, 15,000, and 30,000 psi)are available in the IGP10 line.


A lower range limit of -100 kPa (-14.7 psi, -1 bar or kg/cm2 ) means that vacuum measurements are easily handled with the versatile IGP20 Gauge Pressure transmitter.


Removable, gasketed process connector (Figure 2)allows 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, a 1/2 NPTpvdf (Kynar) insert, as shown in Figure 3, is installed in the HI-side 316 ss cover and is used as the process connector. In these applications, tantalum is used as the sensor diaphragm material.


Optional two-valve manifold to isolate transmitter, and vent pressure, is easily mounted directly to transmitter.


The transmitters are designed to meet Agency flameproof and zone requirements.


Output Signal and Configuration

Output is 4 to 20 mA with digital HART communications. For multidrop applications, the mAsignal is fixed at 4 mA to provide power to the device. Configurable using the HART Communicator, PCbased Configurator, or optional LCD Indicator with on-board pushbuttons.

Electronics and Sensor Temperatures

Readable from the Communicator or PC-based Configurator. Measurement is transmitter temperature, at the sensor and the electronic module, not necessarily process temperature.

Field Wiring Reversal

No transmitter damage.

Suppressed Zero and Elevated Zero

Suppressed or elevated zero ranges are acceptable as long as the Span and Range Limits are not exceeded (elevated zero applicable to IGP20 only).

Zero and Span Adjustments

Zero and span adjustments can be initiated using the Communicator, a PC-based Configurator, or the optional LCD with on-board pushbuttons.

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.

Supply Voltage Requirements and External Loop Load Limitations

Nominal minimum supply voltage 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 as shown in the Physical Specifications section.
