Intelligent Gauge Pressure Transmitter IGP10S

IGP10

Product overview:

The I/A Series System Gauge Pressure Transmitters IGP10S are smart transmitters that provide precise, reliable, measurement of absolute and gauge pressure and feature high performance and excellent stability. The new Foxboro IAP10S and IGP10S pressure transmitters reduce inventory costs with a wide range of applications that traditionally require multiple separate transmitters; increase accuracy with the Foxboro patented multiple calibration technology and enables customers to accurately track time in service, which allows for predictive maintenance.

Key capabilities:

Industry Leading 400:1 Turndown - Excellent performance is maintained over an industry leading wide turndown range, meaning that an IAP10S/IGP10S transmitter performs better than multiple separate transmitters designed to cover the same turndown range and reduce inventory.

Patented Multiple Calibration Technology

The IGP10S pressure transmitters offer a unique patented multiple calibration technology feature that eliminates the need for a traditional single span calibration at application-specific pressure ranges. The multiple calibration technology feature enables multiple (11) calibrated ranges to be stored in the onboard memory and are preset in the factory and cover the full pressure range of the transmitter. During operation, a real-time seamless transition from one calibrated range to another maintains accuracy as a percent of reading from 3% to 100% of the upper range limit (URL).

Time in Service Features for Advanced Diagnostics

The Time in Service meter tracks both the total number of days the transmitter has been powered up in the field over its lifetime (total days), and also tracks the number of days the transmitter has been powered up since the last Time in Service meter reset (user days), which allows clients to better track reliability. The user day’s value can be reset to zero using a HART communicator, a PC-based configurator, or the optional local indicator. However, the lifetime service parameter cannot be reset.

HART COMMUNICATION PROTOCOL VERSION -T ELECTRONICS

4 to 20 mA with HART 6 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. 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 onthe 4 to 20 mA current signal. Multiple measurements are transmitted digitally,including not only the pressure measurement, 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 a HART communicator, PC-based configurator,or the optional LCD indicator with pushbuttons.

TIME IN SERVICE METER

Similar to how an odometer allows an automobile owner to track the total number of miles driven and a trip odometer tracks the number of miles driven since a user-defined starting point, the IAP10S/IGP10S transmitters allow you to keep track of the number of days the transmitter has been in service. The Time In Service meter tracks both the total number of days the transmitter has been powered up in the field over its lifetime (total days),and also tracks the number of days the transmitter has been powered up since the last Time in Service meter reset (user days). You can reset the user days value to zero using a HART communicator, a PC-based configurator, or the optional local indicator,but you cannot reset the lifetime service parameter.

WIDE RANGEABILITY

Three absolute pressure versions are offered to allow spans from 0.5 to 2000psi (0.0034 to 13.8 MPa), and four gauge pressure versions are offered to allow spans from 0.3 to 6000 psi (0.002 to 41.4MPa).

WIDE TURNDOWN RANGES

Excellent performance is maintained over a wide turndown range, meaning that an IAP10S/IGP10S transmitter performs as well as, or better than, two separate transmitters designed to cover the same turndown range. The turndown ratio for span adjustment is up to 400:1. This means that the IGP10S transmitter with its 200 psi URL sensor can be set to provide a 4 to 20 mA output for any range between 0 to 0.5 and 0 to 200 psi (0 to 0.0034 and 0 to 1.38 MPa). Similarly,the IGP10S transmitter with its 2000 psi URL sensor covers any range between 0 to 5 and 0 to 2000 psi (0 to 0.034 and 0 to 13.8 MPa). Accuracy of ±0.060% of span is maintained for a span adjustment turndown range of up to 80:1.

FOXBORO PATENTED MULTIPLE CALIBRATION TECHNOLOGY

The Foxboro S Series gauge and absolute pressure transmitters offer a unique patented multiple calibration feature that eliminates the need for a traditional single span calibration at an application-specific pressure range. Transmitters with the multiple calibration feature enabled use multiple calibrated ranges that are stored in on-board memory. The calibrated ranges are preset in the factory and cover the full pressure range of the transmitter. During operation, a real-time, seamless transition from one calibrated range to another maintains digital accuracy as a percent of reading from 3% to 100% of the upper range limit (URL). Factory calibration and field calibration for specific applications are not required for zero-based ranges up to 30:1 turndown. You can simply configure or rerange the upper range value (URV) without performing a recalibration at the URV. You will only need to perform a zero adjustment after installation to obtain performance to the specified reference accuracy.

OPTIONAL CALIBRATION CERTIFICATE

Optionally, you can request a calibration certificate with your IAP10S or IGP10S transmitter, which provides verification that the transmitter meets the reference accuracy specification within a user specified range. For transmitters shipped with the multiple calibration feature enabled and the Calibration Certificate option selected, the transmitters are not recalibrated to the user specified range. The LRV and URV points are configured (Reranged) to the user specified values and the accuracy is verified over that specific range.

CUSTOM FACTORY CALIBRATION

A custom two-point factory calibration is also available as a model code option. This option is useful if your application requires non-zero based ranges with greater than 10:1 turndown, zero-based ranges with greater than 30:1 turndown, or when mandated by a specific requirement. When a transmitter is shipped with the custom factory calibration option, the multiple calibration feature is automatically disabled and a traditional two-point calibration is performed.

HIGH PERFORMANCE

A custom two-point factory calibration is also available as a model code option. This option is useful if your application requires non-zero based ranges with greater than 10:1 turndown, zero-based ranges with greater than 30:1 turndown, or when mandated by a specific requirement. When a transmitter is shipped with the custom factory calibration option, the multiple calibration feature is automatically disabled and a traditional two-point calibration is performed.

HIGH PERFORMANCE

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

MULTIDROP COMMUNICATIONS

Point-to-point or multidrop topologies are permitted.Multidrop communication is the connection of several transmitters to a single communications line. Communication 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.

WIDE VARIETY OF MATERIALS

With process connection of 316L ss or nickel alloy (2)and sensor diaphragm available in either 316L ss,nickel alloy, or highly corrosion resistant Cobalt-Nickel-Chrome (Co-Ni-Cr), this transmitter is an excellent choice for the vast majority of process pressure measurements.

EASE OF INSTALLATION

These transmitters are light weight and easy-to-install.Rotatable Topworks allows transmitter installation intight places, allows indicator to be positioned inpreferred 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 ands tore excess wire, and large, rugged screw terminals for easy wire termination.

OPTIONAL LCD DIGITAL INDICATOR

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 HART communicator or PC-based configurator.

EXCEPTIONAL VALUE

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.

DIRECT PROCESS MOUNTING

Because of their light weight and external threaded connection, these transmitters can be installed directly on process piping without mounting brackets. Optional mounting brackets are also offered for unique mounting requirements.

FLAMEPROOF DESIGN

The IAP10S and IGP10S flameproof versions are designed to meet Agency flameproof and zone requirements.

PRESSURE SEALS

Pressure seals are used with the IAP10S, IGP10S,Series Transmitters 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 seals that can be used with these transmitters. To order a transmitter with seals,both a Transmitter Model Number and Seal Model Number are required. See PSS 2A-1Z11 A for a complete listing of pressure seal models and specifications.

FUNCTIONAL SPECIFICATIONS

Output Signal and Configuration

Output is 4 to 20 mA with digital HART communications. For multidrop applications, the mA signal is fixed at 4 mA to provide power to the device. Configurable using the HART communicator,PC-based configurator, or optional LCD indicator with on-board pushbuttons.

Electronics and Sensor Temperatures

Electronics and sensor temperatures are readable from the HART communicator or PC-based configurator. This measurement corresponds to the transmitter temperature at the sensor and electronic module; it is not necessarily the process temperature.

Field Wiring Reversal

Accidental reversal of field wiring will not damage the transmitter, provided the current is limited to 1 A or less by active current limiting or loop resistance.Sustained currents of 1 A will not damage the electronics module or sensor, but could damage theterminal block assembly and external instruments in the loop.

Suppressed Zero

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

Zero and Span Adjustments

Zero and span adjustments can be initiated using aHART communicator, a PC-based configurator, or the optional LCD indicator with on-board pushbuttons.

Write Protect Jumper

The transmitter has a write protect jumper that can be positioned to lock out all configurators from making transmitter database changes. This makes the 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.

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 the LCD Indicator pushbuttons and optional External Zero Adjustment.

Adjustable Damping

Damping is user-selectable to values of 0, 0.25, 0.5,1, 2, 4, 8, 16, or 32 seconds. NOTE Selecting “DAMP 0” in the damping menu will give the fastest response. For optimal performance, “DAMP 0” is not recommended with turndown ranges exceeding 30:1.

Transmitter Response Time

With damping set to 0 s, the transmitter response time is less than 100 ms for a 63% response to a pressure step change.

Minimum Allowable Absolute Pressure vs.Transmitter Temperature

With Silicone Fill Fluid, Full Vacuum: up to 121°C (250°F) With Inert Fill Fluid

Configuration and Calibration Data and Electronics Upgradeability

All factory characterization data and user configuration and calibration data are stored in the sensor (refer to Figure 5, Transmitter Functional (Diagram). This means that the electronics module may be replaced, with one of like type, with a minimal amount of reconfiguration Module replacement can affect the accuracy by 0.10% of span.

Communications

Transmitter communication is configurable for either analog or multidrop (fixed current) mode. Digital communication 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 4 to 20 mA output signal is updated multiple times per second. Digital communications between the transmitter and HART communicator 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.

Multidrop Mode (Fixed Current)

This mode supports communications with up to 15 transmitters on a single pair of signal/power wires. The output signal is updated 4 times per second and carries not only the pressure measurement, but also the sensor and electronics temperatures. Communication between the transmitter and system, or between the transmitter and communicator or configurator, is rated for distances up to 1525 m (5000 ft). The communications rate is 1200 baud and requires a minimum loop load of 250 ohms.

Remote Communications

The HART communicator or PC-based configurator has full access to 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 for the communicator are also provided on the transmitter terminal block.
The following information can be continuously displayed:

  • Process Measurement in two formats
  • Electronics and Sensor Temperatures
  • mA Output
  • Total number of days the transmitter has been powered up (not configurable)
  • Number of days the transmitter has been powered up since the last Time in Service meter reset.

The following information can be continuously displayed and configured:

  • Two Digital Outputs for Pressure
  • Choice of Pressure Engineering Units
  • Reranging without Pressure
  • Zero and Span CalibElectronic Damping
  • Temperature Sensor Failure Strategy
  • User Damping (Process Noise Damping)

Custom Factory Calibration (Option -C1)

If you want to override the default multiple calibration behavior, specify Option -C1 to replace multiple calibration with a custom 2-point calibration. Be sure to indicate the calibration range required in the sales order.

Optional Full Factory Configuration (Option -C2)

For the transmitter to be custom configured by the factory, the user must fill out a data form. If this option is not selected, a standard (default) configuration will be provided.

Optional LCD Indicator with Pushbuttons

Indicator provides:

  • Two Lines: Five numeric characters on the top line (four when a minus sign is needed); and seven alphanumeric characters on the bottom line.
  • Measurement readout: Value displayed on the top line and a units label displayed on the bottom line.
  • Configuration and calibration prompts.

Two pushbuttons provide the following configuration and calibration prompts:

  • Zero and Span settings, noninteractive to automatically set output to either 4 mA or 20 mA using the “NEXT” and “ENTER” pushbuttons.
  • 4 and 20 mA Jog Settings, allowing the user to easily increment the mA output signal up or down in fine steps to match a value shown on an external calibrator.
  • Forward or Reverse Output
  • Damping Adjustment
  • Enable/Disable Optional External Zero
  • Temperature Sensor Failure Strategy
  • Failsafe Action (High or Low)
  • Units Label (Bottom Line of Display)
  • Settable Lower and Upper Range Values for Transmission and Display (Top Line)
