About Foxboro Pressure Transmitters
Foxboro®
pressure transmitters combine field-proven, reliable
silicon strain-gauge sensor technology with simplified, durable packaging.
The Foxboro pressure transmitter family covers a broad range of pressure
and level uses; including differential, gauge, and absolute pressure, as well
as remote seal flanged level. Each pressure transmitter uses the same
innovative topworks packaging with modular intelligent electronics, which
greatly simplifies installation, operation, servicing, and spare parts
requirements.
Benefits
•  Reduced maintenance and long-term operating costs
•  Improved performance for greater production efficiency
•  Faster and less frequent calibration
•  Flexible mounting configuration for easier, less expensive installation
•  Rapid product delivery for on-time completion of scheduled procedures
Summary
Foxboro pressure transmitters combine
field-proven, reliable silicon strain-gauge
sensor technology with simplified, durable
packaging. The Foxboro pressure transmitter
family covers a broad range of pressure and
level uses; including differential, gauge, and
absolute pressure, as well as remote seal
flanged level.
Business Value
Foxboro digital transmitters flexible mounting
configurations and low-profile structures
offer superior performance for an easier
and less expensive installation. Improving
performance, reducing maintenance and
long-term operating costs allows for greater
boiler production efficiency.

Technical Challenge
Effective, profitable power plant operation requires managing capital-
expense turbine, boiler, and combustion equipment, along with many other
assets that must be precisely balanced. Reliable readings of pressure,
temperature, and other process variables are critical to success.
While analog transmitters are known for accuracy and reliability, maintenance
costs increase with age, and flexibility for performance improvement is limited.
To reduce long-term operating costs and maintain quality service to more
than 300,000 customers, a Michigan power utility launched a program to
replace its aging analog transmitters with modern digital models.
The utility uses transmitters for draft indications on the boiler and pulverized
mill area. They read pressure on the boiler and the turbine as well as
combustion and steam heating equipment. Some of the instruments send
data to a centralized distributed control system (DCS), which manages the
set points that control the sensitive interactions. Other instruments simply
indicate various pressure states to operators and maintenance technicians.
When this power utility implemented its first DCS, all transmitters were analog.
At the time, mixing and matching multiple brands of analog sensors was
difficult, and in some cases impossible, due to proprietary mounting configu-
rations. Managers at this Michigan power plant wanted to be certain that they
selected a digital sensor that would not lock them into a single vendor.

The Foxboro Solution
After evaluating transmitter suppliers, the utility selected Foxboro intelligent
instrumentation with standard mounting configurations. Foxboro’s ability to
guarantee quick delivery further supported the decision to purchase Foxboro
transmitters.
Thus far, Foxboro has supplied differential pressure and gauge pressure
transmitters to the power plant. The Foxboro IDP10 is an intelligent two-wire
differential pressure transmitter with high-performance accuracy to ±0.05
percent of calibrated span. The IDP10 provides measurement spans of 0.12
to 21000 kPa (0.018 to 3000 psi), which expands its versatility so that a single
transmitter can satisfy nearly all DP applications. The Foxboro IGP10 is a
two-wire transmitter for high-gauge-pressure applications to 52, 105, or
310 MPa (7500, 15000, or 30000 psi). Gauge pressure measurement spans
may be as low as 0.12 kPa (0.5 in H2
O) or as high as 35 MPa (5000 psi).
The Foxboro IDP10 and IGP10 pressure transmitters are available with 4 to
20 mA analog output, as well as HART, FOUNDATION Fieldbus, PROFIBUS,
and FoxCom communications protocol compatibility. These transmitters are
also available with industry-standard mounting configurations that make it
easier and less expensive to replace existing transmitters and reuse existing
installation designs without being limited to a single supplier, and are backed
with an industry-leading 5-year warranty.
Ease of calibration is another major benefit that the power utility receives,
since the Foxboro digital transmitters can be calibrated by using the push
buttons either on the digital transmitter’s LCD, a handheld communicator, or a
notebook/desktop computer; and can be calibrated from the operator station
of the DCS.

Results
The Foxboro transmitters standard mounting
configuration, which serves as a universal
replacement for all competitive models,
allows the power utility to change transmitters
without having to replace the entire manifold.
Likewise, if utility personnel need to replace
a transmitter and do not have the primary
vendor’s product available, they now have
the flexibility to use another brand.
The power utility has also realized increased
productivity resulting from less calibration.
With analog gauges, calibration was frequent
and time-consuming. The digital transmitters
require calibration considerably less often;
which is normally completed during forced
outages.
The ease of making routine calibrations has
had a true preventive maintenance benefit.
By being able to check and correct
calibration on every instrument during a
shutdown, plant operators are more confident
that all instruments will be operating at peak
performance once the system starts up.
The utility has also benefited from rapid
Foxboro order fulfillment. To take advantage
of a scheduled shutdown, utility managers
needed the first 90 transmitters within 4
days. Foxboro and the local representative
was committed to meeting their immediate
deadline — and delivered on their promise.
Last year, the utility installed an additional 90
or so transmitters; timing was even more of
an issue. Foxboro came through once again.
