Introduction
In 1983, Honeywell introduced the first
Smart Pressure Transmitter― the ST
3000®. In 1989, Honeywell launched
the first all digital, bi-directional protocol
for smart field devices. Today, its
ST 3000 Series 900 Flange-mount
Pressure Transmitters continue to bring
proven “smart” technology to a wide
spectrum of pressure measurement
applications. Flange-mount
transmitters are offered with a variety of
tank connections including ANSI
flanges. Applications include gauge
pressure measurement in pressure
vessels in the chemical industry as well
as level applications in both the
chemical and hydrocarbon processing
industries with either wet or dry legs on
the low side. Versatility is made
possible though compound
characterization of the meter body as
well as the ability to measure a broad
range of differential pressures.
All ST 3000 transmitters can provide a
4-20 mA output, Honeywell Digitally
Enhanced (DE) output, HART* output,
or FOUNDATION™ Fieldbus output.
When digitally integrated with
Honeywell’s Process Knowledge
System™, EXPERION PKS™,
ST 3000 instruments provide a more
accurate process variable as well as
advanced diagnostics.
Honeywell’s cost-effective ST 3000
S900 transmitters lead the industry in
reliability and stability:
•
•
Stability = +/-0.01% per year
Reliability = 470 years MTBF
Figure 1—Series 900 Flange Mounted Pressure Transmitters feature proven
piezoresistive sensor technology.
The devices provide comprehensive self-diagnostics to help users
maintain high uptime, meet regulatory requirements, and attain high
quality standards. S900 transmitters allow smart performance at
analog prices. Accurate, reliable and stable, Series 900 transmitters
offer greater turndown ratio than conventional transmitters.
"Honeywell transmitters operating in the digital mode using
Honeywell's Digitally Enhanced (DE) protocol make diagnostics
available right at the control system's human interface. Equally
important, transmitter status information is continuously displayed to
alert the operator immediately of a fault condition. Because the
process variable (PV) status transmission precedes the PV value, we
are guaranteed that a bad PV is not used in a control algorithm. In
addition, bi-directional communication provides for remote transmitter
configuration directly from the human interface, enabling management
of the complete loop.”

Description
The ST 3000 transmitter can replace any 4 to 20 mA output transmitter in
use today and operates over a standard two-wire system.
The measuring means is a piezoresistive sensor, which actually contains
three sensors in one. It contains a differential pressure sensor, a
temperature sensor, and a static pressure sensor.
Features
•
Choice of linear or square
root output conformity is a
simple configuration
selection.
•
Direct digital integration with
Experion PKS and other
control systems provides local
measurement accuracy to the
system level without adding
typical A/D and D/A converter
inaccuracies.
•
Unique piezoresistive sensor
automatically compensates
input for temperature and
static pressure. Added
“smart” features include
configuring lower and upper
range values, simulating
accurate analog output, and
selecting preprogrammed
engineering units for display.
•
Smart transmitter capabilities
with local or remote
interfacing means significant
manpower efficiency
improvements in
commissioning, start-up, and
ongoing maintenance
functions.
Microprocessor-based electronics provide higher span-turndown ratio,
improved temperature and pressure compensation, and improved
accuracy.
The transmitter’s meter body and electronics housing resist shock,
vibration, corrosion, and moisture. The electronics housing contains a
compartment for the single-board electronics, which is isolated from an
integral junction box. The single-board electronics is replaceable and
interchangeable with any other ST 3000 Series 100 or Series 900 model
transmitter.
Like other Honeywell transmitters, the ST 3000 features two-way
communication between the operator and the transmitter through our
Smart Field Configurator (SFC). You can connect the SFC anywhere that
you can access the transmitter signal lines.
The SCT 3000 Smartline® Configuration Toolkit provides an easy way to
configure instruments using a personal computer. The toolkit enables
configuration of devices before shipping or installation. The SCT 3000
can operate in the offline mode to configure an unlimited number of
devices. The database can then be loaded downline during
commissioning.

Approval Bodies
- Hazardous Areas
Pressure Equipment Directive
(97/23/EC)
The ST 3000 pressure transmitters listed in this Specification have no pressurized
internal volume or have a pressurized internal volume rated less than 1,000 bar
(14,500 psig) and/or have a maximum volume of less than 0.1 liter. Therefore, these
transmitters are either; not subject to the essential requirements of the directive
97/23/EC (PED, Annex 1) and shall not have the CE mark, or the manufacturer has
the free choice of a module when the CE mark is required for pressures > 200 bar
(2,900 psig).
•
Flush design only.
NOTE: Pressure transmitters that are part of safety equipment for the protection of piping (systems) or vessel(s) from
exceeding allowable pressure limits, (equipment with safety functions in accordance with Pressure Equipment Directive
97/23/EC article 1, 2.1.3), require separate examination.
Attention: Dotted area indicates use
with closed tank with reference leg.

Options
Mounting Bracket
The angle mounting bracket is
available in either zinc-plated
carbon steel or stainless steel and
is suitable for horizontal or vertical
mounting on a two inch (50
millimeter) pipe, as well as wall
mounting. An optional flat mounting
bracket is also available in carbon
steel for two inch (50 millimeter)
pipe mounting.
Indicating Meter
(ME and SM Options)
Two integral meter options are
available. An analog meter (option
ME) is available with a 0 to 100%
linear scale. The Smart Meter
(option SM) provides an LCD
display for both analog and digital
output and can be configured to
display pressure in pre-selected
engineering units.
Lightning Protection
(Option LP)
A terminal block is available with
circuitry that protects the
transmitter from transient surges
induced by nearby lightning strikes.
HART Protocol Compatibility
(Option HC)
An optional electronics module is
available for the ST 3000 that
provides HART Protocol
compatibility. Transmitters with the
HART Option are compatible with
the AMS System. (Contact your
AMS Supplier if an upgrade is
required.)
Indicator Configuration
(Option CI)
Provides custom configuration
of Smart Meters.
Tagging (Option TG)
Up to 30 characters can be added
on the stainless steel nameplate
mounted on the transmitter’s electronics housing at no extra cost.
Note that a separate nameplate on
the meter body contains the serial
number and body-related data. A
stainless steel wired on tag with
additional data of up to 4 lines of 28
characters is also available. The
number of characters for tagging
includes spaces.
Transmitter Configuration
(Option TC)
The factory can configure the
transmitter linear/square root
extraction, damping time, LRV,
URV and mode (analog/digital) and
enter an ID tag of up to eight characters and scratchpad information
as specified.
Custom Calibration and ID in
Memory (Option CC)
The factory can calibrate any range
within the scope of the transmitter’s
range and enter an ID tag of up to
eight characters in the transmitter’s
memory.
