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 Differential
Pressure Transmitters continue to bring
proven “smart” technology to a wide
spectrum of pressure measurement
applications, from furnace combustion
airflow rate to hydrostatic tank gauging.
The ST 3000 S900 Differential
Pressure Transmitter can be used with
any primary flow element to provide
proven, repeatable flow measurement.
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 Differential 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 and configuration capability between the operator and the
transmitter through several Honeywell field-rated portable configuration
devices, including the Smart Field Communicator (SFC) and the Multiple
Communication Configurator (MC ToolKit). While both are made for infield use, the MC Toolkit also can be ordered for use in intrinsically safe
environments.
®
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 down-line during commissioning.

Non-Sparking: Ex n IIC T6 (T4 with SM option)
Flame-Proof, Zone 1:
Pressure Equipment Directive
(97/23/EC)
EX d IIC T5
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).
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.

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
(Options ME and SM)
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
(Options HC and H6)
Optional electronics modules for
the ST 3000 that provides HART
protocol compatibility in either the
HART 5.x or 6.x formats.
Transmitters with a HART option
are compatible with any HART
enabled system that provides
either 5.x or 6.x format support.
FOUNDATION Fieldbus
(Option FF)
Equips transmitter with FF
protocol for use in 31.25 kbit/s FF
networks. See document 34-ST03-72 for additional information on
ST 3000 Fieldbus transmitters.
SIL2/SIL3 Certification
(Option SL)
This ST 3000 product is available
for use with safety systems. With
the SL option, we are fully certified
to SIL 2 capability for single
transmitters and SIL 3 capability for
multiple transmitter use through
TÜV Nord Sys Tec GmbH & Co.
KG.
We are in compliance with the
following SIL standards:
IEC 61508-1: 1998;
IEC 61508-2: 2000;
IEC 61508-3: 1998
NAMUR NE43 Compliance
(Option NE)
This option provides software the
meets the NAMUR NE43
requirements for failsafe software.
Transmitter failure information is
generated when the measuring
information is no longer valid.
Transmitter failure values are:
≤ 3.6 mA and ≥ 21.0 mA. The
normal ST 3000 ranges are ≤ 3.8
mA and ≥ 20.5 mA.
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.
