Guide
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 Remote Seal
Transmitters continue to bring proven
“smart” technology to a wide spectrum
of pressure measurement applications.
For applications in which the
transmitter must be mounted remotely
from the process, Honeywell offers the
remote seal line of gauge, absolute and
differential pressure transmitters.
Typical applications include level
measurement in pressurized vessels in
the chemical and hydrocarbon
processing industries. A second
application is flow measurement for
slurries and high viscosity fluids in the
chemical industry. Honeywell remote
seal transmitters are available with
secondary fill fluids for corrosive or high
temperature process fluids
All ST 3000 transmitters can provide a

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

—Series 900 Remote Seal Pressure Transmitters feature proven
piezoresistive sensors and advanced seal technology with standard weld
connections.
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.”

Summary
34-ST-03-57 Page 2 Description of Diaphragm Seals Diaphragm seals are traditionally used when a standard pressure transmitter should not be exposed to the process pressure directly. Diaphragm seals typically protect the pressure transmitter from one or more damaging aspects of the process media. Con...
