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 100 Remote Seal Transmitters continue to bring proven “smart” technology to a wide spectrum of measurement applications. Typical applications include high accuracy level measurement in pressurized vessels in the chemical and hydrocarbon processing industries. A second application consists of accurate flow measurement for slurries and high viscosity fluids in the chemical industry. Honeywell remote seal transmitters demonstrate proven reliability in hundreds on installations in a wide variety of industries and applications with a wide variety of secondary fill fluids for corrosive or high temperature process fluids.
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 high-performance ST 3000 S100 transmitters lead the industry in:
•Accuracy
•Stability
•Reliability
•Rangeability
•Warranty
Includes Lifetime™ Transmitters:
•Total Accuracy = ±0.0375%
•Stability = ±0.01% per year
•Reliability = 470 years MTBF
•Rangeability = 400 to 1
•Lifetime Warranty = 15 years
Figure 1—Series 100 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. S100 transmitters are ideal for critical applications, such as custody transfer of natural gas and energy and material balances, where accuracy and stability are of the utmost importance.
"Our commitment to Honeywell field instruments is based on seamless integration with our Honeywell system and the enhanced fault detection that the Honeywell DE protocol offers. Honeywell instruments also offer us a better way of ensuring database integrity over simple analog instruments. In addition, Honeywell's high-quality support has enabled us to better implement solutions to some of our more difficult problems. We have used Honeywell differential pressure smart transmitters for the past eight years. Based on their accuracy and low failure rates, we are now targeting critical flow applications that require the robustness that these transmitters bring.”

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. Consideration for using a diaphragm seal should be made in the following circumstances.
•High Process Temperature
•Process Media is Viscous or Contains Suspended Solids
•Process Media is Subject to Solidifying
•Process Media is Corrosive
•Process Application Requires Sanitary Connections
•Process Application Subjects the Measuring Instrument to Hydrogen Permeation
•Tank Level Applications with Maintenance Intensive Wet Legs
•Tank Application with Density or Interface Measurements
•Measuring Instrument Requires Remote Mounting
The following diaphragm seals are standard from Honeywell (please call your local salesperson if you do not see the product you need for your application):
Figure 2 - Flush Flange Seals can be used with differential, gauge and absolute pressure transmitters and are available with 3” ANSI Class 150, ANSI Class 300 and DIN DN80-PN40 process connections. Flush flange seals can also be provided with Lowers. Lowers are essentially calibration rings, which allow flushing connections if needed – see Figure 31.

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.
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 in-field 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.
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.

|
NAMUR NE 43 Compliance |
Transmitter failure information is generated when the measuring information is invalid or |
Option |
no longer present. Failure information is transmitted as a current signal but outside the |
|
normal 4-20 mA measurement signal level. Transmitter failure values are: ≤ 3.6 mA and |
|
≥ 21.0 mA. The normal signal range is ≥ 3.8 mA and ≤ 20.5 mA. |
|
|
SIL 2/3 Compliance |
SIL certified to IEC 61508 for non-redundant use in SIL 2 related Safety Systems |
|
(single use) and for redundant (multiple) use in SIL 3 Safety Systems through |
|
TÜV Nord Sys Tec GmbH & Co. KG under the following standards: IEC61508-1: 1998; |
|
IEC 61508-2: 2000; IEC61508-3: 1998. |
