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 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 S100 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. Figure 1—Series 100 Differential Pressure Transmitters feature proven
piezoresistive sensor technology.

Pressure Equipment Directive The ST 3000 pressure transmitters listed in this Specification have no pressurized
(97/23/EC) 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.
