Description Features
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.
• 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.
