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
