Honeywell  ST 3000S 900 Smart Differential Pressure Transmitter

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. The 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 Experion® Process Knowledge System, 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
