ST 3000 Smart Pressure Transmitter, Series 900 Gauge Pressure Models

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. ST 3000 Series 900 gauge pressure transmitters continue to bring proven smart technology to a wide spectrum of pressure measurement applications. Typical applications include high-pressure measurement in boilers, fuel feeds, and high-pressure reaction vessels in the petrochemical and hydrocarbon recovery industries - any location where accuracy and reliability are crucial to safe, economical operation. As with the rest of the line of Honeywell transmitters, the in-line transmitters offer the ability to be installed in a wide variety of hazardous environments for accurate repeatable pressure 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

Features:

• Six common models of dual-head and in-line gauge pressure transmitters from 500 psi to 10,000 psi are available for application.
  • STG944            0 to 500 psi       0 to 35 bar
  • STG94L            0 to 500 psi       0 to 35 bar
  • STG974            0 to 3000 psi     0 to 210 bar
  • STG97L            0 to 3000 psi     0 to 210 bar
  • STG98L            0 to 6000 psi     0 to 415 bar
  • STG99L            0 to 10000 psi    0 to 690 bar
• Choice of linear or square root output conformity is a simple configuration selection.
• Direct digital integration with Experion and other control systems provides local measurement accuracy to the system level without adding typical A/D and D/A converter inaccuracies.
• Unique piezo-resistive sensor automatically compensates input for temperature.  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, startup and ongoing maintenance functions.
