ST3000 Series 900 - Gauge

STT3000

In 1983, Honeywell introduced the first smart pressure transmitter, the ST 3000®. In 1989, Honeywell launched the first all digital, bidirectional protocol for smart field devices.

Today, its ST 3000 Series 900  pressure transmitters continue to bring proven smart technology to a wide spectrum of measurement applications.

Honeywell absolute pressure transmitters are used in applications in which high accuracy in the vacuum range of pressure is needed to include low-pressure measurement in vacuum distillation columns, where energy savings are directly proportional to the vacuum in the column. Honeywell transmitters can be used in a wide spectrum of hazardous environments in perfect safety to provide proven, repeatable pressure measurements.

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.

Features

Honeywell’s high-performance ST 3000 S900 transmitters lead the industry in:

  • Stability = +/-0.01% per year
  • Reliability = 470 years MTBF

Functions

  • 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.
