ST3000 Series 900 - Remote Seal

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

Two most common models of remote diaphragm seals transmitters are available for application.
- STR93D 0 to 100 psid 0 to 7 bar
- STR94G 0 to 500 psig 0 to 35 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 and static pressure(DP only). 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.
