Differential Pressure Transmitters
Differential Pressure Transmitters Honeywell ST 3000 Series 900 provide a more accurate process variable as well as advanced diagnostics.
The ST 3000 Series 900 Differential Pressure Transmitters bring proven smart technology to a wide spectrum of pressure measurement applications, from furnace combustion airflow rate to hydrostatic tank gauging. The transmitters can be used with any primary flow element to provide proven, repeatable flow measurement.
Three most common ranges of ST 3000 Series 900 Differential Pressure Transmitters from 400” H2O to 3000 psi are available for application:
STD924 0 to 400 inH2O 0 to 1,000 mbar
STD930 0 to 100 psi 0 to 7,000 mbar
STD974 0 to 3000 psi 0 to 210,000 mbar
The transmitters provide comprehensive self-diagnostics to help users maintain high uptime, meet regulatory requirements and attain high quality standards. Accurate, reliable and stable, the transmitters offer greater turndown ratio than conventional transmitters.
In addition, the transmitters can be used in a wide spectrum of hazardous environments in perfect safety to provide proven, repeatable pressure measurements.
Honeywell ST 3000 Series 900 Differential Pressure Transmitters
The ST 3000 transmitter can replace any 4 to 20 mA output transmitter in use today and operates over a standard twowire system.
The measuring means is a piezoresistive sensor, which actually contains three sensors in one. It contains a differential pressure sensor, a temperature sensor, and a static pressure sensor.
Microprocessor-based electronics provide higher spanturndown ratio, improved temperature and pressure compensation, and improved accuracy.
The transmitter’s meter body and electronics housing resist shock, vibration, corrosion, and moisture. The electronics housing contains a compartment for the single-board electronics, which is isolated from an integral junction box.
The single-board electronics is replaceable and interchangeable with any other ST 3000 Series 100 or Series 900 model transmitter.
• Choice of linear or square root output conformity is a simple configuration selection.
• Direct digital integration with Experion PKS and other control systems provides local measurement accuracy to the system level without adding typical A/D and D/A converter inaccuracies.
• Unique piezoresistive sensor automatically compensates input for temperature and static pressure. Added “smart” features include configuring lower and upper range values, simulating accurate analog output, and selecting preprogrammed engineering units for display.
