Pressure Transmitters
Pressure Transmitters ST 3000 transmitter can replace any 4 to 20 mA output transmitter in use today and operates over a standard twowire system.
Honeywell’s ST 3000 Series 900 Gauge Pressure Transmitters are ideal for applications such as high-pressure measurement in boilers, fuel feeds and high-pressure reaction vessels in the petrochemical and hydrocarbon recovery industries or in any location where accuracy and reliability are crucial for safe and economical operations.
ST 3000 Series 900 Gauge Pressure Transmitters offer users the option to choose between dual-head and in-line models to match their process interface requirements. Six common models of the transmitters ranging 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
These cost-effective transmitters offer:
-
Stability = +/-0.01% per year
-
Reliability = 470 years MTBF
Honeywell ST 3000 Series 900 Gauge Pressure Transmitters
Description
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 transmitters.
Features
• 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.
• Smart transmitter capabilities with local or remote interfacing means significant manpower efficiency improvements in commissioning, start-up, and ongoing maintenance functions.
