SmartLine ST800 Pressure Transmitters

SmartLine ST800 pressure transmitters offer the following features:

• Accuracy of up to 0.025%

• Stability of 0.01% per year

• 80 ms response time

• Turndown ratios up to 400:1

• Automatic pressure and temperature compensation

• Modularity with field-replaceable units

• Comprehensive onboard diagnostic capabilities

• Unequaled display capabilities

• External zero, span and configuration capability

• Universal terminal electrical connections

• Integral Dual Seal design based on ANSI/NFPA 70-202 and ANSI/ISA 12.27.0

• Overpressure protection

• Compliance with SIL 2/3 requirements

• Unique integration capabilities with Experion® systems

• Intuitive human machine interface (HMI)

• 15-year warranty

ST800 transmitters can replace any 4-20 mA output transmitter in use today and operate over a standard two-wire system. Other features include:

• Three-in-one piezoresistive sensor that combines a differential pressure sensor, temperature sensor and static pressure sensor to deliver a fully compensated output signal
• High-performance microprocessor with integrated A/D converters that delivers faster response times, higher accuracy and better rangeability
• A range of output communication options, including 4-20 mA, Honeywell Digitally Enhanced (DE) protocol, HART and FOUNDATION Fieldbus
• Integration with the Experion control system: This improves performance and provides other capabilities such as transmitter messaging, healthwatch diagnostic capabilities, maintenance mode indication, and tamper alarm/indication.
