Honeywell’s SmartLine ST 800 Pressure Transmitter

Pressure Transmitters for a Wide Range of Industrial Process Applications

SmartLine ST 800 pressure transmitters offer the following features:

• Accuracy of up to 0.025%
• Stability of 0.01% per year
• Onboard pressure and temperature compensation
• Modularity with field-replaceable units
• Unequaled display capabilities
• External zero, span and configuration capability
• 90ms response time
• Polarity-insensitive electrical connections
• Lifetime 15-year warranty
• Unique integration capabilities with Experion® systems
• Intuitive human machine interface (HMI).

ST 800 pressure transmitters provide comprehensive self-diagnostics to help maintain high uptime, meet regulatory requirements and attain high quality standards. Their broad 400:1 turndown ratio and modular design allow users to re-range or swap electronic modules, instead of having to stock transmitters with multiple ranges or electronic modules.

​ST 800 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 Experion PKS: This improves performance and provides other capabilities such as transmitter messaging, healthwatch diagnostic capabilities, maintenance mode indication, and tamper alarm/indication.

​ST 800 transmitters help users improve product quality, reduce operational and maintenance costs, and maintain greater operational flexibility. In addition, these transmitters offer proven measurements across a varied range of hazardous environments without compromising on safety.
