SmartLine® ST800 Differential Pressure Transmitters bring smart technology to a wide spectrum of measurement applications ranging from furnace combustion airflow rate to hydrostatic tank gauging.
SmartLine® ST800 Differential Pressure Transmitters bring smart technology to a wide spectrum of measurement applications ranging from furnace combustion airflow rate to hydrostatic tank gauging.
ST800 Differential Pressure Transmitters are ideal for critical process loops and high-value applications such as custody transfer, and energy and material balances. Four models are available with the following ranges:
Ambient temperature: –40 to +85 °C (varies by model) per spec sheet.
Supply voltage: varies by communication:
HART: ~10.8 – 42.4 VDC
DE: ~15 – 49.3 VDC
Fieldbus: ~9 – 32 VDC
Wetted parts: typically 316L stainless steel.
Optional 15-year warranty available.
Proven compatibility with Honeywell Experion PKS control systems.
STD810: –10 to +10 inH₂O (–25 to 25 mbar)
STD815: –100 to +100 inH₂O (–249 to 249 mbar)
STD820: –400 to +400 inH₂O (–996 to 996 mbar)
STD830: –100 to +100 psi (–6.9 to 6.9 bar)
STD870: –3,000 to +3,000 psi (–207 to 207 bar)
High maximum allowable working pressure (depends on model): up to several thousand psi.
Comprehensive onboard diagnostics.
Integral dual-seal design for safety (meets ANSI/NFPA 70-202, ISA 12.27.0).
Overpressure protection.
Support for SIL 2 / SIL 3 for functional safety.
Optional “Plugged Impulse Line Detection” (PILD) to detect blocked impulse lines.
Optional dual / triple calibration (for HART & Fieldbus models).
Standard accuracy: up to ± 0.035% of span; optional: ± 0.025%.
Long-term stability: up to 0.01% of URL per year, for up to 15 years.
Very high rangeability: up to 400:1.
