SmartLine® ST700 Differential Pressure Transmitters bring smart technology to a wide spectrum of measurement applications ranging from furnace combustion airflow rate to hydrostatic tank gauging.
SmartLine® ST700 Differential Pressure Transmitters bring smart technology to a wide spectrum of measurement applications ranging from furnace combustion airflow rate to hydrostatic tank gauging.
With better performance, modular construction, additional diagnostics and the best integration features, Honeywell SmartLine® transmitters help you reduce project costs and startup time, avoid unplanned downtime, improve product quality, reduce spare parts inventory and shorten time to repair. Helps you get the right instrument for your application. The tool enables error-free selection and validation of the instrument through efficient online collaboration. The tool documents your selection inputs and helps you share it with others. The ordered instrument arrives fully preconfigured, shortening commissioning time. Reduce costly wiring errors, troubleshooting and re work, saving valuable commissioning time.
Standard accuracy: ± 0.05% of span.
Optional accuracy: ± 0.04% of span.
Stability up to 0.02% of URL (Upper Range Limit) per year, over 10 years.
Static pressure compensation.
Quick Time Online
Temperature compensation on the sensor chip. Quick Time Online
Rangeability up to 100:1, meaning it can reliably measure very different spans.
