SmartLine® ST700 Remote Diaphragm Seal Transmitters provide accurate measurement in a wide variety of applications involving corrosive or high-temperature process fluids.
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.
Uses piezoresistive sensor technology with on-chip temperature compensation for high accuracy and stability.
Supports static pressure & temperature compensation automatically.
Accuracy: up to ± 0.075% of span (standard) for many models.
Rangeability / Turndown ratio: up to 100:1.
STR73D / STR735D: –100 … +100 psig (–7 to +7 bar) span 1 … 100 psig (0.07 to 7 bar).
STR74G / STR745G: –500 … +500 psig (–35 to +35 bar) span 5 … 500 psig (0.035 to 35 bar).
