Honeywell SmartLine STD800 Differential Pressure Transmitter (STD820 Model)
Product Introduction
The Honeywell SmartLine STD800 Differential Pressure Transmitter (STD820 model) is a high-performance industrial instrument designed for precise pressure measurement in demanding applications. Leveraging piezoresistive sensor technology with on-chip static pressure and temperature compensation, it delivers exceptional accuracy (up to 0.025% of span) and stability (0.01% of URL per year for 15 years). Part of the SmartLine family, it ensures seamless integration with Experion PKS systems and complies with SIL 2/3 safety standards. The transmitter’s 400:1 rangeability and 90ms response time make it ideal for process control, flow measurement, and liquid level monitoring in oil & gas, chemical, and pharmaceutical industries.
