Product Description
Honeywell SmartLine® STD800 Differential Pressure Transmitter
The Honeywell SmartLine® STD800 is a high-performance differential pressure transmitter designed for precise measurement of gases, liquids, and vapors. Part of the ST800 pressure family, this instrument excels in flow rate measurement (via orifice plate/venturi), level monitoring (closed/open tanks), and filter differential pressure applications across demanding industrial environments.
Core Applications & Industries
This differential pressure transmitter serves critical measurement functions in petrochemical, power generation, metallurgy, paper manufacturing, pharmaceutical, and water treatment industries.
Technical Specifications
Measurement Performance
  • Accuracy: Maximum ±0.025% of Range (URL)
  • Range Ratio: Up to 400:1 (STD820/830/870 models)
  • Long-Term Stability: ±0.01% URL/year with 15-year warranty
  • Response Time: 90ms (typical)
  • Static Pressure Influence: Automatic compensation reduces high-pressure errors
  • Overpressure Protection: Up to 210 bar protection against shock damage
Measuring Range by Model
