Honeywell SmartLine STD800 Differential Pressure Transmitter (STD820 Model)

The Honeywell SmartLine STD800 Differential Pressure Transmitter (STD820 model) is a high-performance industrial instrument designed for precise pressure measurement in demanding applications.

• Standard accuracy: 0.035% of span; optional: 0.025% of span for critical applications
• Long-term stability: 0.01% of URL per year over 15 years, reducing calibration needs

• Piezoresistive sensor with automatic static pressure and temperature compensation
• Rangeability: 400:1, enabling reliable measurement across wide pressure spans (-400 to 400 inH2O)

• Response time: as fast as 90ms for real-time process control
• Two-wire 4-20 mA output with HART protocol for seamless integration

• Integral Dual Seal design compliant with ANSI/NFPA 70-202 and ANSI/ISA 12.27.0
• World-class overpressure protection and SIL 2/3 certification for safety-critical systems

• Multiple local display options and external zero/span configuration
• Polarity-insensitive electrical connections and comprehensive on-board diagnostics

• Plugged Impulse Line Detection and Dual/Triple Calibration options (for HART/Fieldbus)
• Process head materials: 316 SS or carbon steel; aluminum housing (8.3 lbs/3.8 kg)
