Product Details
MF5619-N-800-B-D-A Air Flow Sensor
- Sensing Technology:
- MEMS Thermal-D® Technology: Direct mass flow measurement without temperature/pressure
compensation, ensuring high accuracy in low-flow applications .
- Design Advantages:
- Nano-Coated Sensor Surface: Resistant to oil, water, and fouling, enhancing long-term
reliability .
- Wide Dynamic Range: 100:1 turndown ratio for precise measurement across varying flow
rates .
- Flexible Configuration:
- User-Configurable Parameters: Flow units (slpm/sccm), response time, and output scaling via
front-panel buttons or digital interface .
- Multi-Gas Support: Factory-calibrated for CO₂ (B suffix); supports custom gas
calibration (e.g., N₂, O₂) 18.
- Industrial: Process control, gas mixing, and semiconductor manufacturing.
- Medical: High-flow anesthesia machines and oxygen delivery systems.
- Analytical Instruments: Environmental monitoring and gas chromatographs.
