MF4719-N6F-500-AB-A Flow Sensor For Oxygen Therapy Systems
Anesthesia Machines
Product Overview:
The MF4719-N6F-500-AB-A is a high-precision gas mass flow sensor
designed for industrial and commercial applications requiring
accurate flow measurement. It integrates advanced MEMS
(Micro-Electro-Mechanical System) technology to ensure reliable
performance across a wide range of gases and environmental
conditions. This sensor is ideal for applications such as medical
oxygen supply, industrial gas monitoring, and process control.
Product Features:
- High Precision: Utilizes MEMS thermal mass flow sensing technology
for accurate measurement across the full range.
- Wide Application: Supports dry, clean gases such as air, oxygen,
nitrogen, argon, and carbon dioxide.
- Fast Response: Enables real-time monitoring of flow variations,
critical for dynamic processes.
- Diverse Outputs: Offers RS485, 4–20 mA, and pulse outputs for
seamless integration with PLCs, SCADA systems, or data loggers.
- Robust Design: Built with corrosion-resistant materials and IP65
protection for harsh industrial environments.
- Low Pressure Drop: Minimizes energy loss in pipeline systems.
- User-Friendly Interface: Optional LCD display for real-time
visualization of flow rate and cumulative flow.
- Customizable Options: Supports tailored calibration, pressure
ratings, and mechanical interfaces.
Applications:
- Medical: Oxygen therapy systems, anesthesia machines.
- Industrial: Process gas control, compressed air monitoring,
petrochemical plants.
- Environmental: Air quality analysis, emissions monitoring.
- Food & Beverage: Carbon dioxide dosing in bottling lines.
