Flow Sensor for Anesthesia Machine Medical Module Sensor GFS131 for Medical Equipment

Flow Sensor for Anesthesia Machine Medical Module Sensor GFS131 for Medical Equipment

1. Product Features:

• Adopts the thermodynamic detection principle, which enables stable and reliable measurement of gas flow in the flow channel, ensuring accurate capture of flow rate changes.
• Equipped with a built-in temperature sensor; each sensor undergoes individual calibration for temperature compensation. This effectively reduces the impact of ambient temperature fluctuations on measurement results, maintaining high precision across the operating temperature range.
• Provides a linear analog voltage output (zero output: 0.45 - 0.55V; full-scale output: 4.34 - 4.66V). The linear output characteristic simplifies signal processing and integration with downstream control systems or data acquisition devices, lowering application complexity.
• Offers excellent measurement performance with high accuracy (±2.5% - ±4% F.S.) and good repeatability (±0.5% - ±1% F.S.), ensuring consistent and trustworthy flow data for critical application scenarios.
• Features a fast response time (standard 50ms, customizable to 15 - 1000ms). This allows the sensor to quickly detect sudden changes in gas flow, making it suitable for applications requiring real-time flow monitoring and feedback.
• Has a wide flow range option (standard 0 - 200 SLM, with other ranges like 100 SLM, 150 SLM, 300 SLM available). It can adapt to different gas flow measurement needs in various application scenarios, enhancing versatility.
• Operates with low power consumption (125mW at 5V working voltage) and low working current (25mA), which is beneficial for energy-saving requirements in portable or battery-powered equipment.

2. Product Applications:

• Primarily designed for medical equipment, especially intensive care ventilators and portable ventilators. In these devices, the GFS131 sensor accurately monitors the gas flow delivered to or exhaled by patients, providing essential data support for the ventilator’s control system to adjust ventilation parameters (such as tidal volume, respiratory rate) in real time, ensuring safe and effective respiratory support for patients.
• Can also be applied in other gas flow monitoring scenarios that demand high precision, fast response, and stable performance, such as certain industrial gas flow control systems, laboratory gas analysis equipment, or environmental gas sampling devices (depending on specific flow range and medium compatibility requirements).
