Mems Medical Air Flow Sensor Alternate to Honeywell Sensor Awm720p1, Medical Flow Sensor, Ventilator Flow Sensor

Introduction
The S400 series is fabricated using a micro-electromechanical system (MEMS) flow sensor chip. It is suitable for
the measurement of clean and relatively dry gases for various purposes. It realizes the digitization, intelligence and
high safety of the equipment, and has the innovation of traditional industries.
  Function and improvement; a wide range of flow ranges meet the flow measurement requirements of different equipment
in the industry. High sensitivity, high reliability, high stability and low cost performance characteristics can promote the industry
to develop energy-saving and intelligent.
  The S400 series is based on a MEMS flow sensing unit, high-precision digital processing and calibration circuit (MCU),
integrated high-resolution delta-sigma A/D converter and logic with internal calibration and MCU processor.
The sensing signal is effectively collected in real time, and the accurate flow signal is obtained, and the corresponding
compensation algorithm is processed internally, so that no external calibration compensation is required, and high-precision
flow output can be ensured; the friendly digital output communication mode can be used by the user. It is very convenient to get
the corresponding data information; the product application range is very broad.

1. Customizable range between 10SLM and 500SLM
2. SLM: Standard liters per minute. Standard conditions: 0 ° C and 1 atmosphere
3. In addition, the two-way airflow test can be customized, and the analog output is
    correspondingly changed. F(min)-F(max) corresponds to 1-5V output, and 0 flow
    corresponds to 3V;
4. Includes temperature drift and linearity error


Linear Output

1. The unidirectional airflow mode: (calculation formula)
Flow = [(VOUT -1 V) / 4 V] × full scale flow
For example: CAFS4103V has a full-scale flow of 200 SLM. When the output voltage is read at 2.5V,
the instantaneous flow rate is [(2.5V-1V) / 4V × 200 SLM] = 75 SLM
2. Two-way airflow mode: (calculation formula)
Forward flow = [(VOUT -3 V)/2 V] × full scale flow
Reverse flow = [(3 V- VOUT)/2 V] × full scale flow
