Air Flow Sensor Medical with High-Precision Air Measurement

Product description

WNK3000 is specially designed for ventilator applications. It measures the flow of air, oxygen and other non-aggressive gases with superb accuracy. The special design in the air duct makes the pressure loss of the flow body passing through the sensor very low, making its performance suitable for various demanding application scenarios, such as medical ventilation and respiratory applications.
WNK3000 works with 5V power supply voltage and has
a digital I2C interface. The output value is internally
calibrated and temperature compensated.
It is connected by a thermal sensor chip and a
high-performance integrated 24-bit AD acquisition
CMOSCMOS microprocessor connection manager.

Application range

Medical, process automation, burner control, fuel cell control, spectroscopy, environmental
monitoring, laboratory.

Characteristic

* Low pressure loss

* Flow range: ± 200slm (bidirectional)

* Accuracy 1.5% reading (typical value)

* Full calibration and temperature compensation

* Zero drift

The gas flow is measured by the thermal sensor chip, which ensures a very fast signal processing time and has the best accuracy compared with similar products and has a bidirectional measurement function.
