Air Flow Sensor Intensive Care Ventilator Portable Ventilator.

Yuanben FS1031 flow sensor is based on the principle of thermodynamics to detect the flow of gas medium in the convection channel, with good accuracy and repeatability. It has built-in temperature sensor, each of which has a special temperature compensation calibration; at the same time,
it has linear analog voltage output, which is convenient to use. Sensor features:
   the latest generation MEMS sensor chip technology has high precision,
fast response speed,
   good repeatability, and can accurately measure the minimum flow.
   After full calibration and temperature compensation, it is mainly used in intensive care ventilator, portable ventilator.
