APPLICATION

Ventilator and Anesthesia Machine

The respiratory system is a very important life support system for the human body. The gas flow sensor, which is a key component for monitoring airflow velocity parameters, has been widely used in ventilators and plays an important role. From hospital bed oxygen supply, floor pipeline oxygen supply to oxygen generators, ventilators, anesthesia machines and other medical equipment needs the support of flow sensors.

Note:
①Provides any full-scale customization between 100SLM and 300SLM.
②SLM: Standard litre per minute, meaning that the standard situation rises per minute. The standard condition is as follows: gas temperature 20℃; Pressure 101.325 kPa;
③Response time customization can be provided between 10ms and 1000ms. This time refers to the electronic response time required by the flow sensor to any mass flow change from 10% to 90%, which may be affected by the aerodynamic interface.
④The real correction range of temperature compensation is 0-50℃, beyond which the effect of temperature compensation can not be guaranteed.
