COVID-19 Oxygen Concentrators: With over a decade as a supplier of pressure sensors to leading ventilator and respiratory manufacturers around the world, Amphenol All Sensors is rapidly responding to the COVID-19 Pandemic. Pressure sensors are critical components in the oxygen concentrators that provide necessary breathing assistance to patients battling COVID-19. 

Oxygen (O₂) concentrators deliver about five to 10 liters of oxygen per minute, typically at about 93% purity.  Unlike tanks or other containers supplying oxygen, concentrators use electrical pumps to provide a continuous supply of oxygen by removing the nitrogen from the surrounding air. To monitor the process and safely supply air to the patient, an oxygen concentrator uses differential pressure sensors for flow measurements and gauge pressure sensors for sensing pressure at different points in the process. The low differential pressure measurements for flow are typically only a few kPA.
