Oxygen Concentrators

Oxygen concentrators are used to concentrate oxygen from a gas supply (typically ambient air) to assist patients in breathing who require higher levels of oxygen than the ambient air. SMI has a variety of highly accurate and reliable pressure sensors to measure the various pressures in oxygen concentrators to ensure proper outlet pressure to the patient, or air flow rate, or pressure in the compressor during the concentration process.
