NPA pressure sensor series for sleep apnea devices

Sleep apnea is a common disease that affects millions of people all over the world, and if left undiagnosed and untreated can cause serious health complications. GE Sensing & Inspection Technologies (NYSE: GE) has developed the Nova Pressure Amplified (NPA) series of pressure sensors for medical devices. Small and effective, the NPA is a critical component in creating cost-effective sleep apnea monitors that are more accurate and reliable than those currently on the market.

“The NPA pressure sensor series ensures that new sleep apnea and respiratory monitors have the best price performance available for critical care and home-use markets,” said Brian Wirth, Global Product Manager at GE Sensing & Inspection Technologies.

The NPA series provides a cost effective solution for medical applications that require calibrated, accurate and stable pressure measurement in one of the smallest packages available on the market today. The small size, position sensitivity and surface mount packaging help original equipment manufacturers (OEM) reduce external component costs, which improves overall system reliability. Key applications in addition to sleep apnea include respiratory medical devices, ventilators and anesthesia monitors for home and critical care use.

The NPA is available in tape and reel, ready for automated assembly, in pressure ranges from 0 to 10INH20 (inches of water) through 0 to 30 pounds per square inch (PSI), in gauge, differential and absolute versions, with manifold or barbed pressure connections. Best in class performance includes 60 times overpressure for 10INH20 ranges, mounting sensitivity is less than 0.3% full scale (FS) and position sensitivity less than 0.1%FS. Long-term stability is specified to be better than 0.1%FS per year.
