NPA Pressure Sensors for Respiratory Care


The NovaSensor Pressure Amplified (NPA) Sensor is a surface mount pressure sensor provided in a miniature size as a cost-effective solution for respiratory applications that require calibrated performance.

Housed in a 14-pin SOIC surface mount package, the NPA Series is available in gauge, absolute and differential pressure ranges with either mV, amplified analog or digital outputs. The sensor is intended for printed circuit board mounting and delivered in tape-and-reel for ease of manufacturing.

Features of Respiratory-Specific NPAs:

  • Surface-mountable
  • Differential, gauge, absolute and low pressure
  • Up to 5 PSI full scale
  • Output Options: Amplified Analog, Digital Serial (14bit), Digital I2C, Uncalibrated mV
  • On-chip temperature sensor in digital mode
  • Operating temperature range of -40°C to 125°C
  • Fast response
  • High accuracy



  • Ventilators
  • Oxygen Concentrators
  • Sleep Apnea (CPAP)
