Superior Sensor Technology (Los Gatos, California) today announced its CP301 — a four-port, dual pressure sensor for PAP devices.

The CP301 integrates a gauge pressure sensor and a differential pressure sensor into a small package with dedicated ports for each sensor. The result, according to the company, could make it easier and more cost-effective to design accurate and flexible PAP machines for sleep apnea, COPD, asthma and home ventilator applications. It could improve airflow and air pressure capability in continuous positive airway pressure (CPAP), bi-level PAP (BiPAP) and automatic PAP (APAP) devices.

The CP301’s characteristics also include:

  • Both integrated sensors have accuracy within 0.05% of the selected pressure range, total error band within 0.15% of FSS and long-term stability within 0.15% of FSS per year. This accuracy is due to the architecture’s very low noise floor, which ensures that noise caused by fans or motors does not cause errors that could disrupt the therapy.
  • The CP301 has a 2 millisecond response time, enabling the PAP machine to quickly adjust the airflow based on apnea events.
  • Each of the pressure sensors in the CP301 includes four factory-calibrated pressure ranges, and there are four selectable bandwidth filters, enabling the device to support 64 configurations.

“Expanding our CP Series product line to include a dedicated four-port option will further simplify the design and improve the performance and flexibility of PAP devices, which greatly enhances the quality of life for people suffering from sleeping disorders,” said Anthony Gioeli, VP of marketing at Superior Sensor Technology.

Limited quantities of the CP301 are presently available directly from Superior Sensor Technology. Production volumes will be available at the end of Q2, with immediate delivery from Digi-Key Electronics and Mouser Electronics.
