  • First Dual Pressure Sensor for PAP Machines with Dedicated Ports for Measuring Patient Airway Pressure and System Flow


    Los Gatos, CA, May 31, 2022 - Superior Sensor Technology today announced the industry’s only 4-port, dual pressure sensor for Positive Airway Pressure (PAP) machines used in sleep apnea, COPD, asthma and home ventilator applications.  The new CP301 integrates a gauge pressure sensor and a differential pressure sensor into a very small package with dedicated ports for each sensor, making it easier and more cost effective to design highly accurate, flexible PAP devices.


    The CP301 pressure sensor greatly improves the airflow and air pressure capability in Continuous Positive Airway Pressure (CPAP), Bi-Level PAP (BiPAP) and Automatic PAP (APAP) devices.  Superior Sensor is the only company to integrate the gauge and differential sensors into one product with 3 dedicated ports on the top and 1 dedicated port on the bottom of the device.  This level of integration eliminates the need for a second physical sensor and reduces tubing and routing requirements in the device, which simplifies design, speeds time to market, reduces PCB space and lowers system costs.  The CP301 is also the industry’s only pressure sensor for PAP devices to support 64 configurations, making the system design more efficient and flexible.


    Based on the company’s NimbleSense™ System-in-a-Sensor Architecture, the CP301 offers additional performance characteristics that significantly increase the airflow and air pressure capabilities of the PAP machine to improve patient comfort and enhance overall user experience.


       Both integrated sensors in the CP301 have industry leading 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, ensuring noise caused by fans or motors does not cause errors that could disrupt the therapy.

       The CP301 has very fast 2 millisecond response time, providing timely feedback to the PAP machine to quickly adjust the airflow based on apnea events, maximizing patient comfort and machine efficiency. 

       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. This enables manufactures to design flexible PAP machines for a broad range of age groups and medical concerns.


    “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, Vice President of Marketing, Superior Sensor Technology.


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

    Onboard pressure sensors are used to control the trajectory and performance of UAVs. Superior Sensor Technology is offering two advanced pressure sensors for barometer applications that measure changes in atmospheric pressure to maintain stable altitude and Pitot tube applications for measuring air speed (still and moving air) in winged UAVs.

    The ND015A absolute pressure sensor for barometric applications and the ND005D differential pressure sensor for Pitot tube applications have industry leading 17-bit effective resolution, resulting in measurement accuracy of within 0.10% and 0.05%. The NimbleSense architecture ensures this accuracy is linear, enabling the pressure sensors to maintain consistent measurement readings regardless of the UAVs altitude or speed. Unlike other pressure sensors, the ND015A and ND005D have an integrated multi-order digital filter that blocks out noise caused by wind and mechanical components of the UAV, further eliminating measurement errors. System update rates from the sensors can be set as fast as 2.25ms, ensuring faster response time during changing flight conditions. The devices size, weight and power consumption are very small; 19mm x12.7mm (size), weight 3.5gm (weight) and 5mA (power consumption).

    “The demand for UAVs is surging, with forecasted growth of over 18% annually between 2022 and 2030 driven by a mix of commercial, industrial and military applications. This growth will demand ever more intelligent and efficient pressure sensors for flight accuracy,” said Anthony Gioeli, Vice President of Marketing, Superior Sensor Technology.

    Superior Sensor’s pressure sensors are based on the NimbleSense system-in-a-sensor architecture, which offers an unprecedented level of integration and performance. For example, the NimbleSense Multi-Range™ feature enables UAV manufacturers to use the same sensor across all of their product lines operating at different speeds and conditions. This unique capability reduces inventory stocking costs and manufacturing time.
