CP Series
Dual pressure sensor for CPAP, BiPAP and APAP combining differential and gauge pressure sensors in one device
The CP Series sensor modules for positive airway pressure applications leverage the advanced NimbleSense™ architecture, offering exceptional dynamic range to deliver the industry’s highest-performing pressure sensing solutions for CPAP, BiPAP, and APAP devices. By integrating both differential and gauge pressure sensors within a single package, the CP Series supports four programmable pressure ranges for each embedded sensor, enhancing versatility.
This series offers the most advanced sensor integration by combining two cutting-edge piezoresistive sensing elements with integrated amplification, ADC, DSP, and processor intelligence, streamlining the integration process for device manufacturers. Utilizing floating-point technology and sophisticated digital processing, the CP Series delivers highly precise digital outputs, ensuring maximum accuracy and simplifying system development.
Available in both 3-port and 4-port configurations, the CP Series provides design flexibility while optimizing performance, reliability, and cost-effectiveness for the demanding positive airway pressure market.
