Superior Sensor Technology CP303 & CP203 Dual Low Pressure Sensors
Superior Sensor Technology CP303 and CP203 Dual Low-Pressure Sensors are integrated with snore detection and feature a combined differential and gage sensor in one device. These sensors offer ultra-low noise, excellent long-term stability, and supply voltage compensation. The CP303 and CP203 sensors come with a standard I2C and SPI interface and are available in 3-port and 4-port configurations. These sensors provide a new level of integration into the PAP market by combining two piezoresistive sensing elements with integrated amplification, ADC, DSP, and processor intelligence. The CP303 and CP203 sensors are used in CPAP, BiPAP, and APAP applications.
