Superior Sensor Technology today announced the VN Series pressure sensor family with proprietary oversampling technology and expanded dynamic range, enabling companies to quickly design and manufacture high-performance ventilators and high-flow oxygen devices to support a broader range of patient breathing demands. 

VN Series pressure sensors incorporate an advanced oversampling technique to effectively eliminate all noise outside the band of interest. Superior Sensor's proprietary oversampling technology also allows mechanical ventilators to use sensor outputs directly at full speed. This eliminates the oversampling of sensor outputs, which can slow down system response time by up to 10 times. 

The product family consists of seven new devices supporting a wide range of system applications, from measuring flow to inlet, inspiratory, expiratory, and barometric pressures. State-of-the-art digital processing significantly reduces the impact of system-level noise. Additionally, with 24-bit output resolution, advanced filtering, exceptional zero stability, and support for greater than 1 kHz update rate, the sensors have been designed to maximize system accuracy and reduce error rates, greatly benefitting patients in life-critical, respiratory situations. 

The VN026CM and VN131CM come with extreme resolution that further expands the effective sensor resolution, increasing the dynamic range of the sensors and further reducing the noise floor by an additional 20db. Representing the lowest noise floor in the industry, the VN026CM and VN131CM, for the first time, offer manufacturers single sensor solutions that support a broad range of breathing needs from neonates to adults. 

“Each sensor in the VN Series has industry-leading 24-bit output resolution and 12 kHz sample rate, improving patient synchrony with unparalleled levels of accuracy and responsiveness,” said Anthony Gioeli, Vice President of Marketing, Superior Sensor Technology. With the extreme resolution sensors, manufacturers can more easily design one ventilator to support all patients, from neonates to adults.” 

The sensors offer optional integrated capabilities such as advanced digital filtering and a 3-mode pressure switch. These features turn the pressure sensors into sensing sub-systems that streamline manufacturing and increase reliability. Each sensor in the VN Series has an identical footprint and is pin-compatible with the rest of the series, simplifying PCB layouts and enabling manufacturers to easily swap VN Series sensors for different applications.
