Ventilator Pressure Sensor: VN025CM

Based on Superior’s NimbleSense™ architecture, the VN Series is a comprehensive set of pressure sensors for ventilator and high-flow oxygen devices. The family of products includes sensors for measuring inlet (wall and tank), flow, inspiratory, expiratory, and barometric pressures. The VN Series utilizes Multi-RangeTM technology to create the industry’s widest dynamic range, eliminating the need for fine-tuning or additional calibration. 

The VN Series combines an advanced piezoresistive sensing element with integrated amplification, ADC, DSP, and a digital interface. Advanced digital processing enables new functionality, thus simplifying system development, adding manufacturing ease, and increasing reliability. 

With optional advanced digital filtering customization and a 3-mode pressure switch, the VN Series is more than a pressure sensor – it is a pressure-sensing sub-system. 

Finally, the VN Series eliminates the need for the ventilator to oversample sensor outputs, as the sensor oversamples at 12kHz and includes internal bandwidth filters to provide a clean > 1kHz data rate. 

Constructed with a high-reliability plastic enclosure, the VN Series provides the ideal combination of very high performance and reliability while ensuring customers have a high volume, cost-effective solution optimized for ventilators and high-flow oxygen devices.
