VN Series Pressure Sensors

Based on Superior Sensor Technology’s NimbleSense™ architecture, the VN series is a comprehensive set of pressure sensors for ventilator and high-flow oxygen devices. This family of products includes sensors for measuring inlet (wall and tank), flow, inspiratory, expiratory, and barometric pressures. The VN series utilizes Multi-Range^TM technology to create a wide 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 functionality, thus simplifying system development while adding manufacturing ease and increasing reliability.

With optional advanced digital filtering customization and a three-mode pressure switch, the VN series is more than a pressure sensor, it is a pressure-sensing subsystem.

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

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