Product Summary
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 series utilizes Multi-RangeTM technology to create the industry’s widest dynamic range, eliminating the need for fine tuning or additional calibration.
- Eliminates 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. • Highest levels of accuracy and performance due to the architecture’s extremely low noise floor.
- 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. With the introduction of the VN Series, Superior Sensor Technology is taking resolution to the extreme! The product family has 24-bit output resolution, and we offer two extreme resolution sensors with approximately 18-bit effective resolution at high bandwidth. This is significantly higher than any other pressure sensors, and in critical high speed applications like ventilators, the difference is significant.
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.
