Details & Specs for Pro-Tech Pressure Transducer Airflow Sensors

We manufacture the PTAF2 and PTAF Lite pressure-based sensors, to generate accurate signals of respiratory airflow. Both products generate an accurate flow-based snore channel. The PTAF2 can be used in either AC or DC configurations and during nCPAP titrations. The PTAF Lite is a lightweight AC-only device most often used during diagnostic studies.

Features
- Discrete airflow and snore signals
- Gain control
- AC and DC compatibility
- Differential pressure ports (PTAF2 only)
