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)Specifications:PTAF2- Sensor technology: differential pressure transducer- Jackbox connection: AC or DC- Output types: airflow and snore- Power source: 9 volt battery, alkaline- Cannula connector: dual female luer loks for cannula or line pressure- Size: 4.96" (126mm) x 2.76" (70mm) x .95" (24mm)- Weight: 130 grams (with battery)- Battery life: 1000 hours- Input pressure range: +/- 25 cm H2O- High level outputs (typical): 2.0V peak to peak (+/- 1V)- Low level outputs (typical): 600 µV peak to peak (+/- 300 µV)- Output cable connectors: varies by polygraph manufacturer- Output cable length: 7 ft.
