Respiration Transducers
Pressure - Airflow / Snore
PIEZO PRESSURE FLOW/SNORE SENSOR
Model 14832
Isolated element provides excellent immunity to
environmental artifacts
Very strong and stable signal
Sturdy mechanical design


This sensor is designed to detect respiratory airflow and
snoring for recording onto a polygraph, EEG or similar type
of physiological recorder. The internal piezo crystal senses
minute pressure changes and filters them into two bands-
slow waves to the flow channel, and fast waves to the
snore channel.The sensor plugs directly into Grass AURA PSG systems via key connectors; no external power source is required. A nasal cannula is attached to the patient.
