Description

The Crystal Trace® Piezo Respiratory Effort Sensor was designed to provide trouble free crystal clear tracing for respiratory effort during sleep studies. The sensor straps, with their low profile and stretch Velcro bands, make the system easy to install and exceptionally comfortable for all sizes of patients. Adult size is 1.5" wide and ranges from 28"(72 cm) to 80"(200 cm). Pediatric size is 1" wide and can be adjusted from 10.5"(27 cm) to 34"(86 cm).

Pediatric sizes available

Sensor Technology Piezo crystal film
Power Requirements No external power is required, signal is self generating
Typical Polygraph Settings Sensitivity: 2 - 30 uV/mm Low frequency filter/Time constant: .15 Hz or lower/1 second or longer High frequency filter: 15 Hz
Typical Signal Amplitude 600 microvolts peak to peak. Typical signal amplitudes may vary considerably. Response is dependent on such variables as sensor placement, patient airflow, sleep position, polygraph characteristics, etc.
Output Impedance Static (near DC): 750 KOhms Dynamic (.25 Hz): 600 Kohms Non-referenced, bipolar output
Standard Connector Type 1.5 mm touch-proof safety connector
Wire Length 7.0 feet
Note: Crystal Trace® effort sensors are non-referenced and produce bipolar microvolt level signals. Proper signal processing requires the use of AC coupled, referenced differential amplifiers
