Pneumotrace II Respiration Belt with BNC Connector

The Pneumotrace II is a solid-state, piezo-electric respiration transducer without the need of a supply voltage (self-exciting). It generates and outputs a voltage signal between 20 to 100 mV (typical nominal output is 20-40mV) in response to changes in thoracic or abdominal circumference. The voltage response is linear to changes in transducer elongation.

The size of the respiration transducer itself is 28cm x 2.5cm x 0.3cm and comes with a 122cm belt strap which can allow a stretch of up to 250cm. It comes pre-assembled to a 3m connection cable and a male BNC connector.

Pneumotrance II respiration belts can be used with almost any biosignal amplifier with a BNC connector. They are commonly used with ADIstruments (ADI) biosignal amplifiers.
