SleepSense Inductive Interface Cables allow you to connect any SleepSense Inductive Belt to your system. Designed as a plug and play replacement for Piezo Effort Sensors, the output of inductive bands is exactly proportional to the cross section area of the band's closed loop around the body. It is therefore changing as the patient breathes. The electronics in the interface box measure these inductance changes to generate an AC signal that is the most accurate and reliable replication of respiration waveforms. Designed for use with Alice 5 systems.
