Abstract
A low pressure sensing device for sensing pressure changes in a pressurized gas storage bottle of an inflater. At least one wire is wrapped around the vessel to sense the expansion or contraction of the vessel due to pressure changes in the vessel. The wire has a first end and a second end. The first end of the wire is secured to the vessel and the remainder of the wire is free to move circumferentially relative to the vessel in response to the expansion and contraction of the vessel. This relative movement can be monitored to determine if a pressure change has occurred in the vessel.
