023 - Impulse response pressure transducer
King J.
Abstract
A simple method for testing the pressure inside a sealed vessel without breeching the vessel wall is presented. The method is based on the impulse response of the vessel. For some pressure vessels, it is desirable to have a pressure transducer that does not breech the vessel wall. This is true for pressure vessels used in applications where it is desirable to have > 10 year shelf life. In these cases, the port required for a gauge would reduce the reliability of the system by creating a potential leak path. Pressure vessels containing highly corrosive materials are another application where it is desirable to have a pressure gauge with no wetted components. The theory and development of the pressure gauge is presented. Specific hardware implementations are demonstrated. The gauge is cost competitive with existing technology.
