Abstract
Official abstract text for this publication.
Embodiments of a system that can detect leaks that occur in seals, and in one example, to seals found in a valve. In one embodiment, the system utilizes sensors that measure fluid properties of a sample volume proximate to the seal. The system can compare data from these measurements with data from a sample of a reference fluid (e.g., ambient air) to indicate the presence of working fluid in the sample volume. This result may indicate problems with the seal, e.g., degradation of the seal that is meant to prohibit the working fluid from migrating out of the valve.
First claim
Opening claim text (preview).
What is claimed is: 1. A system to detect leaks at a seal, said system comprising: a measurement region forming a sample volume that can receive working fluid from the seal; a sensor component spaced apart from the measurement region and coupled with the measurement region to receive a first fluid sample from the sample volume, the sensor component configured to receive a second fluid sample that is different from the first fluid sample so as to generate signals comprising data…
