Estimating the term…
A sensor sleeve for use in detecting a failure in an article (e.g., a hydraulic hose), the sensor sleeve includes an insulator layer that separates two electrode layers. As such, the electrode layers deform to contact each other, which changes the impedance as measured across the electrode layers. The sensor sleeve is designed to change electrical impedance (resistance) due to fluid pressure initiating a hole through the sensor itself. The sensor sleeve will detect the fluid leak when the hole penetrates the sensor and brings the two elastic electrodes in contact with each other and/or the fluid, which when the fluid is conductive fluid, creates a signal path between the first electrode layer and the second electrode layer, which also changes the impedance as measured across the electrode layers.
A fluid system, comprising:
A method for detecting failure in an article of a fluid system, the article including an outermost surface having a sensor sleeve arranged over the outermost surface of the article, the method comprising:
