Abstract
A system and method for detecting hose abrasion are disclosed. In one aspect, a hose abrasion monitoring system includes a hose assembly a monitoring circuit. The hose assembly includes a hose having at least one conductive layer and at least one outer insulating cover overlaying the at least one conductive layer. The monitoring circuit is in electrical communication with the at least one conductive layer. Upon abrasion of the at least one outer cover to expose a portion of the at least one conductive layer, the monitoring circuit is configured to detect electrical continuity between the at least one conductive layer and a conductive component external to the hose.
Claims20
A hose abrasion monitoring system comprising:
- a hose assembly including:
- a hose having at least one conductive layer and at least one outer insulating cover overlaying the at least one conductive layer;
- and
- a monitoring circuit in electrical communication with the at least one conductive layer;
- wherein the monitoring circuit is configured to detect electrical continuity between the at least one conductive layer, exposed by abrasion of the at least one outer insulating cover to expose a portion of the at least one conductive layer, and a conductive component external to the hose.
A method of monitoring abrasion of a hose assembly,
- applying a voltage across a monitoring circuit electrically connected between at least one conductive layer of the hose assembly and a conductive surface of a component, the at least one conductive layer being electrically insulated from the conductive surface;
- and
- measuring electrical continuity between the at least one conductive layer and the conductive surface.
A hose abrasion monitoring system comprising:
- a hose assembly including a hose having a conductive layer and an outer insulating cover;
- a fitting for fluidly connecting the hose and a component, the component having a conductive surface, the fitting including:
- a socket electrically connected to the conductive layer;
- and
- a nipple electrically connected to the conductive surface, the nipple being electrically insulated from the socket;
- a monitoring circuit electrically connected between the nipple and the socket;
- and
- a diagnostic unit having a sensor measuring electrical continuity between the socket and the nipple, thereby measuring electrical continuity between the socket and the conductive surface.
