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.

First claim

The invention claimed is:

1. 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 lea…
