ABRASIVE MATERIAL TRANSPORT HOSE WITH WEAR DETECTING SENSORS

摘要

The useful life of an abrasive material transport hose (10) can be maximized if the hose is repositioned at the first signs of internal wear. This is accomplished by disposing at least two wear sensing elements (17, 21), each at a specified distance from the inwardmost surface of the inner tube (12), and each monitoring a condition indicative o f wear of the hose (10) at its specified distance from the inwardmost surface of the inner tube. When the innermost wear sensing elemen t (17) implies wear, the hose can be repositioned to extend the useful life until the outermost wear sensing element (21) indicates wear requiring replacement of the hose.
