Abstract:
A hose for transporting abrasive material including an inner lining, a plurality of layers of reinforcement ply disposed over the inner lining, a first wear sensing element disposed in a first sensed layer at a first distance from the innermost surface of the inner lining, the hose characterized by:a second wear sensing element in a second sensed layer disposed at a second distance from the innermost surface of inner lining, the second distance being greater than the first distance; a second wear sensing device, connected to the second wear sensing element for providing an indication of propagation of a hose wear condition from the first sensed layer to the second sensed layer; the first wear sensing element comprises a first pair of sensor wires each having a first end extending to a first end of the hose and a second end extending to a second end of the hose; and the second wear sensing element comprises a second pair of sensor wires each have a first end extending to the first end of the hose and a second end extending to the second end of the hose; the second end of the first pair of sensor wires are connected to one another; and the second end of the second pair of sensor wires are connected to one another.
