Abstract
The present invention relates to a hose line (1) for transporting abrasive media with an electrically conductive reinforcing element (5) running in or on the hose wall (2) and extending in the hose direction (6), wherein an insert (7) made of electrically conducting material is at least partially embedded in the hose wall (2) and extends in the hose direction (6) at a distance from the reinforcing element (5).
Claims19
A method of preparing a hose line for use in a monitoring system for monitoring the state of the hose line, wherein the hose line is configured to transport abrasive media along a hose direction, and wherein the hose line includes a hose wall, an electrically conductive reinforcing element running in or on the hose wall and extending in the hose direction, and an insert made of electrically conducting material, said method comprising the steps of:
- (a) at least partially embedding the insert in the hose wall such that the insert extends in the hose direction at a distance from the reinforcing element;
- (b) at a first end of the hose line, connecting a first end of the reinforcing element and a first end of the insert to an electrical ohmmeter or continuity tester;
- and
- (c) at the second end of the hose line or on another section of the hose line, electrically connecting the reinforcing element and the insert to each other so that the reinforcing element, the ohmmeter or continuity tester, and the insert are integrated into an electric circuit.
Monitoring system for monitoring the state of a hose line, the system comprising:
- a hose line, wherein the hose line comprises a hose wall, an electrically conductive reinforcing element running in or on the hose wall and extending in a hose direction, and an insert made of electrically conducting material, wherein the insert is at least partially embedded in the hose wall and extends in the hose direction at a distance from the reinforcing element;
- and
- an electrical ohmmeter or continuity tester,
- wherein, at a first end of the hose line, a first end of the reinforcing element and a first end of the insert are connected to the electrical ohmmeter or continuity tester, and
- wherein the reinforcing element and the insert are electrically connected to each other at a second end of the hose line or on another section of the hose line so that the reinforcing element, the ohmmeter or continuity tester, and the insert are integrated into an electric circuit.
