Abstract

PURPOSE: To measure the quantity of deterioration of a rubber hose, by inlaying electroconductive rubber in the rubber hose in its longitudinal direction so that the electroconductive rubber is exposed on the peripheral surface of the hose and by placing two fitting metal members in contact with the electroconductive rubber to measure the electric resistance.
CONSTITUTION: One or plural electroconductive rubber pieces are inlaid at appropriate width and depth in the peripheral surface of a rubber hose 1 depending on its thickness and diameter. Two metal members 3 are attached to the rubber hose. Connector coupling terminals 4 on the metal members 3 are connected to an electric resistance meter 7 through electric wires 6 to determine the change in the resistance of the hose 1. The degree of deterioration of the hose is determined from the change in the resistance. This facilitates the measurement of deterioration of a rubber hose attached to the complicated inside of a machine and enables automatic and continuous recording of the result of the measurement.
