Measuring either tension load or strain in cables or rods by means of an electrical resistance wire which is mounted along a cable or a rod which can be subject to a tension load or strain. The wire is contained in a wrap around cover which is designed to protect the wire against aggressive agents. The wire is mounted along the cable or rod so that it undergoes a variation of its electrical resistance when the cable or rod is subject to a variation of tension load or strain. A measure of the variation in resistance in the wire determines the tension load or strain in the cables or rods. |
