Abstract
The invention relates to the field of a marine cable tension monitoring system and provides a cable tension sensor. The cable tension sensor comprises an elastomer 1, a protection plug 2, a protection cover 3, a transmitter 4, a cable conductor 5, a protection joint 6 and an end cover plate 7. The outer side wall of the sensor is provided with a spiral groove and an oil outlet. The lubricating oil flows out of the oil outlet to flow along the track of the spiral groove, so that a lubrication layer is formed on the outer surface of the sensor. Therefore, the circular friction interference is reduced, and the measurement accuracy is improved. At the same time, the outer side wall of the sensor is provided with a fixing groove, and a baffle block is inserted into the fixing groove. The sensor can be effectively fixed in location. As a result, the force applied on the sensor is ensured to be consistent in force vector direction. The measurement accuracy is further ensured.
