The invention discloses a tension monitoring sensor for eliminating a vibration peak value of elevator steel wire ropes. The tension monitoring sensor comprises an upper cover which is in movable fit with a telescopic pole of a hydraulic oil cylinder, a disk body which is in movable fit with a slide block, an oil cavity cylinder which is packaged by the upper cover and the disk body, wherein the upper cover is in threaded connection with the disk body and covers the disk body; the oil cavity cylinder is in threaded connection in the disk body; and a ring of copper rings used for sealing oil is arranged between the disk body and the oil cavity cylinder. The sensor is mounted between the slide block of a balancing and suspending device of a friction type elevator oil cylinder and the telescopic pole of the hydraulic cylinder; under the action of the tension of the steel wire ropes, the part, pasted with a strain gage, of the sensor generates elastic deformation to measure tension of each steel wire rope; and sum of tension of all steel wire ropes is total load hoisted by the elevator. The sensor is reasonable in structural design; influence of kick of stress caused by shaking, vibrating and the like of the steel wire ropes in an elevator working process can be eliminated, and tension of the steel wire ropes can be stably and accurately monitored in real time.
