Stay wire sensor stroke limiting and distance monitoring device

The utility model relates to the technical field of stay wire sensors, and particularly discloses a stay wire sensor stroke limiting and distance monitoring device which is arranged on the upper portion in a shell of a stay wire sensor and located on one side of an encoder and comprises a bottom plate, a transmission assembly, a limiting assembly and a monitoring assembly, and the transmission assembly, the limiting assembly and the monitoring assembly are all arranged on the bottom plate. The transmission assembly transmits rotating force of a driving gear of the stay wire sensor to the limiting assembly and the monitoring assembly, and the limiting assembly and the monitoring assembly are both electrically connected with a controller of the stay wire sensor. The device is additionally arranged in an original stay wire sensor shell, the structure of the original stay wire sensor is not changed, the additional manufacturing process and cost are not increased, meanwhile, the stroke displacement of the stay wir
