Abstract

PURPOSE:To always remotely and continuously monitor the moving quantity of a cable laid at a place not permitting a person to go in and out or sunk under the water in the line direction thereof, by outputting the quantity of electricity of a rotary type displacement sensor to the outside of a hermetically closed container through the waterproof connector provided to the container. CONSTITUTION:When a cable 3 extends and contracts in the axial direction at the supply time of a current to the cable, the flange 20b of the moving quantity transmitting member fixed to the cable 3 moves. By this movement, the winding quantity of the second wire like body 19b as a rotation transmitting member around an external rotary body 18 with a magnet changes to rotationally drive the external rotary body 18 with the magnet. The rotation quantity of the external rotary body 18 with the magnet is transmitted to an internal rotary body 17 with a magnet and a rotary shaft 16a is rotated to output the electrical variable quantity corresponding to the quantity of rotation to the output terminal 16 of a rotary type displacement sensor. This output value is transmitted to an external measuring cable through a lead wire 22 and a waterproof connector 14.
