The utility model discloses a two-dimensional displacement sensor which is composed of a base plate, a rotating frame, an angle sensor and a linear displacement sensor. The rotating frame is a base ofthe two-dimensional displacement sensor; bolt holes are formed in a bottom plate, a linear displacement sensor and an angle sensor are jointly fixed to a seat plate, the seat plate is matched with arotating frame through two rotating shafts, the seat plate can rotate around the rotating shafts in a test, two adjusting screws are installed on the rotating frame, and the range of the circumferential angle can be adjusted by adjusting the extending lengths of the adjusting screws. The sensor is high in output sensitivity, good in linearity, small in size, light in self-weight, small in temperature drift and high in moisture resistance. The sensor can be matched with a corresponding instrument, and matched instruments in different forms can also be selected to meet other application requirements of metering, detection, adjustment, control and the like.
