High-precision column type weighing sensor

Abstract

The utility model relates to the technical field of weighing sensors, in particular to a high-precision column type weighing sensor, which comprises a sensor body, a bearing column and a lead fixedly connected to one side of the sensor body, the bottom end of the sensor body is fixedly connected with a supporting rod, the bottom end of the supporting rod is fixedly connected with a piston, the outer side of the piston is provided with a fixing cylinder, and the fixing cylinder is fixedly connected with the bearing column. A round hole communicated with the inner side of the fixing cylinder is formed in the top end of the fixing cylinder, a liquid inlet assembly is arranged on one side of the fixing cylinder, a first threaded groove is formed in the top end of the bearing column, and a bolt is spirally connected to the inner side of the first threaded groove. By arranging the sensor body, the bearing column, the wire, the supporting rod, the piston, the fixing cylinder, the round hole, the liquid inlet assembly, the oil inlet pipe, the fixing plate, the first liquid inlet hole, the reset spring, the sealing ball, the sealing plate, the second liquid inlet hole and the connector, the load borne by the bearing plate fixed to an object can be weighed.
