Abstract
The invention relates to a precision load cell with an elastic body comprising a base end, a load or force receiving part and two or more beams connecting said base end and said load or force receiving part. At least one of the beams constitutes a lever connecting the load or force receiving part and a flexible wall of a sensor cavity placed in the base end. The flexible wall is adapted for undergoing deformation as the result of a displacement of the load or force receiving part through an action of the lever, and the sensor means are adapted for measuring the deformation of the flexible wall or the strain in the flexible wall.
