Load-cell scale for preventing eccentric error and incubator having the same

摘要

PURPOSE: A load cell scale and incubator using the same is provided to reduce measurement error cause due to the eccentricity of load and obtain an accurate measurement result of an object. CONSTITUTION: A load cell scale comprises a base plate(31); a load cell(35) having a lower end(35a) supported by the base plate, an upper end(35b) for receiving a vertical load, and a bent portion(35c) connected between the lower end and the upper end of the load cell; an upper plate(33) mounted onto the load cell, and where an object to be measured is mounted; and a guide unit for guiding the upper plate to move only in a vertical direction by preventing the upper plate from being inclined by the eccentricity of load caused due to the object to be measured. The guide unit includes a first guide member(36) arranged to be protruded from the base plate; and a second guide member(37) arranged to be protruded downward from the lower surface of the upper plate, such that the second guide member contacts the inner or outer sides of the first guide member and guides the upper plate to move in a vertical direction.
