COAXIAL TYPE ELECTRONIC BALANCE

摘要

PROBLEM TO BE SOLVED: To provide a low-priced, high-precision electronic balance which eliminates high-precision processing of machined parts such as a knife edge and by deleting a supporting point, a weight point, a force point, and a Roberval mechanism connecting the three points, and which eliminates experienced skills by simplifying assembly processes. ;SOLUTION: The coaxial type electronic balance has a sample suspending hook 3, a driving coil 7, a differential coil 8, and a core 9 which are coaxially placed on the force point. The supporting point part is a perfectly fixed torsion balance system provided with a piano wire 10 under a predetermined tension. The electronic balance also has weight-point balance tare correcting weights 5, 6.;COPYRIGHT: (C)2003,JPO
