Springy-tensiometric scales that include load-receiving springy suspended platform, force-transfer element that is connected to platform in its center of rigidity, force-measuring indicator with output through indicator connected to microprocessor block for measurement and indication of mass and power supply block. Force-transfer element is arranged as two placed coaxialy permanent circular magnets and ball placed between those. The upper magnet is fixed in center of rigidity of platform and is supported due to attraction force, the lower magnet through calibrated elastic element is mechanically connected to power input of force-measuring indicator. Diameter of the ball is at least 20 % larger than the inner diameter of circular magnets tightened to each other through air gap. |
