The redefinition of the kilogram in 2019 has emphasized the need for precise measuring instruments such as the Kibble Balance, which directly compares an electromagnetic force to the weight of a test mass. This work investigates the development of a flexure-based mechanism for use in a high-precision…
We studied the anelastic aftereffect of a flexure being used in a Kibble balance, where the flexure is subjected to a large excursion in velocity mode after which a high-precision force comparison is performed. We investigated the effect of a constant and a sinusoidal excursion on the force comparison.…
A new Kibble balance is being built at the National Institute of Standards and Technology (NIST). For the first time in one of the highly accurate versions of this type of balance, a single passive flexure mechanism is used for both modes of operation: the weighing mode and the velocity mode. The mechanism…
