Abstract [en]

Kibble Balance is a device that can measure the mass by using the magnetic force acting on a current carrying coil. The aim of this experiment is to construct and calibrate a Kibble balance, and use it to measurements of small masses. A PID-controller written in LabView program is developed to control the balance. The calibration of the balance is done in the velocity mode and the corresponding BL-term is measured BL = 6.5(2)x10-2 (T·m). The linear relation between the mass and the current through the coil is found mass(mg) = 6.2(3) x I (mA) .
