ELECTRONIC DIGITAL BALANCE Russian patent published in 2001 - IPC

FIELD: weight measurement technology intended for use in production facilities, in trade or at home for precise weighing of weights. SUBSTANCE: electronic digital balance includes weigh beam whose short arm is linked to load-taking platform and whose long arm is connected to mobile part of compensation unit. Electromagnet is used in the capacities of compensation unit and of transmitter of deviation of mobile part from balance. Electronic system incorporates generator of high-frequency current, narrow-band amplifier, detector, differential amplifier, reference voltage source, analog-to-digital converter, microcomputer, digital- to-analog computer, digital indicator and amplifier of compensation current. EFFECT: increased adaptability of balance to manufacture with preservation of high precision and basic servicing functions due to simplification of design of compensation unit. 1 dwg
