MOBILE SYSTEM OF ELECTRIC MEASUREMENT DEVICE Russian patent published in 1999 - IPC

Abstract RU 2143118 C1

FIELD: measurement technology. SUBSTANCE: proposed structure of mobile system of electric measurement device has two spiral springs employed to create counter-torque. Layers of electret are deposited on turns of springs to enhance their vibration stability. Charges of electret on each of two sides of adjacent turns facing each other have opposite signs. EFFECT: high vibration stability and reliability. 2 dwg
