Abstract
Изобретение относитс к силоизмерительной технике и может быть использовано в весоизмерительных устройствах и в системах автоматического регулировани технологическими процессами. Цель изобретени - повышение точности измерени . При воздействии на цилиндрический чувствительный элемент 1 раст гивающих усилий в поперечном сечении его по вл ютс продольные раст гивающие напр жени Σр, которые при положительной магнитострикции материала и магнитном поле Фтр, перпендикул рном Σр, обуслов т снижение магнитной проницаемости материала, магнитной индукции и потока ФТР. Суммарное изменение потокосцеплени обмоток 6 (измерительных) обусловит величину выходного сигнала датчика, пропорционального измер емому усилию раст жени . 4 ил.The invention relates to load-measuring equipment and can be used in weighing devices and in systems of automatic control of technological processes. The purpose of the invention is to improve the measurement accuracy. When a tensile force is exerted on a cylindrical sensing element 1, longitudinal tensile stresses Σ p appear in its cross section, which, with a positive magnetostriction of the material and a magnetic field F tr , perpendicular to Σ p , cause a decrease in the magnetic permeability of the material, magnetic induction and flow f TR . The total change in the flux linkage of the windings 6 (measuring) will determine the magnitude of the sensor output signal proportional to the measured tensile force. 4 il.
