Description

33

потоки Ф и Ф: 3 детали перпендикул рны один к другому или близки к этому.flows F and F: 3 parts are perpendicular to one another or close to it.

Если к детали 8 Приложено раст гивающее усилие Р, то магнитна  проницаемость в направлении нриложени  усили  увеличиваетс , и магнитный ноток Ф,-.. , сцепленный с измерительными обмоткамИ, также увеличиваетс . В то же врем  магнитна  нрош-щаемость исследуемой детали 8 в нанравлепии, лерненднкул рном к приложенному усилию Р, уменьшаетс , а следовательно, уменьшаетс  и посто нный магнитный поток Ф, создаваемый обмоТКами 2 и 3, который нодмагничннает магнитонровод 6. Вследствие этого магнитна  проницаемость магнитопровода 6 на пути нотока 2 увеличиваетс . В результате магнитный ноток Ф татоке увеличиваетс  и наводит в измерительных облютках сигнал, соответствующий приложенному усилию Р и обусловленный одновременным изменением нсременного Ф,-.. и посто нного Ф магнитных потоков в исследуемой детали, что повыщает чувствительность датчика.If tensile force P is applied to part 8, then the magnetic permeability in the direction of application of the force increases, and the magnetic note F, - .. coupled with the measuring windings AND also increases. At the same time, the magnetic density of the investigated part 8 in nanowire, native to the applied force P, decreases, and consequently, the constant magnetic flux Φ generated by the magnetic flux 2 and 3, which magnetically magnetically conducts 6, is reduced. 6 in the path of the notok 2 is increased. As a result, the magnetic note F tatok increases and induces in the measuring envelopes a signal corresponding to the applied force P and caused by a simultaneous change in the current F, - ... and constant F magnetic fluxes in the part under study, which increases the sensitivity of the sensor.
