Description
(54) ЭЛЕКТРОИНДУКТИВНЫЙ ДАТЧИК HEPI(54) ELECTROINDUCTIVE HEPI SENSOR
Изобретение относитс к области контрольно-измерительной техники и может быть использовано в станкостроении и машиностроении .The invention relates to the field of instrumentation technology and can be used in machine tool industry and mechanical engineering.
Известны электроиндуктивные датчики перемещений, содержащие каркасную многовитковую катушку с двум обмотками,например трапецеидальной формы и подвижный элемент, взаимодействующий с измер емый объектом.Electroinductive displacement sensors are known that contain a frame multi-turn coil with two windings, for example, a trapezoidal shape, and a movable element interacting with the object being measured.
Однако известные датчики имеют низкую чувствительность, узкий диапазон измерений и лишены поддипазонов, а включение дополнительных устройств дл получени регулируемых поддипазонов усложн ет датчик.However, the known sensors have a low sensitivity, a narrow measurement range, and are free of subbands, and the inclusion of additional devices for obtaining adjustable subbands complicates the sensor.
Предлагаемый датчик отличаес от известных тем, что дл расширени диапазона измерений в нем подвижный элемент выполнен в виде нескольких последовательно соединенных металлов с различной электропроводностью.The proposed sensor differs from the known ones in that in order to expand the measurement range in it, the movable element is made in the form of several series-connected metals with different electrical conductivities.
На чертеже показан описываемый .The drawing shows the described.
Первична обмотка I и вторична измерительна обмотка 2 расположены на трапецеидальной каркасе. Блок 5 обработки сигналов с обмотки датчика составлен из пластин металлов 4,5 с различной электропроводностью и толщиной.The primary winding I and the secondary measuring winding 2 are located on the trapezoidal frame. The signal processing unit 5 from the sensor winding is composed of metal plates 4.5 with different electrical conductivities and thicknesses.
Датчик представл ет собой каркасную многовитковую катушку j имеющую две системы витков: полесоздающие, т,е, возбуждающие вихревые токи в материале активном в электромагнитном отношении, и индикаторные, воспринимающие изменение электромагнитного пол . Полесоздающа обмо1ка I намотана на каркас,имеющий форму призмыt сечение которой, перпендикул рное оси,представл собой трапецию Со стороны рабочего торца датчика на том же каркасе намотана измерихельна Обмотка 2.The sensor is a frame multi-turn coil j having two systems of coils: field-creating, t, e, which induce eddy currents in the material active in the electromagnetic relation, and indicator, which perceive the change of the electromagnetic field. The wooded winding I is wound on a frame having a prism-shaped cross section of which, perpendicular to the axis, was a trapezoid. The measuring winding 2 is wound on the side of the working end of the sensor on the same frame.
Датчик подсоединен к стабшшзированному источнику переценного напр жени . Обмотка 2 подсоединена к блоку 5,The sensor is connected to a stabilized voltage source. Winding 2 is connected to block 5,
Датчик работает следующим образом.The sensor works as follows.
При относительном перемещении подвижного элемента вдоль каркаса датчика измен етс площадь перекрыти торца катушки,With the relative movement of the movable element along the sensor frame, the overlap area of the coil end varies,
что обуславливает (в зависимости от электропроводности пластин элемента) изменение выходного сигнала индикаторной катушки. При этом сигнал отображает дифференциально или интегрально площадь перекрытой части торца катушки.which causes (depending on the electrical conductivity of the element plates) a change in the output signal of the indicator coil. In this case, the signal displays differentially or integrally the area of the overlapped part of the end of the coil.
Измен зазор между подвижным элементом и рабочим торцом датчика , толщину пластин, составл ющих элемент, и их электропроводность.Change the gap between the movable element and the working end of the sensor, the thickness of the plates that make up the element, and their electrical conductivity.
можно варьировать чувотвительность и интервал измерений датчика.Sensitivity and measurement range of the sensor can be varied.
Экспериментальные и аналитические исследовани показали, что характеристики датчика строго линейны за исключением начального и конечного участков,Experimental and analytical studies have shown that sensor characteristics are strictly linear with the exception of the initial and final portions,
