Abstract
Изобретение относитс к измерительной технике и может быть использовано дл калибровки частотомеров с индукционными датчиками. Цель изобретени - повышение чувствительности. Плоский камертон, содержащий опору и две упругие ветви, снабжен двум массами, св занными с ветв ми и установленными с возможностью перемещени , причем одна из масс выполнена из ферромагнетика, а друга - из немагнитного материала. 1 ил.The invention relates to a measurement technique and can be used to calibrate frequency meters with induction sensors. The purpose of the invention is to increase the sensitivity. The flat tuning fork, containing a support and two elastic branches, is provided with two masses connected with the branches and mounted for movement, one of the masses made of a ferromagnet and the other of a nonmagnetic material. 1 il.

На черте-ке изображен резонатор Резонатор в виде кзмерюча включает опору 1 и уппугис ветни 2 и 3 с винтовой резьбой на концах Кэ резьбу навинчены массы 4 и 5 Масса л выполнена из ферромагнитного а втора масса 5 выполнена из немагнитного материалаThe drawing shows the resonator. The resonator in the form of a kzmeryuch includes a support 1 and a screw thread 2 and 3 with a screw thread on the ends of the Kе thread screwed on masses 4 and 5 Mass l is made of ferromagnetic and second mass 5 is made of non-magnetic material
В качестве ферромагнетика может быть вз 1Э например сталь а в качестве немагнитного материала - латунь керамика и т пAs a ferromagnet, it can be taken as 1E, for example steel, and as a nonmagnetic material, brass ceramics and so forth.
Резонатор работает в устройствах дл калибровки частотомеров с индукционными датчикамиThe resonator works in devices for calibrating frequency meters with induction sensors.
При поднесении датчика 6 к камертону он реагирует только на колебани массы 4 и не испытывает негативного вли ни колебании массы 5 за счет чего чувствительность к колебани м резко возрастает Навинчива и вывинчива массы 4 и 5 можно настраивать камертон на заданную частотуWhen the sensor 6 is brought up to the tuning fork, it reacts only to mass fluctuations 4 and does not experience the negative influence of mass fluctuations 5 due to which the sensitivity to oscillations increases dramatically Spinning and unscrewing masses 4 and 5 can adjust the tuning fork to a predetermined frequency
