Description
Изобретение относитс к проволочным тензодатчикам , определ ющим усили сжати и раст жени детали.The invention relates to wire strain gauges defining compressive and tensile forces of a part.
Известны проволочные тензодатчики сопротивлени дл определени усилий сжати и раст жени детали, содержащие рабочий и компенсационный чувствительные элементы из константановой проволоки с применением различных видов кле .Wire resistance strain gauges for determining the compressive and tensile forces of a part are known, which contain working and compensating sensitive elements made of constantan wire using various types of glue.
Дл повышени чувствительности, увеличени диапазона измерени , а также повышени устойчивости к агрессивным средам в описываемом тензодатчике рабочие и компенсационный элементы залиты полимеризованным эпоксидным компаундом. В состав эпоксидного компаунда входит эпоксидна смола ЭД-6 100 вес. ч., малеиновый ангидрид 30 вес. ч., дибутилфталат 12 вес. ч. и наполнители от О до 100 вес. ч.To increase the sensitivity, increase the measurement range, as well as increase the resistance to aggressive media in the described strain gauge, the working and compensation elements are filled with polymerized epoxy compound. The epoxy compound contains epoxy resin ED-6 100 weight. hours, maleic anhydride 30 wt. h., dibutyl phthalate 12 wt. hours and fillers from O to 100 weight. h
На чертеже изображен тензодатчик в разрезах .The drawing shows the strain gauge in the cuts.
Описываемый проволочный тензодатчик дл определени усилий сжати и раст жени детали , например, в железобетоне, в теле подпорной стены, платины, земл ного сооружени содержит крестообразную пластину / из эпоксидной смолы ЭД-6, на которую намотана константанова проволка 2, рабочими элементами. Под углом 90° к ней установлен компенсационный элемент 3 из той же. проволоки. От концов всех тензодатчиков выведены провода 4 на вторичные приборы. Все устройство залито и полимеризовано эпоксидным компаундом а из эпоксидной смолы ЭД6 . Датчик быть заделан в корпус.The described strain gauge for determining compressive forces and tension of the part, for example, in reinforced concrete, in the body of the retaining wall, platinum, earthworks contains a cross-shaped plate / of epoxy resin ED-6, on which the constantan wire 2 is wound, with working elements. At an angle of 90 ° to her installed compensation element 3 of the same. wire. From the ends of all strain gauges, wires 4 are connected to secondary devices. The entire device is filled and polymerized with epoxy resin a of epoxy resin ED6. Sensor to be embedded in the housing.
