Abstract

Вариант осуществления рассматриваемого изобретения направлен на разработку домкрата, включающего один или более тензодатчиков. Один или более тензодатчиков может быть размещен на домкрате, внутри домкрата или встроен в домкрат. При создании домкратом нагрузки или силы один или более материалов внутри домкрата испытывает деформации или перемещения в результате воздействия нагрузки. Один или более тензодатчиков применяются для измерения деформации или перемещения и, следовательно, измерения напряжения. Замеренное напряжение может применяться для определения величины нагрузки, приложенной со стороны домкрата. В варианте осуществления изобретения применяют множество тензодатчиков, и результаты измерений могут объединяться для определения приложенной нагрузки.
