Abstract
The invention discloses a material touch signal generator, comprising a measuring arbor wheel, an elastic arbor wheel, an upper guiding arbor wheel, a spring, a material touch bar, magnetic steel, a bracket, a material touch bar bracket, a steel rope, a lower guiding arbor wheel, and the like. One end of the steel rope is circled around a wire wheel or a wound roll through the upper guiding arbor wheel and the measuring arbor wheel, and the other end is connected with a heavy bob at last through the elastic arbor wheel and the lower guiding arbor wheel. With the effect of the heavy bob, the material touch bar overcomes the acting force of the spring to move; when the front end of a material touch block is close to the material touch signal generator, the material touch signal generator sends material touch signal to a control unit; when the back end of the material touch block is close to a covered bob signal generator, the covered bob signal generator sends covered bob fault signal to the control unit. The generator has simple structure, integrated design and unitization use, and can be conveniently applied to various heavy bob detection type level gauging devices that can guarantee long-term, reliable and stable operation in very bad conditions.
