Description

(.54) СПОСОБ КОНТРОЛЯ СТЕПЕНИ УПЛОТНЕНИЯ БЕТОННОЙ СМЕСИ ПРИ ВИБРОФОРМОВАНИИ ИЗДЕЛИЙ(.54) METHOD FOR CONTROLLING THE DEGREE OF A CONCRETE MIXTURE WHEN VIBRATING A PRODUCT

разности фаз двух электрических сигналов, снимаемых с ввбродатчиков, установленных на вибростоле и на пригрузеphase difference of two electrical signals taken from the ground sensors installed on the vibrating table and on the weights

Фазовые измерени  обладают значительно большой точностью и помехоустойчи- I востЕаю, чем амплитудные, благодар  их применению достигаетс  высока  чувствительность и точность измерений.Phase measurements have significantly greater accuracy and noise tolerance than amplitude, due to their use, high sensitivity and measurement accuracy is achieved.

На чертеже показана одна из возможных схем практической реализации способа.The drawing shows one of the possible schemes for the practical implementation of the method.

Блок-схема включает вибродатчики 1, 2 установленные на вибростоле и пригрузе, усилители-ограничители 3, настроенные на частоту вибрации, и фазоизмерительный прибор 4, который выдает напр жение, пропоркциональное времени передачи вибрационных колебаний от одного вибродатчика к другому .The block diagram includes vibration sensors 1, 2 mounted on the vibration table and the load, amplifiers-limiters 3, tuned to the vibration frequency, and phase-measuring device 4, which provides a voltage proportional to the transmission time of vibration vibrations from one vibration sensor to another.
