Устройство для замера амплитуд колебаний лопаток турбомашины дискретно-фазовым методом. Устройство содержит регистрационную и анализирующую аппаратуру МИК, периферийный, корневой датчики и датчик оборотной частоты. В этом устройстве сердечник периферийного датчика выполнен из ферромагнитного материала, поперечное сечение сердечника имеет форму вытянутого прямоугольника с отношением сторон 10 ≥ в/а ≥ 3, где а и в - соответственно ширина и длина поперечного сечения сердечника. Изобретение позволяет производить замеры колебаний рабочих лопаток, закрытых бондажными полками. При этом для замера тангенциальной и аксиальной составляющей амплитуды колебаний угол 30-60o между минимальной осью инерции сердечника периферийного датчика и осью турбины выбирается в диапазоне 30-60o а для замера только тангенциальной составляющей амплитуды угол 30-60o установки сердечника выбирается равным 0.A device for measuring the amplitudes of oscillations of the blades of a turbomachine by the discrete-phase method. The device contains registration and analyzing equipment MIC, peripheral, root sensors and a reverse frequency sensor. In this device, the core of the peripheral sensor is made of ferromagnetic material, the cross section of the core has the shape of an elongated rectangle with an aspect ratio of 10 ≥ w / a ≥ 3, where a and b are the width and length of the cross section of the core, respectively. EFFECT: invention makes it possible to measure oscillations of working blades closed by bondage shelves. In this case, to measure the tangential and axial component of the amplitude of the oscillations, the angle of 30-60 o between the minimum axis of inertia of the core of the peripheral sensor and the axis of the turbine is selected in the range of 30-60 o and for measuring only the tangential component of the amplitude, the angle of 30-60 o of the core installation is chosen equal to 0.
