Description

Дл  питани  дифференциальных индукционных вибродатчиков обычно примен ют ламповые генераторы, работающие стабильно только при наличии стабилизаторов, что осложн ет схему прибора.For the power supply of differential induction vibration sensors, tube generators are usually used that work stably only in the presence of stabilizers, which complicates the design of the device.

Предлагаемое устройство дл  замера вибраций, использующее дифференциальный индукционный вибродатчик, обеспечивает питание вибродатчика током стабильной частоты без усложнени  схемы устройства , что достигаетс  применением в схеме вибротрансформатора.The proposed device for measuring vibrations using a differential induction vibration sensor provides power to the vibration sensor at a constant frequency current without complicating the device circuit, which is achieved by using a vibration transformer in the circuit.

На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

Виброметр питаетс  от сети переменного тока 127-220 в, который подаетс  на трансформатор Т. Ток вторичной обмотки трансформатора TI выпр мл етс . Дл  сглаживани  выпр мленного тока в схему включен дроссель L. Сопротивление R нагрузочное. К сопротивлению Al присоединен вибротрансформатор Т. Вибротрансформатор TZ служит дл  преобразовани  посто нного тока в переменный ток частотой 435 гц. Конденсаторы Cj и Со совместно с первичной обмоткой вибротрансформатора Го образуют колебательный контур. Конденсатор Сз  вл етс  искрогасителем.The vibrometer is powered by an alternating current network of 127-220 volts, which is fed to the transformer T. The secondary current of the transformer TI is rectified. To smooth the rectified current, choke L is included in the circuit. Resistance R is load. A vibrating transformer T is connected to the resistance Al. The vibrating transformer TZ serves to convert direct current into alternating current with a frequency of 435 Hz. The capacitors Cj and Co together with the primary winding of the vibro-transformer G0 form an oscillating circuit. Capacitor C3 is a spark arrester.

Переменный ток частотой 435 гц подаетс  на дифференциальный индукционный вибродатчик Д, катущки Al и /(2 которого монтированы на трансформаторном железе, а  корь Я закреплен на сейсмической массе вибродатчика.An alternating current with a frequency of 435 Hz is supplied to a differential induction vibration sensor D, Al and / (for example, 2 rolls mounted on the transformer gland, and measles I mounted on the seismic mass of the vibration sensor.
