Description
Дл измерени усилий, возникающих, например, в режущей цепи горных мащин, используют устройства, содержащие емкостной датчик, включенный в колебательный контур задающего генератора с частотной модул цией.To measure the forces arising, for example, in the cutting chain of mining machines, devices are used that contain a capacitive sensor included in an oscillating circuit of a master oscillator with frequency modulation.
Предлагаемое устройство более совершенно, по сравне))ию с известными , так как оно обеспечивает возможность дистанционного измерени усилий без применени проводной св зи между генератором и приемником .The proposed device is more perfect, as compared to the known ones, since it provides the possibility of remote force measurement without the use of a wired connection between the generator and receiver.
Это достигаетс тем, что генератор вмонтирован в исследуемом элементе режущей цепи мащины и св зан радиоканалом с приемником, выходной сигнал с которого поступает на регистрирующий прибор, например , щлейф остиллографа.This is achieved by the fact that the generator is mounted in the studied element of the cutting chain of the machine and is connected by radio to the receiver, the output signal from which is fed to a recording device, for example, an OSTILLOGRAPHER.
На чертеже изображены электрическа схема генератора предлагаемого устройства (а) и схема его приемника (б).The drawing shows an electrical circuit of the generator of the device (a) and its receiver circuit (b).
Датчик сигналов представл ет собой малогабаритный частотномодулированный генератор 1, монтируемый непосредственно в исследуемую деталь. Чувствительным элементом датчика вл етс конденсатор 2 или магнитна система катушки. Конденсатор вмонтирован в тело исследуемой детали и измен ет, .в некоторых пределах, свою емкость в зависимости от деформаций последней. Изменение емкости конденсатора вызывает, в свою очередь, изменение частоты генератора J.The signal transducer is a small-sized frequency-modulated oscillator 1, mounted directly into the test piece. The sensing element of the sensor is a capacitor 2 or a coil magnetic system. The capacitor is built into the body of the investigated part and changes, within certain limits, its capacity depending on the deformations of the latter. A change in the capacitance of the capacitor in turn causes a change in the frequency of the generator J.
