Устройство предназначено дл преобразовани усилий в электрический сигнал и может быть использовано в качестве датчика усилий, веса в устройствах автоматического контрол различных технологических параметров в различных отрасл х промышленности , например в качестве датчика веса автоматических конвертерных весов.The device is intended to convert forces into an electrical signal and can be used as a force sensor, weights in automatic control devices of various technological parameters in various industries, for example, as a weight sensor of automatic converter weights.
Известные устройства дл измерени усилий, содержащие рабочие и компенсационные тензометрические преобразователи, трансформатор напр жени , трансформатор тока и измеритель тока, имеют малую чувствительность и низкую стабильность измерений .The known devices for measuring forces, containing operating and compensating strain gauge transducers, a voltage transformer, a current transformer, and a current meter, have a low sensitivity and low measurement stability.
В предложенном устройстве эти недоста ки устранены за счет того, что в нем тен зопреобразователи выполнены в виде лент, а один рабочий и один компенсационный тензопреобразователь охвачены сердечниками трансформаторов тока и напр жени .In the proposed device, these disadvantages are eliminated due to the fact that in it the transducers are made in the form of tapes, and one working and one compensating strain gauge are covered by the cores of current transformers and voltage.
Устройство дл измерени усилий представлено на чертеже.A device for measuring forces is shown in the drawing.
Ленточные тензопреобразователи 1-4 зажимаютс в подсоединительных токопровод щих утолшени х 5. Тензопреобразова- тали 2,4 компенсационные и выполнены с изгибом, тензопреобразователи 1,3 - рабочие .Tape strain gauges 1–4 are clamped in connecting conductive thickening bars x 5. Tension converters 2.4 are compensatory and are made with bending, strain gauges 1.3 are working.
Сердечники трансформаторов 6 и 7 напр жени и тока соответственно охватьшают тензопреобразователь 3 и по одному тензопреобразоветелю 2 и 4 соответственно.The cores of the transformers 6 and 7 of the voltage and current respectively cover the strain gauge 3 and each strain gauge 2 and 4, respectively.
К первичной обмотке трансформатора напр жени 6 подключен источник переменного напр жени 8, а ко вторичной обмотке трансформатора тока 7 - измеритель тока 9.A voltage source 8 is connected to the primary winding of the voltage transformer 6, and a current meter 9 is connected to the secondary winding of the current transformer 7.
При отсутсавии измер емых усилий F токи, наводимые в тензопреобразовател х одинаковы, так как равны их сопротивлени . По короткозамкнутым цеп м протекают токи ц и 1-2, равные по величине и создают противоположно направленные магнитные потоки. В результате по измерителю тока 9, включенному на выходе трансформатора 7, ток не протекает.In the absence of measurable forces F, the currents induced in strain gauges are the same, since their resistances are equal. The currents ts and 1-2 flow through short-circuited circuits, which are equal in magnitude and create oppositely directed magnetic fluxes. As a result, current meter 9 connected at the output of the transformer 7 does not leak current.
При раст жении или сжатии устройства под действием усили Р рабочие тензо- преобразователи 1,3 деформируютс , и ихWhen the device is stretched or compressed under the action of forces P, strain gage transducers 1.3 are deformed, and
