Abstract

Изобретение относитс  к контрольно-измерительной технике. Цель изобретени  - повышение производительности и достоверности контрол - достигаетс  за счет введени  в устройство датчика 2 изменени  тока, усилител  5, компаратора 6, блока 7 индикации. Объект 3 контрол  размещаетс  на стапе вибратора 4. При наличии дефектного па ного соединени  датчиком 2 трансформируетс  изменение тока в цепи питани э затем усиливаетс  усилителем и поступает на вход блока 7 индикации. Вновь введенные блоки обеспечивают высокую производительность за счет интегральной оценки качест а па ных соединений , а также достоверность за счет предварительной калибровки устройства . В устройство включены блок 1 питани , вибратор 4, имитатор 8, 4 ил. с ЈThis invention relates to instrumentation technology. The purpose of the invention — an increase in the performance and reliability of the control — is achieved by introducing a change in current, amplifier 5, comparator 6, and display unit 7 into the sensor 2 device. The control object 3 is placed on the vibrator 4 stack. If there is a defective fuse connection, the sensor 2 transforms the change in current in the power supply circuit e, then is amplified by the amplifier and is fed to the input of the display unit 7. The newly introduced units provide high performance due to the integral assessment of the quality of paired connections, as well as reliability due to preliminary calibration of the device. The device includes a power supply unit 1, a vibrator 4, a simulator 8, 4 or less. with Ј
