FIELD: measuring equipment engineering, possible use for controlling straining of threaded connections during assembly and operation of machines or equipment. ^ SUBSTANCE: device contains transformer of deformation of resilient element, first and second amplifiers, digital voltmeter with place indicators, commutator, memory block, digital comparator and "NOT" element. Transformer is connected to input of first amplifier, digital voltmeter is connected by input to output of commutator. Input of second amplifier is connected to output of first amplifier, and output is connected to first information input of commutator, connected by second information input to output of first amplifier. Memory block by outputs is connected to appropriate first inputs of digital comparator, by second inputs connected to outputs of appropriate places of digital voltmeter. Output of digital comparator is connected to controlling input of commutator and to input of "NOT" element, by its output connected to holding control input of digital voltmeter indicators. ^ EFFECT: expanded range of measurement. ^ 1 dwg |
