<p>The device comprises a converter for converting the actual temperature of metal to a digital pulse code and a clock pulse generator which are connected through their outputs to a synchronization unit. A synchronized clock pulse output of the synchronization unit is connected to a count input of a time interval counter; synchronized code pulse outputs of the synchronization unit are connected to add and subtract inputs of a reversible counter and a threshold counter having overflow outputs connected to reset inputs of the time interval counter. The device also comprises a code selection unit with its inputs connected to digit outputs of the reversible counter which is provided with a count suppression input. The device further includes a flip-flop, a NOT element, and two gates with their inputs connected to the overflow output of the time interval counter, and their outputs connected to set and reset inputs of the flip-flop. An output of the flip-flop is connected to the count suppression input of the reversible counter, and an output of the code selection unit is connected to the control input of the first gate and, through the NOT element, to the control input of the second gate.</p> |
