ABSTRACT:
A digital analyzer for determining the liquidus temperature of metals and alloys comprising a converter of the actual temperature of metals and alloys to a digital pulse code which is connected via a synchronization unit to a reversible counter and to a discriminator of local temperature increments. Outputs of the converter are connected to reset inputs of a first time interval discriminator and to reset inputs of a second time interval discriminator. Count inputs of the first and second time interval discriminators are connected via the synchronization unit to a clock pulse generator. An intermediate output of the first time interval discriminator is connected to a disable input of the second time interval discriminator having an intermediate output connected to a control input of a register, an output of the first time interval discriminator and that of the second time interval discriminator being connected via an OR gate to a control input of a digital display unit which is connected via the register to the reversible counter.
