FIELD: physics. ^ SUBSTANCE: multi-channel method of measuring temperature, with subsequent input of the obtained data into an IBM compatible computer, is based on use of a voltage to frequency converter. A thermocouple thermo-emf conversion circuit is presented, which consists of: an analogue switching unit, analogue signal amplification unit, analogue to digital converter unit, control unit, unit for interfacing with the bus of the computer, base voltage unit. ^ EFFECT: increased accuracy of obtained results. ^ 1 dwg |
