<p>The measurement converter in two, three or four lead technology comprises a constant current source (K) connected to an adaptor unit (A), which feeds the input signals to a measurement amplifier (MV). The amplifier also receives power from an AC/DC mains converter (NG) with the negative lead connected direct to the amplifier and the positive through a receiver (EG). The conversion unit is suitable for rack monting in a standard 19" assembly, with one group of terminals (10-15) for the power supply and instruments and another group (16-21) for the measured value signals and return signals for the control operations.</p> |
