AD-MV 500 GL

back to products


The measuring value transformer AD-MV 500 GL transforms the measuring signal emitted from a resistance thermometer (Pt 100) to an impressed output signal (i.e. 4...20 mA, 0...10 V o.a.). The output characteristic is outputted temperature-linear. When using the 3- or 4-conductor switching, the conductor resistances are compensated up to 100 Ohm. With 2-conductor switching, a subsequent zero balance and full balance is necessary. The measuring process can be set via easily accessible DIP switches at the front. The analogue output signal is always galvanic separated from the supply voltage and also from the input. Input and output data must be stated in clear text when ordering. With the input, the temperature measuring range must be stated and with the output, as alternative, current or voltage output can be selected.


Temperature measuring with Pt100 temperature transmitter for continuous transformation of temperature variables to analogue signals.
