Multifunction Transducer

back to products


The digital multi-function measuring transformers of series VarioCheck AD-VC 3 are freely programmable digital measuring transducers with two analogue outputs and up to 4 limiting value relays. Extensive standard equipment and additional options solve almost all imaginable tasks of a modern evaluation. Enter all characteristics directly on the device or use the configuration software „AD-Studio“. VarioCheck AD-VC 3 fulfils all tasks of a universal and secure measuring value recording through integral function modules such as limiting value messages, freely adjustable hysteresis, selectable relay functions, time-delayed switching, automatic or manual simulation modus, free linearizing curves and a wide range of supply voltage.
