Description
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.
Specific characteristics
Bipolar voltage/current inputs
Supply of 2-/3-wire transmitter
Potentiometer input
Current and voltage output, differently scalable and can be utilised simultaneously
Error message with missing or defective sensor at measuring range 4-20 mA
LCD for display of different operating modes, lit in several colours (R/Y/B).
Freely definable scaling of the quantity to be measured through stating range, decimal point position and unit from the list or defined unit.
Zoom function, expanded scale, linearizing, inverse mode
Learning Mode Range
Automatic or manual simulation operation
Monitoring of the measuring signal with up to 4 freely adjustable limiting values
Slave pointer function (saving min. and max. value)
