Description
Evaluation Electronics Local Displays (VTGS Ex) for wall mount with analog and frequency output

All measurement results and parameters relevant for the process can be shown directly on the VTGS via the graphic display (that can be illuminated) and changed using the four membrane keys.

3 linearization banks with 20 points each are available to improve the accuracy. They are used to linearize the measurement signal depending on the chosen operating mode (external control, fixed assignment).

In pure 2-conductor operation (4 - 20 mA) the instantaneous value (flow) is dimensionally output on the current loop according to the programming. A programmable digital output and a maximum of two control inputs (see technical data) are available in addition for further processing and control.
