ELECTRONICS

The powerful electronics processes the signals supplied by the flow meter and ensures that processes are precisely monitored, regulated and controlled. It is used, for instance, in process technology as a control unit for dosing and mixing systems or as flexible measuring and recording electronics for differentiated applications in test bench technology for use.

Plug-on display SD 1

The SD 1 plug-on display is a universally applicable local display for all volume counter series (VC, SVC, TM) with Hirschmann plugs. The display can show either flow rate or volume.

Details

    Function

    • The display is inserted between the plug and the plug socket of the volume counter. The display can show either flow rate or volume. For external processing, the same square-wave signals are available as for the standard counters.
    • Previously supplied volume counters can be retrofitted with the plug-on display. To do this, remove the amplifier board in the plug of the existing volume counter.
    • The plug-on display can be freely programmed. All the necessary settings can be made using two keys. The programmed data are stored in an EEPROM so they are retained even in the event of a power failure.
    • As an option, the plug-on display is available with a flow/volume proportional current output (0 – 20 mA, 4 – 20 mA) or with two programmable relay contacts. The square-wave signals are then no longer required.
