    The serial number on the type label of the instrument allows you to call up the order data, operating instructions manuals, sensor data for the service DTM as well as the test certificate (depending on the instrument). To do this, open under www.vega.com, "VEGA Tools" and "serial number search". Scope of the operating...
  • Page 8: Principle Of Operation

    The running time of the radar pulses from emission to reception is proportional to the distance and hence to the level. The determined level is converted into an appropriate output signal and outputted as measured value. VEGAPULS 62 • Foundation Fieldbus...

    The interface adapter VEGACONNECT enables the connection of communication-capable instruments to the USB interface of a PC. For parameter adjustment of these instruments, an adjustment software such as PACTware with VEGA-DTM is required. You can find further information in the operating instructions "Interface adapter VEGACONNECT" (Document-ID 32628).
