In addition to the type label outside, you canalso find the serial number on the inside of the instrument.3.2 Principle of operationVEGAFLEX 62 is a level sensor with cable or rod probe forcontinuous level measurement.It is designed for industrial use in all areas of processtechnology and can be used equally well in liquids or solids.High frequency microwave pulses are guided along a steelrope or a rod. Upon reaching the product surface, themicrowave pulses are reflected. The running time is evaluatedby the instrument and outputted as distance.Four-wire electronics with separate power supply.The supply voltage range can differ depending on theinstrument version.Data for power supply is specified in chapter "Technical data".Measured value transmission is carried out via the 4 … 20 mA/HART output separate from power supply.The backlight of the indicating and adjustment module ispowered by the sensor. The prerequisite for this is a supplyvoltage at a certain level. The exact voltage specifications arestated in chapter "Technical data".3.3 OperationVEGAFLEX 62 can be adjusted with different adjustmentmedia:l with indicating and adjustment modulel with the suitable VEGA DTM in conjunction with anadjustment software according to the FDT/DTM standard,e.g. PACTware and PCl with manufacturer-specific adjustment programs AMS™ orPDMl With a HART handheldArea of applicationFunctional principleVoltage supplyVEGAFLEX 62 • 4 … 20 mA/HART - four-wire 93 Product description31838-EN-080826
