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.Power supply via the Profibus DP/PA segment coupler orVEGALOG 571 EP cards. A two-wire cable according toProfibus specification serves as carrier of both power anddigital data signals for multiple sensors. The instrument profileof VEGAFLEX 62 corresponds to profile specification version3.0.The GSD (instrument master files) and bitmap files necessaryfor planning your Profibus-DP-(PA) communication networkare available from the download section on the VEGAhomepage www.vega.com under "Services - Downloads -Software - Profibus". There you can also find the appropriatecertificates. In a PDM environment, an EDD (Electronic DeviceDescription) is also required to enable the full range of sensorfunctions (also available as a download).A CD with theappropriate files can be ordered via e-mail under info@de.vega.com or by phone from one of the VEGA agencies underthe order number "DRIVER.S".The optional heating requires its own power supply.
