Guided Microwave Radar Transmitter
FOUNDATION Field Device
The Foundation Fieldbus （FF）protocol based intelligent valve positioner employs two-wire transmission (FF bus signal). Guided Microwave Radar Transmitter is level sensor with a cable or rod probe for continuous measurement. It functions according to the TDR (time domain reflectometry) method. The probe emits high-frequency microwave pulses which are guided along a steel cable or a rod. Upon reaching the surface of the material being measured, a part of the high-frequency pulse can be reflected due to sudden change from dielectric constant. The reflected pulse returns to the unit along with a cable or rod.The distance from material to flange could be figured out by the below formula, after measuring the time-difference between transmitted pulse and reflected pulse.

FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
