LOW POWER RADAR LEVEL INSTRUMENT WITH ENHANCED DIAGNOSTICS |
摘要 |
A low power radar level instrument with enhanced diagnostics is disclosed. A microwave transceiver generates a microwave signal that travels along a termination, through a reference impedance discontinuity, and into a process product interface. A first portion of the signal is reflected by the reference impedance discontinuity, and a second portion is reflected by a process product interface. A diagnostic signal is provided based upon a characteristic of the first reflected portion. A level output is provided based upon the first and second reflected portions.
