摘要
A method for monitoring the operability of a fill level sensor acting as a FMCW radar device in which the frequency of a radar signal to be sent from the fill sensor during measurement of a fill level of a medium is modulated with a set of pre-settable measuring parameters and a measured value of the fill level determined from at least one received signal received during measurement of the fill level. The method enables simple automatic monitoring of the operability of a fill level sensor acting as a FMCW radar device in that, during a test phase, the frequency of the radar signal to be sent is modulated with at least one set of pre-settable test parameters and a test measured value is determined from at least one test received signal received during the test phase, which is evaluated to establish the operability of the fill level sensor.
