METHOD OF OPERATING A FLUID LEVEL THRESHOLD SENSOR

A method for operating a limit sensor, in which the limit sensor is excited for determining a resonance frequency of a vibration system, the vibration system is excited in a frequency range between a lower frequency limit and an upper frequency limit, and a frequency response is subsequently detecte...

Zusammenfassung:A method for operating a limit sensor, in which the limit sensor is excited for determining a resonance frequency of a vibration system, the vibration system is excited in a frequency range between a lower frequency limit and an upper frequency limit, and a frequency response is subsequently detected, with the frequency range being divided into a plurality of sections, and in case of an unknown resonance frequency the vibration system is excited sequentially respectively in successive sections, and the frequency response after each section is detected, and in case of a known resonance frequency the vibration system is only excited in the section in which the resonance frequency is found, and then the frequency response is detected.
