METHOD AND DEVICE FOR MONITORING AN OIL LEVEL IN A MACHINE

A method for monitoring an oil level in a machine includes transmitting a light beam into an optical system to be reflected or refracted to a receiver to generate a reception signal. The light beam is emitted at a set transmission power, and an oil deficiency is recognized when the reception signal...

Summary:A method for monitoring an oil level in a machine includes transmitting a light beam into an optical system to be reflected or refracted to a receiver to generate a reception signal. The light beam is emitted at a set transmission power, and an oil deficiency is recognized when the reception signal exceeds a predefined level value. The transmission power of the light beam is settable between a minimum and a maximum transmission power, and contamination of the optical system is analyzed by: (a) the transmitter transmits a first light beam at the maximum transmission power to generate a first reception signal, and (b) analyzing the difference between the first reception signal and a second reception signal generated by a light beam at less than the maximum transmission power, the magnitude of the difference representing a measure of the degree of contamination of the optical system.
