ABSTRACT:
A device (1) for determining the qualify of a medium, particularly of a lubricant and/or cutting oil, includes a number of sensors (3, 4, 5, 6, 7) that emit electric output signals according to the respective sensor-specific input variables. One sensor is a temperature sensor (7) that emits an output signal, which is essentially only dependent on the temperature (T) of the medium and is essentially independent of, in particular, the quality of the medium. At least one other sensor (3, 4, 5, 6) emits an output signal that is dependent on both the quality of the medium as well as the temperature (T) of the medium. The sensors (3, 4, 5, 6, 7) are placed on a shared substrate (2) that can be immersed in the medium. An associated process also determines the quality of a medium.
