Abstract: An apparatus for determining and/or monitoring a physical or chemical process variable of a medium, having a sensor unit, which produces a measurement signal with a piece of process variable-dependent, basic information, and having an evaluation unit which, from the measurement signal of the sensor unit, determines a measured value for the process variable, and which produces an output signal with information concerning whether the measured value is greater or smaller than a limit value. A first and second modulation range are provided, and the evaluation unit modulates the output signal within the first or second modulation range with the basic information of the measurement signal, with the evaluation unit modulating the output signal within the first modulation range when the process variable is smaller than the limit value, and with the evaluation unit modulating the output signal within the second modulation range when the process variable is greater than the limit value.

Abstract: A field device for monitoring and/or determining a process variable of a medium, wherein the process variable preferably is fill level, viscosity or density of the medium. The field device includes: an oscillatable unit; a driving/receiving unit, which excites the oscillatable unit to oscillate, or which receives the oscillations of the oscillatable unit, as the case may be; and a control/evaluation unit, which controls the oscillations of the oscillatable unit, or which evaluates the oscillations of the oscillatable unit. control/evaluation unit produces an accretion alarm, when the oscillation frequency (f) of the oscillations of the oscillatable unit falls below an adjustable limit value (G; GMinimum; GMaximum). The limit value (G; GMinimum; GMaximum) is determinable and/or calculable at least from measured and/or calculated dependencies of the oscillation frequency on process conditions and/or on the process variable to be monitored and/or determined.
