Abstract
Disclosed is an apparatus for determining and/or monitoring a predetermined fill level of a medium in a containment. The apparatus includes a sensor unit and an electronics unit. The electronics unit includes a limiting unit embodied to limit an electrical current or voltage in at least one portion of the electronics unit, a switching unit embodied to control a process switch, and a signal transformation unit embodied to transform a dynamic, electrical input signal into a static, electrical output signal. The static output signal flows through at least one component of the electronics unit. Furthermore, the electronics unit is embodied to supply the sensor unit with an excitation signal, to receive from the sensor unit a received signal, to determine and/or to monitor whether the predetermined fill level has been reached, and to produce a control signal.
