Disclosed is a method for parametering an apparatus for determining and/or monitoring a predeterminable fill level, wherein the apparatus includes a sensor unit and an electronics. The method includes determining an influence interval for a received signal received by the sensor unit as a function of an environmental parameter, determining a first value for the received signal or for a variable derived from the received signal corresponding to a first switch state, determining a second value for the received signal or for a variable derived from the received signal corresponding to a second switch state, and determining a third value for the received signal or for a variable derived from the received signal corresponding to a first switching point based on the first switch state and/or the second switch state and taking into consideration the at least one influence interval.

The present disclosure relates to a method and corresponding sensor for determining density and/or viscosity of a medium using a vibronic sensor. An oscillatable unit is excited using an electrical excitation signal to execute mechanical oscillations, and the mechanical oscillations of the mechanically oscillatable unit are received and transduced into an electrical, received signal. The excitation signal is produced based on the received signal such that at least one predeterminable phase shift is present between the excitation signal and the received signal, wherein a frequency of the excitation signal is determined from the received signal at the predeterminable phase shift. A damping and/or a variable dependent on the damping are/is determined from the received signal at the predeterminable phase shift. From the damping and/or the variable dependent on the damping and from the frequency of the excitation signal, the density and/or the viscosity of the medium are/is ascertained.

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.

An actuating mechanism includes a main body, an electromagnetic device fixed to the main body, and a swinging rod swingably connected to the main body. A position of connection between the swinging rod and the main body is opposite to an iron core of the electromagnetic device, and an upper end of the swinging rod is opposite to and spaced apart from the electromagnetic device. A permanent magnet is disposed on the upper end of the swinging rod, and a magnetic pole direction of the permanent magnet and a magnetic pole direction of the electromagnetic device cross each other. Since the permanent magnet on the swinging rod is opposite to and spaced apart from the electromagnetic device, the swinging rod is not in contact with the electromagnetic device during working process. This avoids knocking of the swinging rod on other components, and therefore prevents noise, reduces wear.

In an example, a fluid level sensor comprises a vibrational paddle wherein an edge of the vibrational paddle comprises a fluid surface contact point having a peaked profile.

The present disclosure relates to a field device of automation technology, comprising a housing and a sensor unit sensitive for a process variable of a medium. The housing has a passageway to accommodate the sensor unit and the sensor unit protrudes from the housing through a terminal opening of the passageway. A clamping angle and a screw are introduced into the housing in a region of the housing adjoining the opening of the passageway. By means of the screw the clamping angle is shiftable in the housing a predeterminable distance in the direction of the sensor unit, and the clamping angle shifted in the direction of the sensor unit is embodied to press with a first clamping angle section of the clamping angle radially on a clamping region of the sensor unit arranged in the housing and facing the opening of the passageway.
