An inductive proximity switch with a housing formed of a nonmagnetic, high-grade steel, with a transmitting coil, two receiving coils which are connected in series in opposite directions and which are located symmetrically relative to the transmitting coil, and an evaluation circuit which is connected to the receiving coils. At a given size, the inductive proximity switch has a relatively large operating distance and the operating distance is largely stable, especially is largely independent of temperature, essentially in that, on the back of the receiving coils, opposite the influence side, there is a pre-damping element and the pre-damping properties of the pre-damping element at least approximately correspond to the pre-damping properties of the housing on the influence side.

Inductive proximity switch

A mounting device for contactlessly-operating proximity switches includes a continuous cylindrical or cuboidal recess for holding the proximity switch which is formed by at least two legs. The mounting device can also include at least one through pocket, connected to the recess, into which an actuating tool can fit. The recess of the mounting device, when in a relieved state, has a smaller diameter than the proximity switch which is to be mounted. Additionally, the recess can be spread into an enlarged state by the actuating tool being positioned into the pocket and turned.

Mounting device for sensors

A capacitive fill level measurement device with a fill level sensor having a plurality of sensor fields, electrical wires for electrically connecting the plurality of sensor fields to a multipole side of a selector switch, and a power supply and evaluation circuit electrically connected to a monopole side of the selector switch. The capacitive fill level measurement device can be made with simple production technology and thus economically for a host of different applications using a matrix of printed conductors which extend vertically and horizontally such that each horizontally extending printed conductor on one side is connected to one sensor field and on the other side connected to a vertically extending printed conductor. Each horizontally extending printed conductor is connected with a respective vertically extending printed conductor to form an electrical line or a part of an electrical line.
