  • the process variables are, for example, the fill level, the pressure, the viscosity, the temperature, the pH or the density, e.g. a liquid in a container.
  • the Applicant produces and distributes liquid level measuring instruments in which a microwave signal is radiated towards the medium and e.g. from the running time of the reflected signal the level is calculated.
  • Such and many other measuring devices consist at least of the actual measuring sensor, in which, for example, transmitters and receivers are located, and a housing in which e.g. the transmitter and a display or other communication unit are housed.
  • This modular design of the measuring device allows housing and sensor to be replaced separately. However, it is important that the sensor and housing are connected well and securely. There are several points to consider. To ensure easy interchangeability on site, the connection should be as easy to solve.
  • the housing remains rotatable relative to the built-in sensor, so that, for example, the display unit can be aligned so that it is easily accessible to the user.
  • the sensor and the housing are connected to each other via cables and wires. Therefore, the connection should be such that the cables are not or hardly twisted against each other during assembly.
  • the connection should also allow a seal of the interior of sensor and housing against environmental influences and against the medium.
  • a variant is that e.g. the sensor in the
  • the object of the invention is therefore to provide a secure against unintentional release connection between the sensor and the housing, which allows a rotation of the sensor and housing against each other and which is still inexpensive.
  • the invention achieves the object in that the sensor neck or the housing neck has at least one radial groove and at least one axial groove, that the housing neck or the sensor neck has at least one bayonet nose, that the radial groove, the axial groove and the bayonet Nose are configured and matched to one another such that there is at least one latching position, in which the bayonet nose on the axial groove in the radial groove can be introduced, that the sensor neck, the Geeh tungsusehals, the radial groove and the bayonet nose designed and successive are matched, that in the case that the bayonet nose is located in the radial groove, the sensor neck and the housing neck are rotated against each other, that the sensor neck has at least a first retaining element, that the housing neck has at least a second retaining element, and that the first remindhal ⁇ teelement and the second retaining element configured and aufeinande such Are matched so that the first retaining element and the second retaining element in the event that the bayonet
  • the idea of the invention is thus that the housing and the sensor are connected by a kind of bayonet closure.
  • the bayonet nose is inserted into the axial groove ("axial” here in the direction of the longitudinal or symmetrical axis of the sensor neck or of the housing neck) and then into the radial groove ("radial” here is the direction perpendicular to the longitudinal axis , which lies on the radius of the cylinder of the sensor or the housing neck) rotated.
  • the radial groove then allows the sensor and housing to be rotated against each other.
  • the idea can therefore be summarized as follows:
  • the sensor and the housing are connected to each other via a bayonet closure and in the case that both are connected, the relative position of the two parts can no longer be taken, in which the Closure would be reversed.
  • the sensor neck and the housing neck can be configured directly so that via them the connection is possible. Furthermore, the production is easier, which continues to save costs.
  • first retaining element or the second retaining element is a retaining leaf spring.
  • a leaf spring allows in at least one direction an elastic deformation, so that it can be "pushed out of the way” and there is usually at least one direction in which it acts as a rigid obstacle element (usually the direction perpendicular to the direction of elastic deformation). With this configuration, therefore, a simple assembly can be made possible.
  • An embodiment includes that the second retaining element or the first retaining element is a retention nose.
  • a nose or a punch is a simple element, for example, to exert a force on the above leaf spring. Furthermore, such a nose can already be molded on the corresponding component during production.
  • An embodiment provides that the retaining leaf spring and the retaining lug are designed and matched to one another such that the retaining lug in the event that the sensor neck and the housing neck are in the latched position, presses against the retaining leaf spring such that the retaining lug the remindhalte ⁇ leaf spring at least partially elastically deformed.
  • the retaining leaf spring is elastically deformed by the retaining lug and thus pushed out of the way. This is also associated with the fact that the remind ⁇ retaining nose at any other position between the sensor and housing does not elastically deform the leaf spring, but preferably abuts against it and thus prevents rotation of the sensor and the housing to each other in the engaged position.
  • An embodiment provides that the retaining leaf spring and the retaining lug are designed and matched to one another in such a way that, in the event that the bayonet nose is located in the radial groove, the retaining lug at least partially elastically deforms the retaining leaf spring.
  • the retaining lug can therefore not elastically deform the retaining leaf spring in the event that the bayonet nose has been introduced in the radial groove.

  • An embodiment includes that the housing neck or the sensor neck has at least two bayonet lugs, and that the two angles between the two bayonet lugs are different.
  • the number of bayonet lugs increases, so does the number of axial grooves, i. two bayonet lugs are connected with two axial grooves.
  • the advantage that the angles between the noses is different is that there can only be one click position. If the angles were identical, ie 180 ° in each case, then there would be two engagement positions and both relative settings would have to be protected by the retaining elements.

  • Fig. 1 shows the upper portion of the sensor 1 with the sensor neck 2.
  • the sensor 1 is generally cylindrical here. You can see the radial groove 20 and the axial groove 21 (since three bayonet lugs 25 are provided in the housing neck, two axial grooves 21 are also mounted in the sensor neck), which are both connected to each other - ie there is a continuous path through axial 21 and Radial groove 20 - and form part of the bayonet closure.
  • the radial groove 20 is located on the outer side of the cylinder jacket of the sensor neck 2 and completely surrounds the sensor neck 2. The radial groove 20 is thus perpendicular to the symmetry or longitudinal axis of the sensor 1.
  • the axial groove 21 extends along the longitudinal axis of the sensor 1.

  • the position of the axial groove 21 and the first retaining element 31 are matched to one another in such a way that it is possible to introduce the sensor 1 into the housing 11, and subsequently that the unintentional release of the connection is prevented by the retaining elements 31, 32.
  • FIG. 2 shows the housing 11, in which usually the evaluation or processing electronics, the power supply, the transmission units, etc. are accommodated.
  • the sensor neck 2 is inserted into the housing neck 12 and connected to it via the bayonet closure.

  • the sensor 1 and the housing 11 are connected to each other directly by their particular configuration, no additional component is required. This saves material and also production costs.
  • two of three bayonet lugs 25 can be seen here. At least one of the three angles between the three bayonet lugs 25 is preferably different from the other two. In particular, the angles are not 120 ° in each case. This ensures that there is only a single latching position, via which the sensor 1 and the housing 11 are to be connected to each other or to be separated from each other.

  • the sensor neck 2 is plugged into the housing neck 12 here; however, it is obvious that a reverse constellation is equally possible.
  • the fact that both components 1, 11 are connected to one another means that they have first been brought into the latching position relative to one another, and that closing the bayonet nose 25 has been introduced via the axial groove 21 in the radial groove 20 (therefore plug-in rotary connection).
  • the leaf spring 37 is elastically deformed and thus enables the latching position is taken and thereby sensor 1 and housing 11 are connected to each other.
  • the leaf spring 37 is attached here with a screw on the housing 11, so removable if necessary. A rotation of the sensor 1 relative to the housing 11 is possible insofar as the
  • Radialnut 20 encloses the entire cylinder jacket of the sensor 1.
  • the extent of twistability thus depends on how large the radial groove 20 is dimensioned.
  • the retaining lug 36 and the retaining leaf spring 37 prevent the sensor 1 and the housing 11 from being rotated into the latching position in that the retaining lug 36 abuts against the retaining leaf spring 37 and blocks further rotation.
