Definitions
- the invention relates to the fastening of sensors in an industrial environment.
- the invention relates to a fastening device for a sensor, set up to fasten the sensor to a container, a container with a fastening device attached, a use of such a fastening device, and a method for fastening a sensor to a container.
- Sensors in the industrial environment can be set up for level measurement, point level detection, flow measurement, pressure measurement, level and flow velocity measurement and for temperature measurement.
- Such sensors can be designed for attachment to or in an opening of a container. Fastening takes place either by means of a flange fastening or a screw-in fastening.
- the senor for example a level measuring device or a limit level sensor, has a plate-shaped flange which surrounds the antenna neck of the device in a flange-like manner in order to be screwed to a corresponding mating flange in the area of the opening of the container.
- the antenna neck itself is equipped with an external thread so that the sensor can be screwed into a corresponding internal thread in a container opening via the external thread.
- a first aspect of the present disclosure relates to a fastening device for a sensor, which is designed to fasten the sensor on or in a container.
- the fastening device has a first mechanical interface which is set up to fasten the fastening device to a corresponding first mechanical counter-interface of the container.
- it has a second mechanical interface which is set up to attach the fastening device to a corresponding second mechanical counter-interface of the container.
- the fastening device is set up to accommodate the sensor.
- the receiving device of the sensor can be set up in such a way that the sensor can also be removed again from the fastening device.
- the sensor can, however, also be firmly integrated in the fastening device, movable or immovable.
- first mechanical interface and “second mechanical interface” or, in general, “mechanical interface” are to be interpreted broadly.
- the fastening device can have more than two mechanical interfaces.
- the mechanical interfaces are suitable and set up for the detachable or non-detachable attachment of the fastening device (and thus also of the sensor) to a container wall or a container opening.
- Examples of mechanical interfaces are internal or external threads, flange mountings, ceiling mounts, pipe mounts or brackets. Provision can be made for an adapter flange to be screwed onto the existing thread and thus used. Other fastening options, such as a pipe clamp, can also be mounted on the thread as an add-on.
- the fastening device can be designed in the form of a housing into which the sensor can be inserted or integrated.
- the mechanical interfaces are thus arranged around the sensor, for example.
- the sensor can therefore be located in the middle of the fastening device.

- the fastening device is made in one piece. However, it can also be provided that the individual mechanical interfaces are screwed into the fastening device.
- the base body of the fastening device is cube-shaped or cuboid, with, for example, round recesses in two or more of the side surfaces which have a mechanical counter-interface, such as an internal thread, into which corresponding mechanical interfaces can be screwed.
- the sensor can be designed for process automation in an industrial environment.
- process automation in an industrial environment can be understood as a sub-area of technology that includes all measures for operating machines and systems without human involvement.
- One goal of process automation is to improve the interaction between individual components of a plant, for example in the areas of chemistry, food, pharmaceuticals, petroleum, Automate paper, cement, shipping or mining.
- a large number of sensors can be used for this, which are particularly adapted to the specific requirements of the process industry, such as mechanical stability, insensitivity to contamination, extreme temperatures and extreme pressures. Measured values from these sensors are usually transmitted to a control room, in which process parameters such as level, limit level, flow rate, pressure or density can be monitored and settings for the entire plant can be changed manually or automatically.
- a sub-area of process automation in the industrial environment relates to logistics automation.
- processes within a building or within a single logistics system are automated in the field of logistics automation.
- Typical applications are, for example, systems for logistics automation in the area of baggage and freight handling at airports, in the area of traffic monitoring (toll systems), in trade, parcel distribution or in the area of building security (access control).

- the fastening device has a sensor arranged therein.
- the senor is a level measuring device, for example a level radar device, a limit level sensor, a pressure sensor or a flow sensor.
- Another aspect of the present disclosure relates to the use of a fastening device described above and below for fastening a Sensor either on a side wall of a container or on the top of the container. In both cases, after the sensor has been attached and aligned, the sensor points downwards in the direction of the medium to be measured or in a different "measuring direction".
