Definitions
- the invention relates to a device for detecting the fill level of a container, a device for filling containers and a method for detecting the fill level of a container.
- electrically conductive liquids known.
- An elongated electrode is immersed in the liquid.
- the resistance of the electrode itself should be small compared to the contact resistance from the electrode to the liquid.
- a voltage is applied to the electrode at two ends. Due to the different potentials along the electrode, which are in contact with the liquid, stray currents form in the liquid.
- the potential of the liquid outside the range of the stray currents corresponds to the potential of the center of the part of the electrode immersed in the liquid if the stray currents run exactly symmetrically to the center of the immersed part of the electrode. To capture the potential outside the range of
- the stray currents of the immersed electrode are wide
- the object of the present invention is to provide a device and a method for detecting the fill level of a container and a device for filling containers
- Claim 1 an apparatus according to claim 10 and a method according to claim 11. Preferred embodiments are disclosed in the dependent claims.
- a measuring probe is provided which can be inserted into a container and one of which is electrical at two locations
- Resistance path is a linear measurement method for
- Liquid can be detected, however, is integrated in the measuring probe itself. It has been found that even with such an arrangement, in which the
- Resistance path is arranged, meaningful Level measurements are possible.
- An electrically conductive container wall is then no longer necessary, so that glass or plastic bottles can also be used as possible containers.
- Resistance path must be insulated electrically
- An arrangement in which the reference potential electrode is arranged at the lower end of the measuring probe is particularly advantageous. In this area, the stray currents through the resistance section in the liquid are relatively low, so that good linearity is achieved in the measurement.
- the resistance path is advantageously designed as a piece of pipe. This allows an inexpensive and simple construction of the resistance path. Furthermore, this design of the resistance path allows electrical lines to, for example, the resistance path or the
- the lower end of the tube is closed with an insulating piece and / or the reference potential electrode.
- Corresponding seals can advantageously be provided here in order to seal the various parts against one another.
- Lines are contacted to the resistance path, wherein two lines are used to apply a DC or AC voltage to the resistance path and the third line is used to tap a potential.
- Such an arrangement largely eliminates disruptive influences from scattered radiation from the outside, etc.
- a device for filling containers, a device is particularly advantageous which has a device for detecting the
- a measuring probe is first inserted into one
- the reference potential is determined by a reference potential electrode, which is immersed in the filling material and arranged on the measuring probe.
- Measuring probe with the resistance path is a simple one
- Figure 1 is a schematic sectional drawing
- Figure 2 is a schematic representation of the measuring probe
- a measuring probe 1 is shown, which is arranged at the end of a rod 2.
- the rod 2 can be conductive or be non-conductive.
- a piece of pipe 3 is attached, which is to be electrically conductive and whose resistance should be relatively low compared to the contact resistance to the liquid.
- the pipe 2 and the pipe section 3 can also be formed in one piece from a pipe, the pipe section 3 then being defined by the contact 12 (see below).
- the pipe section 3 is contacted at the top with a contact 12 and at the bottom with a contact 13.
- Contact 12 has a conductor 8 attached and contact 13 has two conductors 9 and 10. Instead of two conductors 9 and 10, however, only a single conductor can be provided. This means that either the conductor 9 or the conductor 10 is omitted.
- the insulating piece 4 here has a length in the direction along the measuring probe, which is between 1/50 and half the length of the tube piece 3. A length in the range between 1/5 and 1/10 of the length of the pipe section 3 is preferred.
- a reference potential electrode 5 is provided at the lower end of the measuring probe 1, which is formed from a conductive material.
- Reference potential electrode 5 is connected to a conductor 11 at a contact 14.
- the different parts 2, 3, 4 and 5 can, for. B. be connected to adjacent parts by means of screw connection.
- the seals 6, 7 are by the
- Reference potential electrode 5 are detected. For this purpose, for example, the voltage difference between line 10 and 11 or, if line 10 is missing, between line 9 and 11 or between line 8 and 11 can be determined.
- FIG. 2 An application example is shown in Figure 2.
- the measuring probe 1 is immersed in a bottle 15 which is filled with a liquid 16.
- the pipe section 3 is here
- the reference potential electrode 5 is also immersed in the liquid, since it is below the lower end of the
- Resistance path 3 is arranged.
- FIG. 2 does not show a filling valve or a filling tube with which the liquid 16 is introduced into the bottle 15.
- the filling tube can be arranged approximately next to or concentrically with the probe.
- the measuring probe 1 is inserted into the bottle 15. At the same time or before, the filling process
- Reference potential electrode 5 and then contacted the lower end of the resistance path 3. In this state, the reference potential electrode 5 has the same potential as the lower end of the resistance path 3.
- the potential of the liquid 16 will change in the direction of the potential as specified by the contact 12 (see FIG. 1).
- This changing potential of the liquid can be detected with the reference potential electrode 5.
- the filling is stopped.
- the measuring probe is then removed from the container 15.
- Such a bottle filling can, for. B. in one
