Definitions
- the present invention relates to a measuring device with an elongated first electrode for insertion into a material to be measured and a sheath at least partially surrounding the first electrode.
- Such measuring devices are used, for example, to measure the pH of foods, e.g. of meat.
- a chamber is usually formed between the first electrode and the casing, in which a second electrode, for example made of a gel, is accommodated. Both electrodes are connected to an evaluation circuit for determining the pH value of a liquid of the sample which has penetrated between the electrodes.
- the measuring device with the first electrode is driven into the material to be measured with great force, which leads to a considerable mechanical load on the first electrode.
- the first electrodes for pH measurement are usually made of glass or have glass as a sheathing and can be heavily loaded in the axial direction, that is, the direction of insertion. Vertical to the axial direction, these first electrodes can only be subjected to a small load due to the brittleness of glass, which can lead to breakage when loaded in this direction, for example when the measuring device is tilted when piercing or pulling out.
- measuring devices are offered in which the glass electrode or the gel surrounding the glass electrode is surrounded by a glass jacket and then by a metal or plastic sleeve. This increases the resilience of the glass electrode perpendicular to
- the double cladding made of glass and plastic also results in a larger diameter in the area of
- Probe tip which causes larger holes in the material to be measured.
- the object of the present invention is to provide a measuring device with a first electrode which is more robust with respect to loads perpendicular to the axial direction.
- the elongated first electrode of the measuring device is pivotally mounted and can thus avoid this load to a certain degree perpendicular to the axis of the load, whereby a breakage of the first electrode, which is preferably designed as a glass electrode, can be avoided.
- the sheathing In order to enable the first electrode to pivot under lateral load, it is necessary that the sheath also follows a pivoting movement of the first electrode in a direction perpendicular to the electrode axis.
- the sheathing preferably consists of a flexible, or non-brittle, material, for example a flexible plastic.
- the bending behavior of the sheathing is improved in accordance with one embodiment of the invention in that the diameter of the sheathing increases in the area of the receiving device or in the area of a "fictitious hinge point" of the glass electrode.
- the fictitious hinge point is a point of the first electrode around which it is caused by the articulated mounting is pivotable on the recording device, which does not change its position when the first electrode is pivoted.
- no glass sheathing around the gel forming the second electrode is required for stabilization.
- the pivotable mounting of the first electrode is preferably carried out by means of a receiving device receiving the first electrode at one end.
- the receiving device preferably has a recess which receives the first electrode, a bottom region of the recess forming a support for an axial end of the first electrode.
- an annular element surrounding the first electrode is arranged between the first electrode and a side surface of the recess for lateral mounting of the first electrode.
- the ring-shaped element which preferably consists of a flexible material, for example an elastomer, in particular silicone, supports the glass electrode at its end introduced into the recess against the side surfaces of the recess in order to hold the first electrode in one position when there is no lateral load To keep the rest position substantially parallel to the side surfaces of the recess.
- the flexible annular element enables the first electrode to pivot laterally in order to prevent the first electrode from breaking.
- the annular element is designed with an essentially circular cross section in the manner of an O-ring, which surrounds the first electrode in the region of the opening of the recess and supports it against the side surface.
- An air gap is formed underneath the ring between the first electrode and the side surface of the recess, which allows sideways movements of the end of the glass electrode.
- the annular element is essentially sleeve-shaped and partially or completely surrounds the first electrode at the end section introduced into the recess. A pivoting movement of the first electrode is made possible by elastic deformation of the sleeve when subjected to a load perpendicular to the axis.
- a recess with an essentially frustoconical shape is provided, a lower end of the recess having the smallest diameter and forming a support for an axial end of the first electrode.
- Lateral support of the first electrode in the recess is not provided in this embodiment. Due to the conical shape of the receptacle, the first electrode is "centered" in the initial length after the transverse load has been removed. The lateral stability is essentially taken over by the sheathing that surrounds the first electrode at least at one point. Lateral pivoting movements of the first electrode at the end introduced into the recess are made possible by the diameter of the recess increasing upwards.
- the first electrode is supported by means of a ball joint, the first electrode preferably being glued into a receptacle in one of the two joint halves.
- the first electrode in a receptacle of a flexible shaft, preferably by gluing.

- Figure 8 Detail of a measuring device according to the invention during the measuring operation when subjected to side forces.
- Figure 1 shows a section of a measuring device according to the invention in a lateral cross-sectional view.
- the measuring device has an elongated, essentially cylindrical first electrode 2 and a sheath 4 which at least partially surrounds the first electrode 2.
- the first electrode 2 is preferably made of glass or has a jacket made of glass and serves as the electrode of the measuring device when determining the pH in a material to be measured.
- a chamber is formed between the first electrode 2 and the casing 4, in which a second electrode 3, preferably in the form of a gel, is arranged.
- the measuring device is introduced in the front area into the material to be measured, usually a food, as this is shown by way of example in FIG. 8, with liquid of the material to be measured in the area between by means of suitable measures not shown here, for example a diaphragm the first electrode 2 and the second electrode 3 arrives.
- the first electrode 2 has a piercing tip at a front end.
- a section of the measuring device contains processing and display devices which are not explained in more detail here and which are therefore not shown. Both electrodes 2, 3 are electrically connected to the processing device for determining and displaying the measured value.
- the first electrode 2 is pivotably mounted.
- a holding device 6 is provided in the area of an end 10 of the first electrode 2 facing away from the piercing tip.
- the sheathing 4 consists of a flexible material that allows the first electrode 2 to pivot.
- FIG. 2 A detailed representation of the receiving device according to FIG. 1 is shown in FIG. 2.
- Piercing electrodes made of glass can be loaded well in the axial direction, but break easily with transverse loads, i.e. with loads perpendicular to the axial direction. Due to the pivotable mounting by means of the receiving device 6 at the end 12 and the flexible sheathing 4, the first electrode 2 can avoid these transverse loads in the event of transverse loads, for example by “tilting” the measuring device when it is introduced into the measured material or when it is pulled out of the measured material.
- the pivotable mounting does not increase the lateral stability of the first electrode 2, but only allows the measuring device according to the invention to pivot it in the event of transverse loads.
- the receiving device 6 has a cutout 8 in which the end section of the first electrode 2 is received, a bottom region 16 of the cutout 8 forming a support for the axial end 12 of the first electrode 2 in order to support the probe against axial forces F.
- the bottom 16 of the cutout 8 has an opening 18 for the passage of connecting lines, the diameter of the opening 18 being smaller than the diameter of the probe 2.
- the connecting line can also be supplied to the first electrode 2 in a groove on the side of the recess or in another suitable manner.
- the first electrode 2 is in accordance with the exemplary embodiment
- FIG. 2 by means of an annular element 12A, which is designed in the manner of an O-ring, against the side surface 14 of the Recess 8 supported.
- the ring 12 preferably consists of an elastomer, for example silicone, NBR, etc.
- the ring 12A supports the first electrode in the region just below the opening of the recess 8. Below the ring 12A, an air gap is formed between the first electrode 2 and the side surface 14, which, when the probe 2 is loaded transversely, allows the end 10 of the probe 2 located below the ring 12A to move sideways, as shown in FIG. 2b.
- the probe 2 pivots about a fictitious pivot point 20, which in the example shown is a point on the axis of the first electrode 2, which maintains its position when the first electrode 2 is pivoted.
- a fictitious pivot point 20 which in the example shown is a point on the axis of the first electrode 2, which maintains its position when the first electrode 2 is pivoted.
- the elasticity of the ring 12A and the elasticity of the sheathing 4 are preferably matched to one another in such a way that the first electrode 2 cannot be pivoted as far as the edge of the recess 8 in order to avoid the risk of breakage, and that the pivoting range of the first electrode is exclusively or at least largely determined by the design the casing 4 is determined.
- the first electrode 2 is firmly enclosed by the casing 4 at at least one point 22 of the casing 4, as a result of which the casing 4 guides the first electrode 2 and contributes to its pivotable mounting.
- the casing 4 is preferably made of a flexible material, for example plastic.
- a fictitious hinge point of the casing 4 coincides with the fictitious hinge point 20 of the first electrode 2.
- the hinge point of the casing 4 can be determined by its geometry. In the embodiment shown in FIG. 1, it is provided that the inside and outside diameter of the casing 4 increase in the area of the receiving device 6 or in the area of the fictitious hinge point 20 of the first electrode 2.
- the casing 4 is preferably frustoconical in this area.
- FIG. 3 shows a further exemplary embodiment of a receiving device 6 for the pivotable mounting of the first electrode 2.
- the receiving device 6 has a cutout 8 in which an end section of the probe 2 is received, the bottom 16 of the cutout 8 being a support for supporting it Forms axial forces F.
- an annular element 12B which surrounds the probe 2 in the region of the end section and is designed in the manner of a sleeve, is provided, which is introduced between the probe 2 and the side surface 14 of the cutout 8.
- the sleeve 12B is formed from a flexible material, preferably an elastomer, and is elastically deformed when the first electrode 2 is loaded transversely, in order to enable the first electrode 2 to pivot, as shown in FIG. 3b.
- the elasticity of the sheathing 4, which is essential for pivoting the first electrode 2, is matched to the transverse load capacity of the first electrode 2. So in the name of good manageability, the sheathing 4 should not be so elastic that the probe 2 dodges to the side even at low transverse loads, at which there is still no risk of the probe 2 breaking, making it difficult to introduce it into the material to be measured.
- FIG. 4 A further embodiment of a receiving device 6 is shown in FIG. 4.
- the receiving device 6a has a frustoconical recess 24, the lower end of which, having the smallest diameter, forms a support for the probe 2 against axial forces F.
- a lateral support of the probe 2 by the receiving device 6a is not provided in this embodiment. Due to the conical shape of the recess 24, the first electrode is removed when the
- the lateral stability in this embodiment is due to the casing 4 ensures that the probe 2 at the point 22 as shown in Figure 1.
- the sheathing 4, which holds the first electrode, is part of the storage of the piercing electrode.
- the smallest diameter of the recess 24 at the bottom of the recess 24 is preferably equal to or slightly larger than the diameter of the first electrode 2 in order to prevent the probe 2 from slipping on the bottom of the recess 24.
- the recess 24 can have different geometrical configurations than that of a truncated cone, in particular that of a cylinder, as shown in FIGS. 2 and 3, where appropriate measures must be taken to prevent the axial end of the probe from slipping at the bottom of the recess.
- the lateral stability can also be ensured in these cases by dispensing with annular elements through the casing 4.
- FIG. 5 shows a measuring device according to the invention in cross section, in which the pivotable mounting of the first electrode is ensured almost exclusively by the sheathing 4, the first electrode being introduced in a very flat recess 26 at the end facing away from the tip without further holding measures, which ensures that this one end of the first electrode is positioned in the middle of the measuring device.
- the first electrode 2 is tightly enclosed by the sheathing in the area of the tip, an elastomer seal 30 preferably being arranged between the first electrode 2 and the sheathing 4.
- the seal 30 abutting the first electrode 2 allows the first electrode 2 to be displaced relative to the seal 30 in order to enable the length of the casing to be compensated for when the first electrode 2 is pivoted.
- FIG. 6 shows a further receiving device 6b as part of a device for the pivotable mounting of the first electrical rode 2.
- the receiving device 6b has a ball joint with a first and second joint half 7a, 7b, the first joint half 7a having a recess 26 for receiving the one end of the first electrode 2, into which the end of the first electrode preferably by means of an adhesive 60 is glued.
- FIG. 6 a shows the ball joint in the rest position
- FIG. 6 b shows the ball joint in the pivoted position of the first electrode 2.

- the holding device 6c has a shaft with a holder 28, in which the first electrode is fastened, preferably by means of an adhesive 30.
- the shaft has a region 9 with a smaller diameter, around which the shaft can be pivoted in the event of transverse loads.
- FIG. 8 shows a section of the measuring device according to the invention in a lateral cross-sectional representation during a measuring operation.
- the measuring device is driven with the first electrode 2 and a part of the casing into a measured material 40 and is subject to a transverse load due to lateral forces F, for example in that the measuring device has been driven obliquely into the measured material and an attempt is now being made to pull it straight out, or thereby that the tip of the first electrode 2 evades a fixed obstacle in the material to be measured 40.
- the flexible sheathing 4 follows the pivoting movement of the probe 2, with length compensation being possible at the point 22 of the sheathing at which the probe 2 is enclosed by the fact that the first electrode is supported by the sheathing 4 so as to be slightly displaceable.
- the measuring device according to the invention has only one casing compared to the measuring devices according to the prior art, as a result of which smaller holes remain in the material to be measured after the measurement. LIST OF REFERENCE NUMBERS
