Definitions
- the invention relates to a device for determining and / or monitoring at least one physical or chemical process variable of a medium with at least one mechanically oscillatable unit, which consists of a tube and an internal oscillator, the tube having an end facing away from the process with a fastening unit is connected, the end of the tube facing the process being formed as a free end, the tube surrounding the inner vibrator, and the inner vibrator having an end facing the process being attached to the end of the tube facing the process, and at least a drive / receiver unit, wherein the drive / receiver unit excites the mechanically oscillatable unit to vibrate, or wherein the drive / receiver unit receives the vibrations of the mechanically oscillatable unit.
- the process variable is, for example, the fill level, the viscosity or the density of a medium.
- the medium can be a liquid or any other bulk material.
- the patent DE 692 02 354 T2 describes a level sensor of the vibrator type.
- a detection tube unit is attached at one end as a fixed end to a fastening unit and is closed at the other end with an end cap.
- An inner vibrating part is attached to this end cap and in the tube unit.
- the vibrating member has an elongated rectangular rod shape.
- a vibrating device is attached to a side surface of this vibrating part.
- the detection tube, the end cap and the inner vibration part together form a folding boom.
- a detection device is mounted in the end cap, which changes the vibration of the
- the aspect ratio should be between the length of the tube and the length of the vibrating part are between 1.6 and 3.0. If the tube unit is fastened to the fastening unit via a membrane, a vibration knot of the folding boom can be moved towards the fastening unit. This makes it possible to use a shorter length of the tube unit. With a membrane, the length ratio between the length of the tube and the length of the vibrating part should be between 1.0 and 2.5.
- a disadvantage of this folding boom is that the length of the sensor is very long. This is because the vibration frequency of the folding boom is determined by the mass and by the length of the inner vibration part. In order to reduce the vibration frequency, the inner vibration part must be as long as possible.
- the object of the invention is to determine and / or monitor a physical or chemical process variable of a medium a mechanically oscillatable unit and a drive / receiver unit, the measurement accuracy being as great as possible.
- the inner oscillator has at least one groove / taper which determines at least the oscillation frequency of the mechanically oscillatable unit.
- the oscillation frequency essentially depends on the moment of inertia of the inner oscillator in relation to the axis of rotation in the groove / taper. Further dependencies result from the bending stiffness of the designated section of the inner vibrator with groove / taper and from the mass moment of inertia of the tube in relation to the axis of rotation in the clamping of the fastening unit.
- the torsional stiffness of the area of the fastening unit to which the tube is fastened is still slightly involved in the oscillation frequency.
- the torsional stiffness for the inner vibrator is defined by the diameter and / or the length of the groove or the taper.
- the mass of the inner vibrator is also affected. This may have to be taken into account in the further design of the inner vibrator. Because the torsional stiffness the vibration frequency can be determined via the
- the working frequency can be set appropriately.
- the vibration frequency can thus be reduced via the dimensioning and / or the position of the groove or the taper, as a result of which the amplitude of the vibration increases.
- the further configuration is also relevant, as already noted above.
- the advantage is that the inner vibrator is designed as a turned part, which is cost-saving.
- the groove or taper is preferably rotationally symmetrical, so that, among other things, no imbalance occurs.
- the internal vibrator due to the groove / taper is still so stable that no deformation or the like can result from the vibration.
- the groove / taper is located in the direction of the end of the inner vibrator facing the process.
- the groove / taper is thus optimally between the transition between the tube and the inner vibrator.
- the inertial mass of the inner vibrator is greatest above the groove / taper.
- this is the point at which the forces act and where the torsional rigidity also affects.
- the positioning of the groove / taper also depends on the position and design of the drive / receiver unit, so that the drive / receiver unit acts optimally or can receive optimally, or that as far as possible no destructive forces and moments act on the inner vibrator ,
- the vibrating parts (tube and inner vibrator) transmit forces and torques from the
- Fastening unit as reaction forces and moments are included.
- the fastening unit or base unit is connected directly or possibly via a further element to the container in which the medium is located.
- the mechanically oscillatable unit is in energetic balance. This means that the sum of the forces and torques generated by the individual components during the oscillatory movement are essentially zero in the fastening unit.
- An advantageous embodiment includes that an additional weight is provided in the fastening unit.
- the mechanically oscillatable unit is essentially decoupled from the fastening unit with regard to the transmission of oscillation energy.
- the weight also has the benefit of making the clamping more stable in terms of vibration.
- Advantageous embodiments provide that the tube and / or the inner vibrator has a round, elliptical, square or polygonal cross section. So there are hardly any specifications or limits for the geometry.
- a round cross section of the tube has the advantage that the risk is reduced that the mechanically oscillatable unit can be bent by the material. It can also be installed anywhere in the medium container. Furthermore, with a round cross section, the production is simple and inexpensive.
- the inner vibrator is hollow, solid or partially hollow and partially solid. It should be ensured that the internal vibrator is stable enough in this area despite the groove or taper, i.e. it must not break off due to the vibrations. Since the mass plays an important role for the inner vibrator, it makes sense to design it as a solid material. With a hollow tube, the oscillation frequency would be increased. Of course, this again gives you the opportunity to set the oscillation frequency.
- An advantageous embodiment includes that only a single piezo unit is provided in the drive / receiver unit, which serves as the drive unit and as the receiver unit.
- Another embodiment includes that at least two piezo units are provided in the drive / receiver unit, at least one piezo unit serving as the drive unit and at least one piezo unit serving as the receiver unit, the piezo units being positioned at the same position. This enables the installation of the piezo unit and the construction of the tube, inner vibrator and other possible fixing elements to be significantly simplified. This also simplifies the wiring of the piezo unit. Further advantages of using only one unit are the lower manufacturing costs. Another advantage is that an assembly that is independent of the transducer is manufactured, which can be checked and tested before installation, which is always desirable in production.
- the piezo units are usually clamped. In the case of such a piezo unit, it is also important for the effectiveness, among other things, that the inner vibrator is connected as far as possible to the entire surface of the piezo units, that is to say, for example, the groove / taper is not seated directly on the piezo unit which has a significantly larger diameter. This and similar
- a very particularly advantageous embodiment includes that the piezo unit is a piezoelectric element that consists of at least two segments that are polarized in opposite directions, the polarization directions being parallel to an axis of rotation of the mechanically oscillatable unit. If a voltage is applied to the top and bottom of this piezo unit, one segment contracts and the other segment expands, i.e. one segment has a lower height, the other a larger height.
- This special piezo unit therefore has the great advantage that direct tilting movements or rotating movements can be generated or detected.
- the drive / receiving unit is positioned between the end of the inner vibrator facing the process and the end of the tube facing the process.
- This positioning in connection with the specially designed piezo unit serves to excite the mechanically oscillatable unit for direct tilting movements or for rotary movements, or for vibrations consisting of such movements to be received.
- Further advantages are that the parts are simple and easy to assemble, that a direct and rigid coupling with the transducer is created, and that axial movements, e.g. Disorders, due to different
- the inner vibrator has at least one second groove / taper.
- the drive / receiver unit is positioned between the first groove / taper and the second groove / taper.
- the first NutA / taper is very close to the end cap, i.e. at the end of the end of the inner vibrator facing the process and also the tube.
- the drive / receiver unit is also located as close to this end as possible, or close to the fixation of the inner vibrator, so that the vibrational energy can be optimally used.
- the piezo unit with the opposite polarizations is very effective. This structure increases the measuring sensitivity of the sensor.
- FIG 3 shows a cross section through a further implementation of the device.
- Fig. 1 shows a cross section through an implementation of the device.
- the mechanically oscillatable unit 1 consists of a tube 2 and an inner oscillator 3.
- the tube 2 has two ends. One is facing the process 6, the other is facing away from the process 4. With the end 4 facing away from the process, the tube 2 is on a fastening unit 5 attached. In the case shown here, the end 4 facing away from the process is fastened in a screw-in piece 10.
- the screw-in piece 10 can also be a membrane in the fastening unit 5.
- the design of the membrane 10 also determines the oscillation frequency of the mechanically oscillatable unit 1. A membrane is present when the diameter of a fastening disk is much larger than its thickness.
- the difference between the outside diameter and inside diameter should be much larger than the thickness of the membrane.
- the oscillation frequency of the mechanically oscillatable unit 1 decreases with decreasing membrane thickness.
- the amplitude of the vibration of the mechanically oscillatable unit 1 also decreases.
- an additional weight 12 is also provided in the fastening unit 5, which on the one hand makes the fastening unit 5 more stable and on the other hand contributes to decoupling the oscillatable unit 1 from the fastening unit 5.
- An end cap 11 is attached to the end 6 of the tube 2 facing the process.
- a bore 17 is provided in the end cap 11, into which the fixing element 18 of the end 7 of the inner vibrator 3 facing the process is introduced in order to connect the inner vibrator 3 to the tube 2.
- Such a screw connection 17, 18 makes it possible, for example, for the inner vibrator 3 to be fixed easily and in a reduced manner even at a very long tube 2 at the end 6 of the tube 2 facing the process.
- a longer tube 2 could be required, for example, for special media or for special containers.
- screwing also makes sense to provide the end 13 of the inner vibrator 3 facing away from the process with a slot, so that, for example, the
- the drive / receiver unit 8 which excites the mechanically oscillatable unit 1 to vibrate or receives the vibrations of the mechanically oscillatable unit 1, is fixed to the tube 2 between the inner oscillator 3 and the end cap 11.
- the drive / receiver unit 8 is designed in this case as a ring.
- at the drive / receiver unit 8 is preferably at least one piezo unit 16. If different piezo units 16 are provided for drive and reception, this plurality of piezo units 16 is also in the same position, for example within a stack. A piezoelectric unit with two opposite polarizations can generate direct tilting vibrations at this position.
- the inner vibrator 3 is a solid round rod. However, other shapes are also possible.
- the oscillator 3 has a groove 9 in the direction of the end 7 facing the process. A taper would also be possible as a realization.
- the NutA / taper 9 is provided here as rotationally symmetrical.
- the diameter and the length of this groove 9 determine the torsional rigidity Q of the section of the inner vibrator 3 in this groove area.
- the resonance frequency of the inner vibrator 3 is in turn determined via this torsional rigidity C ⁇ and the moment of inertia ⁇ j of the inner vibrator 3.
- the dimensioning of the groove 9 thus has a direct effect on the resonance frequency of the inner oscillator 3.
- the oscillation frequency of the mechanically oscillatable unit 1 corresponds to the resonance frequency of the inner oscillator 3 in the coupled state with the tube 2.
- this oscillation frequency is influenced by the moment of inertia of the tube 2 and their bending stiffness. However, this is only slight as long as the resonance frequency of the tube 2 is very much lower than the resonance frequency of the inner oscillator 3. It is thus possible to influence the oscillation frequency of the mechanically oscillatable unit 1 via the groove 9 and / or its position.
- the basic idea of the invention is therefore that the oscillation frequency of the mechanically oscillatable unit 1 can be adjusted by the groove 9. A lower oscillation frequency leads to the same
- This groove / taper thus enables the inner vibrator 3 to be made shorter can.
- Relevant variables with regard to the groove / taper 9 are their design (diameter, length) and their position on the inner vibrator 3.
- FIG. 2 The acting and occurring forces and moments of FIG. 1 are shown in detail in FIG. 2. It can also be seen here that the tube 2 and the inner oscillator 3 oscillate in opposite directions. During the oscillating movement, the oscillating parts 2, 3 transmit forces Fi, Fa and torques Mi and Ma, which are taken up by the fastening unit 5 as reaction forces Fr and moments Mr. In order to avoid coupling to the container and thus loss of energy or a disturbance due to vibrations of the container, it must be ensured that the mechanically oscillatable unit 1 is in energetic equilibrium. This means that the sum of the forces and torques that are generated during the oscillating movement must be zero in the fastening unit 5.
- the drive / receiver unit 8 or in this case the piezo unit 16 with the two segments, the polarization of which is opposite to one another, is located between the two tapers 9 and 19.
- the configuration of the piezo unit 16 leads to a voltage applied to the piezo unit 16 to the fact that the one segment of the piezo unit 16 contracts and that the other segment expands. A tilting movement is thus generated directly via the the vibrations arise.
- the fastening unit 5 is more solid here than in FIG. 1, or the additional weight 12 is part of the fastening unit 5 in this figure.
- the notch 20 in the inner vibrator 3 can also be seen in this figure, via which the inner vibrator 3, for example, with a Screwdriver can be screwed into the end cap 11 of the tube 2.
- This is also an example of the very easy-to-assemble and thus also inexpensive design of the mechanically oscillatable unit 1.
