    The invention relates to a measuring device for detecting at least one parameter of a liquid, in particular a cleaning or disinfecting liquid, comprising at least one sensor, at least one device for supplying energy to at least the at least one sensor and at least one device for forwarding data to and / or from the at least one sensor. The invention further relates to a tank for holding a liquid, in particular a cleaning or disinfecting liquid, with a wall delimiting the tank to the outside, wherein the wall has an inside and an outside. Finally, the invention relates to a metering device, in particular for dishwashers or washing machines.
    Measuring devices of the type mentioned are generally known from the prior art. In connection with the measurement of parameters, in particular the conductivity, of a cleaning liquid, they are described, for example, in DE 103 31 401 and in DE 36 20 900.
    Above all, the use in cleaning fluids, such as wash liquors, is associated with special challenges, since such liquids are highly corrosive and partly - depending on where the measuring device is used - a significant pollution load, which can lead to deposits, exhibit. These factors can be detrimental - direct on the functionality of the sensors, - the attachment of the measuring equipment, for example to a tank containing the liquid in question, and - the passage of cables through which the energy and data are transmitted through the wall of a tank such tanks.
    For example, if it is a sensor for detecting the conductivity, with the help of which typically the concentration of a cleaning agent is determined in a cleaning liquid, it comes with conductive conductivity sensors often calcifications and deposits, whereby a too low conductivity is measured. This results in an overdose of the cleaning agent, which aggravates the problem even further, so that the sensors must be replaced in relatively short time intervals.
    As far as the attachment of the measuring devices and the cable bushings are concerned, bores, rivets and the like are generally required for this purpose on the wall of a tank, which are particularly exposed to signs of wear. These can subsequently be used e.g. lead to leakage of cleaning fluid or electrical short circuits.
    The elimination of all these problems requires premature and costly repair measures, which can result in expensive plant shutdowns, especially in commercially used rinsing or washing machines.
    The present invention is therefore based on the object to remedy the above-described, known from the prior art problems.
    This object is achieved by the features of the independent claims 1,10 and 12.
    As regards the measuring device for detecting at least one parameter of a liquid, in particular a cleaning or disinfecting liquid, it is thus provided according to the invention that the measuring device is subdivided into at least one first assembly and a second, second assembly spatially separated from the first assembly, and the two assemblies are in operative connection with each other electromagnetically via at least one induction device.
    The first assembly of the measuring device advantageously comprises the at least one sensor, a part of the at least one device for power supply and a part of the at least one device for forwarding data, and the second module the two remaining parts of the at least one device for power supply and the at least a device for forwarding data.
    The at least one induction device can be technically realized in a simple manner by having at least two coils, wherein one of the two coils of the first assembly and the other of the two coils of the second assembly of the measuring device is included.
    In view of the present invention, it is important that energy and data can be transmitted without contact, for example through the wall of a liquid tank, by means of such an induction device via electromagnetic fields. This completely eliminates the need for cable penetrations or a power supply by batteries.
    In order at the same time to obviate the need for permanent holders for the at least one measuring device, it has proven to be advantageous that the two assemblies of the measuring device each comprise a permanent magnet, wherein the permanent magnets are arranged to each other so that they attract each other. Assigning now the two modules of the measuring device opposite to a wall of a liquid tank, it is ensured by means of the permanent magnets that hold the two modules mutually. In addition, this type of fastening has two further advantages, namely that the measuring device can be arranged at any point and can also be displaced later, and secondly that centering of the two assemblies relative to one another takes place by means of the permanent magnets.
    As already stated in the introduction, the detection of at least one parameter of a liquid poses a particular challenge with regard to the sensors used, which are, for example, a temperature sensor, level sensor, pH sensor, turbidity sensor and / or conductivity sensor can, dar.
    As regards, for example, the detection of conductivity, it has proven to be advantageous to use inductive instead of conductive conductivity sensors, that is to say conductivity sensors which have at least one transmitter coil and one receiver coil.
    The two coils can be integrated in an annular housing, wherein a bore is guided through the ring and the coils integrated therein. The liquid to be measured encloses the ring and is also located in the hole. A sinusoidal AC voltage is applied to the transmitter coil. The result is a current in the liquid that is proportional to the conductivity. This current in turn generates a voltage in the receiver coil. By measuring this voltage, the conductivity is determined. For metrological correction of the conductivity value, a temperature sensor may also be provided.
    Such an inductive measuring method of the conductivity is not or only slightly influenced by deposits of ingredients that are the liquid.
    In order to further increase the protection against corrosion damage and the like, it is provided according to an advantageous embodiment that one of the two, preferably both, assemblies of the measuring device is at least partially disposed in a potting.
    Further, structurally advantageous embodiments of the measuring device can be found in the dependent claims 8 and 9.
    Particular mention should be made of an embodiment in which the first module and the second module of the measuring device have at least one processor-controlled device, preferably at least one microcontroller or microprocessor, and at least one device for data modulation. In this way, it is possible to transmit the energy required for supplying at least the at least one sensor as well as the data sent to the sensor or the data received from the sensor simultaneously by means of a single induction device. For this purpose, the data are modulated onto the carrier frequency for energy transmission or recovered by means of demodulation after transmission between the modules. Advantageously, a carrier frequency of about 10 kHz - 10 MHz is used.
    As stated above, the invention also relates to a tank for receiving a liquid, in particular a cleaning or disinfecting liquid, with a wall delimiting the tank to the outside, wherein the wall has an inside and an outside. It is provided that the tank comprises at least one measuring device according to the invention, wherein the first assembly of the measuring device is arranged on the inside of the wall and the second assembly of the measuring device on the outside of the wall. By inside, that side of the wall is meant, which faces the interior of the tank or comes into contact with the liquid absorbed by the tank. Preferably, the wall in question at least partially, in particular completely, made of stainless steel.
    And finally, protection is also desired for a metering device, in particular for dishwashers or washing machines, wherein the metering device comprises at least one measuring device according to one of claims 1 to 9, wherein depending on signals from the measuring device, a cleaning or disinfecting liquid in different amounts and / or concentration is delivered.
    Advantageously, the dosing device further comprises at least one preparation device for producing a liquid, in particular a cleaning or disinfecting liquid, wherein a means, in particular a cleaning or disinfecting agent, and a rinsing medium for rinsing the agent can be introduced into the preparation device. The agent which can be introduced into the treatment device can be in powder, granule or block form, for example. The flushing medium is, for example, water.
    Furthermore, it has proved to be advantageous that the metering device comprises at least one tank according to the invention, wherein the tank is connected to at least one inlet and a drain for the liquid, and wherein the treatment device is in communication with the tank via the at least one inlet.
    If the measuring device arranged in or on the tank moreover comprises at least one conductivity sensor, then the arrangement of processing device and tank can advantageously be further developed in such a way that the flushing out of the material into the liquid takes place metered. For this purpose, a control or regulating device is provided, which is in communication with the measuring device and the processing device.
    Further features and advantages of the present invention will become apparent from the figures and the following description of the figures. It shows
