[0061] FIG. 1A, 1B: a first embodiment of the measuring system according to the present disclosure;

[0062] FIG. 2: a second embodiment of the measuring system according to the present disclosure; and

[0063] FIG. 3A, 3B: a further embodiment of the method according to the present disclosure.

DETAILED DESCRIPTION

[0064] FIG. 1 shows a first embodiment of the measuring system according to the present disclosure, comprising two electrochemical sensors 1a, 1b, in this instance two pH probes. The two sensors 1a, 1b respectively have a sensor element SE which serves to detect a measurement signal (explained here and hereinafter only on the first sensor 1a). The measurement signal depends on the pH value of a process medium with which the sensor element SE is in contact in a measuring operation. Furthermore, the sensors 1a, 1b comprise a second inductive interface Sm via which the electrical power required for detecting the measurement signal can be transmitted to the sensor element SE. Data can be transmitted (see aforementioned Memosens interface) in both directions between the sensor element SE and a second data processing unit CS, for example a microcontroller of the sensor 1a; 1b. The signal generated by the sensor 1a; 1b (for example in a Memosens protocol) is then forwarded to a respective sensor connection element 2a; 2b.

[0065] The sensor connection element 2a; 2b has a first data processing unit CA and a first inductive interface Am. The data which the data processing unit CA processes are, for example, measured values and calculations thereof, for instance averages, smoothing etc., or conversions into another data format or adaptations to a specific communication system, such as a specific field bus.

[0066] The sensor connection element 2a; 2b further comprises a connection element display unit 3a; 3b. The connection element display unit 3a; 3b in this instance is one or more LEDs, preferably multi-colored.

[0067] The sensor connection element 2a; 2b is respectively connected to a superordinate control unit 5 with a cable, whereby a wired communication connection 4a, 4b with the superordinate control unit 5 exists. In this instance, the superordinate control unit 5 is a computer and the communication connection 4a, 4b is respectively a USB cable.

[0068] In the event that the sensor connection element 2a; 2b is not self-sufficient in terms of energy, power is supplied to the sensor connection element 2a; 2b by means of said communication connection 4a, 4b or via a further cable, so that the power supply of the sensor connection element 2a; 2b or of the sensor 1a; 1b is always ensured. For this purpose, the sensor connection element 2a; 2b can be connected to a wired power source, for example a USB charger, so that a continuous supply of power to the sensor connection element 2a; 2b via the power network results.

[0069] A guided menu 10 of a computer program product, in which measured values and/or steps of a calibration or instruction are displayed within the context of a measurement mode or calibration mode, is displayed at a superordinate display/input unit 6, in this instance a screen with a keyboard connected to the computer. This solution is distributed by the applicant under the name, Memobase Plus.

[0070] According to the present disclosure, a display signal AA that is displayed by means of the LEDs of the connection element 3a; 3b is adapted to a display signal Asup displayed at the superordinate display/input unit 6. In the event of multicolor LEDs, a first LED can be interpreted as a channel assignment, in such a way that to which sensor 1a, 1b the display signal Asup displayed at the superordinate display/input unit 6 relates can be perceived directly at the connection element 2a, 2b.

[0071] A second LED can, for example, be reserved for a measurement view in which a sensor 1a; 1b that is used for a plurality of samples and/or a plurality of process variables can be assigned to a respective sample measurement. For example, for a specific sample the pH value and the conductivity value are determined simultaneously with two sensors 1a, 1b.

[0072] In addition to this channel assignment that is thus enabled, the LEDs can also be used to display a needed action, for example in the context of a calibration (Now immerse the first sensor la in buffer 7.00 pH) according to a specification on the screen. This is achieved by a specific LED flashing, for example.

[0073] Alternatively or additionally, the connection element display unit 3c (see FIG. 1B), for example a further sensor 1c, can be designed as a segment display, a display, or a rotary wheel with a digit or color sequence.

[0074] A further embodiment of the measuring system with three sensors 1a, 1b, 1c is shown in FIG. 2. The sensor connection element 2c (explained here and hereinafter only in the example of the third sensor 1c, for the sake of simplicity) here comprises an energy store 7 and two wireless modules 81, 82. The connection element display unit 3c is in this instance a display, wherein all the variants of the connection element display unit 3c (LEDs, segment display, rotary wheel with a digit or color sequence) that have already been shown in conjunction with FIGS. 1A, 1B are of course also possible, and are not explicitly shown here again.

[0075] In this instance, the sensor connection element 2c is respectively arranged close to the sensor and is connected to the sensor 1c by means of two mutually compatible interfaces Am, Sm. Power is transmitted to the sensor 1c by means of the energy store 7. The sensor connection element 2c can thus be regarded as energy-independent. The energy store 15 is designed as a preferably chargeable battery, for example a lithium ion accumulator. The energy store 15 is preferably charged wirelessly, for example by means of the Qi charging technology. Alternatively or additionally, energy store 15 can be charged by means of a solar cell.

[0076] The sensor connection element 2c comprises wireless modules 81, 82 for the transmission and reception of data at the superordinate control unit 5 by radio connection. This takes place here with a mobile terminal 9 which can be connected to a communication network, for example WLAN, by means of which a communication connection 4c can be established between the sensor connection element 2c and the superordinate control unit 5. The mobile terminal 9 is a smartphone or tablet, for instance, but can also be designed as a computer, and comprises the superordinate display/input unit 6. The data may be measurement data of the sensor 1c. However, the data may also be configuration values (parameters) of the sensor 1c. The sensor 1c is thereby parameterized via the mobile terminal 9, and the parameterization is transmitted by means of the interfaces Am, Sm to the sensor connection element 2c and then to the sensor 1c.

[0077] The mobile terminal 9 has a corresponding interface or transmitting/receiving module. Data transmitted and received by the first or second wireless module 81, 82 are, for instance, the already addressed measured values, calculations thereof, or conversions thereof. Furthermore, firmware updates, changes to settings of the sensor 1a, 1b or of the sensor connection element 2c, or meta-information, such as location information or the measurement site name etc. are also transmitted via the wireless module 81, 82.

[0078] Of course, a measuring system using a combination of the embodiments shown in FIG. 1A and FIG. 2 is also possible. For example, the measuring system may use a first one of the sensor connection elements 2a; 2b; 2c as shown in FIG. 1A, and may further use a second one of the sensor connection elements 2a; 2b; 2c as shown in FIG. 2.

[0079] As already shown in FIG. 1B, the connection element display unit 3a, 3b, 3b is a multicolor display (OLED, . . . ) at which the sample measurement assignments and/or measurement channel assignments can be represented by means of color and/or text.

[0080] Thus, it is immediately recognizable to a user 11 to which sensor 1a, 1b, 1c a measurement displayed at the display/input unit 6 of the mobile terminal 9 belongs, even if the sensors 1a, 1b, 1c are all of the same species. In addition, it can be immediately discerned at the sensor 1a, 1b, 1c whether there is any need to take action, e.g. in which sample or calibration buffer the sensors 1a, 1b, 1c are to be immersed at a point in time specified by a computer program product, or whether a cleaning step is required (action required).

[0081] This is shown in FIG. 3A, 3B. A respective color is associated with each of the sensor connection elements 2a, 2b, 2c, 2d, wherein FIG. 3A shows a calibration mode and FIG. 3B shows a measurement mode. The color on the display 3a, 3b, 3c, 3d of the sensor connection elements 2a, 2b, 2c, 2d is matched to the color of a display signal Asup which is displayed at the superordinate display unit 6, and relates to a respective sensor 1a; 1b; 1c; 1d.

[0082] The user 11 thereby immediately knows on which of the sensors 1a; 1b; 1c; 1d he must concentrate, for example within the context of a calibration, FIG. 3A. Because multiple sensors 1a, 1b, 1c 1d can be calibrated simultaneously, it is thereby clear to which of the sensors 1a, 1b, 1c, 1d an instruction relates, for example Immerse sensor 2b in a container 12a with buffer pH 4.

[0083] FIG. 3B shows how a specific color is additionally used in a measurement mode for a specific sample, for example in a fermenter 12b. In the measuring mode, this is selected at the same time as the color on the display 3a, 3b of the sensor connection elements 2a, 2b, and as the color of a display signal Asup at the superordinate display/input unit 6. For example, each fermenter is assigned a specific color.

[0084] In addition or as an alternative to the matching of the color, text can also be displayed at the display 3a, 3b, 3c, 3d which is matched to the text in the guided menu 10 of the computer program product.
