摘要： Exemplary embodiments of the present invention include methods and devices for the electromagnetic (inductive) measurement of the conductivity of liquids by immersing a sensor into the liquid, wherein the sensor includes at least 2 toroidal cores, one of said cores carrying an excitation coil and the other core carrying an induction coil. Exemplary methods include converting the induced current at the induction coil into an alternating square-wave voltage, followed by rectification. A sample-hold circuit may be employed to avoid the transition time of the alternating square-wave current conversion. The demodulated DC voltage is proportional to the conductivity of the measured liquid.

摘要： Exemplary embodiments of the present invention are directed to methods and devices for detecting open-circuit and short-circuit failure in an electromagnetic (inductive) measurement of the conductivity of liquids and on the sensor and cable wiring. An electromagnetic measurement of the conductivity of a liquid is performed by immersing a sensor into the liquid, wherein the sensor includes at least 2 toroidal cores, one of them carrying an excitation coil and the other carrying an induction coil. When an AC excitation voltage is applied to the excitation coil, an induced current or voltage can be measured in the induction coil which is proportional to the conductivity of the measured liquid.

摘要： An exemplary method is disclosed which serves to determine a condition of at least one measuring probe which is integrated in a process vessel of a process system with one or more system stages and which is cleaned from time to time using, for example, CIP- and SIP processes, without uninstalling the measuring probe for the cleaning. The temperature of the measuring probe or of the medium surrounding the measuring probe can be measured by a measuring sensor arranged inside or outside the measuring probe, and the condition of the measuring probe can be determined based on a record of the temperature (TS/M) measured over the time when the measuring probe is in operation. In some cases, the method can include monitoring correct execution of the CIP- and SIP processes.

摘要： The measuring device has at least one measuring probe, e.g., a physical or electrochemical measuring probe, which is equipped with one or more memory units and which is connected through a cable, e.g., a coaxial cable, to a transmitter which includes a processor. The measuring probe has a ground wire and is connected to the memory unit through a first signal wire, wherein under the control of the processor in accordance with a transmission protocol, the first signal wire and a connecting cable serve for the unidirectional transmission of the analog or digital measuring signal of the measuring probe as well as the preferably bidirectional transmission between the measuring probe and the transmitter of digital operating data which are read from or to be written into the memory unit.

摘要： A potentiometric measuring probe contains an electrolyte (110) as well as a primary reference element (106) and a secondary reference element (108) that are arranged so that the front (148) of an electrolyte deficiency advancing from an opening (112) of the measuring probe arrives at the secondary reference element before it arrives at the primary reference element. The potential difference existing between the primary reference element and the secondary reference element is monitored, and when a predefined tolerance criterion is found to be violated, the elapsed operating time from the point when the measuring probe was put into operation is determined and used as a basis for calculating the remaining operating time of the measuring probe.
