    摘要： A symmetrically wired device and a process for measurement of the concentration of ions, especially hydrogen (H+) ions, in a measurement liquid. The device comprises a pH-sensitive measurement electrode, a reference electrode and a comparison electrode, all located in the measurement liquid and which places the measurement liquid at a definable ground reference. The device forms a difference signal referenced to the ground reference from the difference between a measurement signal (φpH) of the measurement electrode and the reference signal (φref) of the reference electrode. The difference signal is dependent on the ion concentration in the measurement liquid. The device compensates for the noise potential (φchem) arising between the comparison electrode and the measurement electrode by setting a reference potential (φbez) on the comparison electrode, such that φref assumes a zero value.

    摘要： A method for detecting component defects of an analog signal processing circuit, especially for a measurement transmitter. A test signal TS is generated at a first test point TP1 and an associated response signal RS tapped at a second test point TP2 and evaluated in a digital unit. In the evaluation, individual amplitude values of the response signal RS are compared with predetermined, desired values. In the case of significant deviations, a defect report is generated.

    摘要： A design for constructing an input circuit to receive and process an electrical signal, such as a voltage signal from a voltage source, where the input circuit has an extremely high resistance of at least 1011 ohms and is located on a printed circuit board. A first area of the printed circuit board carrying components of the input circuit is separated from a second area surrounding or contiguous to it by a channel-shaped recess to preserve the high resistance of the circuit even under operating conditions and at high relative humidity. The circuit is configured in such a way that the channel-shaped recess terminates in the interior of the printed circuit board and is extended in the direction of the thickness of the printed circuit board immediately up to a moisture-impermeable barrier layer which underlies the first area of the printed circuit board. The channel-shaped recess and the first area are filled and surrounded by a cohesive moisture-impermeable material.

    摘要： The invention relates to a method for registering a measured variable of a measured medium via a measurement path having a sequence of signals, wherein, apart from an original signal of the sequence, each signal of the sequence is a function of a preceding signal of the sequence, at least one signal of the sequence is transformed as a function of the measured variable by interaction with the measured medium, wherein a time variation is impressed on at least a first signal of the sequence, and a second signal, which is present in the sequence of signals at any location after the first signal, is formed by integration of a signal directly preceding the second signal, wherein, additionally, for ascertaining the measured variable, it is assumed, that the measured variable remains essentially constant during the integration.
