摘要： A method for calibrating a thickness gauge, wherein the thickness gauge measures the thickness of a measurement object in a predefinable measuring direction (Z), comprising at least one displacement sensor (1, 2) operating in a contactless or scanning manner, wherein a reference object (3) having a known thickness and shape is moved into at least a partial region of the measurement field of the at least one displacement sensor (1, 2), comprises the following steps with respect to particularly precise and simple calibration. First, at least two independent measurement values are recorded by the at least one displacement sensor (1, 2) in at least two predefinable sites on a first surface of the reference object (3) at predefinable times t
j , or as a function of predefinable positions p
j of the reference object (3) in the measurement field, where j = 1, 2... Then the tilting or spatial position of the reference object in the measurement field is determined based on the measurement values recorded at the times t
j , or as a function of the positions p
j of the reference object (3). Then, a further measurement value is recorded by the at least one displacement sensor (1, 2) at a further site located in the measuring direction (Z) on a second surface disposed opposite the first surface, or on a surface region of the reference object (3) disposed opposite the first surface, in order to determine a thickness value of the reference object (3) in the measuring direction (Z). Then, the thickness value of the reference object (3) is calculated from the measurement values of the at least one displacement sensor (1, 2) at the times t
j or in the positions p
j in the measuring direction (Z). Finally, the difference between the calculated thickness value and the known thickness of the reference object (3) is calculated in order to obtain position and tilt or location-dependent corrective values in the partial region or measurement field, in order to compensate for geometric errors and/or non-linearities of the at least one displacement sensor (1, 2) in the partial region or measurement field during thickness measurement.-

摘要： As regards a measurement structure which is as simple as possible and in order to influence the mixing operation or the transfer of substances to the slightest possible extent, a method for measuring the mixing ratio of a mixture of substances comprising at least two substances (10, 11) is configured in such a manner that the mixture of substances is brought into the measurement range of a capacitive sensor (1) - in particular is moved past the latter or moved through the latter - and the mixing ratio is determined from the change in the capacitance of the sensor (1), which change is caused by the mixture of substances. A corresponding sensor arrangement in which the mixture of substances is guided through a tubular area (2) is specified.

摘要： The invention relates to a contactlessly working eddy current sensor, particularly for detecting essentially flat test objects (1), comprising at least one sensor coil (4), eddy currents (5) being able to be induced in the test object (1). The invention is characterized in that the coil (4), when passing by the test object (1), is aligned in such a manner that the coil axis (2) is oriented essentially parallel to the normal (6) to the surface of the test object (1), and that the test object (1) can be moved past the sensor coil (4) essentially parallel to the coil axis (2) or the sensor coil (4) can be moved past the test object (1). A corresponding method is carried out so that an eddy current can occur only once when the test object or coil is passed by.

摘要： The invention relates to a device and method for detecting the position and velocity of a test object (5) relative to a sensor (1), the sensor (1) and the test object (5) being arranged so they can be displaced relative to one another. The sensor (1) has a measuring coil (2) with at least one, preferably a number of voltage tap(s) (4) and has a target (7), which is placed on the test object (5) while being electromagnetically coupled to the measuring coil (2). An electronic component (6) for adding the voltages tapped on the sensor (1) is assigned to the sensor. The invention is, with regard to a simplest possible design of the sensor, characterized in that for simultaneously measuring position and velocity, the target (7) comprises two parts (8, 10), one part (8) being made of an electrically conductive material and the other part being provided in the form of a magnet (10), and in that an evaluation circuit (11) determines, based on the output signal of the electronic component (6) for adding the tapped voltages, a voltage component Up that is proportional to the position of the target, and a voltage component Uv that is proportional to the velocity of the target.

摘要： The invention relates to a method and to a device for measuring speed in a contactless manner, comprising a proximity sensor (3) which operates according to the eddy current principle. The proximity sensor (3) comprises an inductor (4) and a parallel mounted capacitor, which form an oscillating circuit (6) which can be excited from the outside. The resonance frequency of the oscillating circuit (6) undergoes a detectable modification when a measuring object approaches the proximity sensor (3). With respect to a possible constant sensitivity of the measuring speed for a plurality of different geometeries of the object which is to be examined, the invention is characterised in that the resonance frequency of the oscillating circuit (6) and/or the excitation frequency of the oscillating circuit (6) is influenced in such a manner that the oscillating circuit (6) is always excited with the resonance frequency or with the frequency close to the resonance frequency. Deviations of the frequency of the oscillating circuit from the frequency of the excited oscillator are detected by a phase comparator. A control circuit controls variable or switchable capacitors or inductors. Alternatively, the oscillator is embodied as a VCO.
