摘要： In the rolling probe, the measuring pole is designed as a rotating, rotationally symmetrical roller (4), such as a disk, cylinder or sphere, which directly contacts the surface of object to be measured (5) and is placed in the range of a sensor system. As a result, the maximum possible signal deviation can be fully used for the measuring. An increased measured value resolution and measuring accuracy especially in the measuring of thin sheets is achieved. Further, the actual thickness measuring takes place at the contact point with the layer to be measured. Thus, a true "one-point measuring" is involved.

摘要： A gauge probe for a handheld combination coating thickness gauge allows the combination coating thickness gauge to measure both nonferrous coatings on ferrous substrate and nonconductive coatings on conductive nonferrous substrate. The gauge probe enables the combination coating thickness gauge to determine automatically, with a single probe, the substrate characteristics, and to effect a measurement of the coating thickness on that substrate. The technique used to measure coatings on a ferrous substrate utilizes a permanent magnet to provide a constant magnetic flux and a Hall sensor and thermistor arranged to measure the temperature-compensated magnetic flux density at one of the poles of the permanent magnet. The flux density at the magnet pole can be related to a nonferrous coating thickness on a ferrous substrate. The technique used to measure nonconductive coatings on a conductive nonferrous substrate utilizes eddy current effects. A coil near the gauge probe tip is excited by an alternating current oscillating between about 6 MHz and about 12 MHz. The coil sets up eddy currents on the surface of the conducting substrate. The resulting eddy currents set up an opposing magnetic field which in turn have an effect on the excited coil. The eddy current effects on the coil are quantified, and the degree of the eddy current effects on the coil are related to the nonconductive coating thickness on a conductive substrate. The gauge probe detects the substrate type and automatically determines the coating thickness on the detected substrate.

摘要： A contacting caliper gauge measures the thickness of a moving sheet material. The gauge has two heads, one on either side of the sheet. The sheet contacting pads of the caliper gauge are aerodynamically designed to limit and/or reduce the tendency of boundary layer air travelling with the sheet to raise the sheet-contacting pads off of the sheet surfaces.

摘要： A method of and apparatus for measuring the layer of coating thickness of non-magnetic substances on a ferromagnetic parent material by the magneto-inductive method or of non-metallic substances on a conductive parent material by the eddy current method. This is done with the use of a probe whose coil inductance is evaluated as a criterion for the thickness of the layer to be measured. An adjustment to the geometry and the magnetic properties of the specimen are made before the first measurement. In the adjustment, at least one non-magnetic or non-conductive foil is disposed or are consecutively disposed between the probe and the surface of the coated specimen and the measured data obtained then and in the subsequent measurements are fed to a microcomputer. In the semiconductor store of the micro-computer, the non-linear relationship between the coil inductance of at least one probe and the distance between the probe and the parent material is being or has been stored in the form of at least one values table and in which the layer thickness values of the foils are being or have been stored. The microcomputer calculates the thickness values of the layer material from the measurement data fed to it and from the stored data.

摘要： In a method of checking the insulating sheath on a wire or cable leaving an extruder, the external diameter of the insulating sheath is continuously determined over the whole circumference by means of a first measuring apparatus and the wall thickness of the insulation is continuously detected over the whole circumference by means of a second measuring apparatus. The measured values are supplied to a computer which, inter alia, continuously determines the difference between the maximum and minimum wall thicknesses found (W.sub.max -W.sub.min). Eccentricity and minimum wall thickness of the sheath are calculated from this difference and from the measured external diameter of the insulation and the diameter of the conductor of the wire or cable, and are indicated in a display device. The measurement is thus rendered largely independent of fluctuations in sensitivity of the measuring apparatus for the wall thickness of the insulation. An apparatus for carrying out the method comprises the respective measuring apparatus and a computer for effecting the required calculations.

摘要： An electro-magnetic thickness measuring probe has a pot core which has a central bore, a pot chamber coaxial to the central bore accommodating a winding, and a pot rim. A pole-piece has one end fixed into the central bore and a free front-face with a coaxial recess machined therein such that an outer shell remains around the recess. A hard-metal pin is seated in the recess and has a front-face forming a crowned contact surface which stands a little proud of the pot rim. A coaxial annular disk made of highly permeable magnetic material has an outer edge in contact with the pot rim, a non-magnetic slot, and an intrados-radius surface having a diameter greater than the diameter of the pole-piece but significantly smaller than the diameter of the pot chamber. The intrados-radius surface lies close to the front-face of the pole-piece, whereby the magnetic resistance between the intrados-radius surface and the outer shell is significantly greater than the magnetic resistance between the intrados-radius surface and the free front-face when the measuring probe is set down on a surface.
