摘要： Measurement probe (1) is used for measuring thin layers (19) on base material (20) using a magnetic or eddy current process. On probe housing (5) above a stop for guide means (3) with measurement sensor (12) and measurement pole (13) sliding element (2) for measurement sensor (12) is guided to move in the longitudinal axis of probe housing (5) as limited by a stop. Between sliding element (2) and stop (9) on guide means (3) there is first helical spring (4) by which sliding element (2) is elastically supported relative to measurement sensor (12). Between stop (9) on guide tube (3) and lower abutment (30) on probe housing (5) is second helical spring (10) which interacts with first helical spring (4) and elastically supports measurement sensor (12) in the rest state at a distance above opening (5a) for measurement pole (13) in probe housing (5). By means of the elastic arrangement of the guide means with the measurement sensor in the probe housing between the interacting helical springs a very small load pressure of the measurement pole on the layer to be measured is achieved with the measurement sensor lowered. When measuring with the invention measurement probe, first the probe body with the probe foot is seated on the layer to be measured. Only then is the measurement sensor slowly placed on the surface by actuating the sliding element, in a damping and elastic manner. The measurement sensor withdrawn into the interior of the probe body is held in the relieved unused state of the probe and does not project above the seating surface of the probe foot.

摘要： An improved method and apparatus for monitoring the thickness of a film includes a sensor roll which cooperates with a compliant roll to form a nip through which the film passes. As the two rolls rotate relative to each other, magnets disposed in the sensor roll are sequentially moved to and from the nip. As a magnet moves by the nip, the field emanating from the magnet is concentrated by a body of material having a relatively high magnetic permeability and disposed in the compliant roll. This results in an induced voltage being generated in a sensor coil. The output from the sensor coil is transmitted to control circuitry which effects operation of a suitable apparatus to control the thickness of the film.

摘要： A magnetic thickness gauge is disclosed wherein a balance arm is pivotally mounted in a housing with a spring providing a bias force to counteract a magnetic attraction of the balance arm toward a base of a coating to be measured. The balance arm is provided with a probe assembly including a magnet selectively positionable with respect to a spherical contact member of either a particular alloy of aluminum, iron and silicon or of tungsten carbide. The housing is preferably provided with supports at either end of the gauge. A balance arm is moved by way of a protrusion provided between the probe assembly and an adjustment knob for the spring with a scale and pointer indicating the thickness of the coating to be measured.

摘要： A gauging apparatus for sheet materials and the like comprises a surface follower body (14,20,30) adapted to be constrained without substantial solid bodily contact and guided (e.g., by gas bearings between 32 and 36 and 38) for movement along a surface follower path that intersects the path of a traveling sheet (10) to be gauged. The body has a passage (46) adapted to carry a flow of pressurized gas to be discharged against one surface of the sheet. The discharge of the gas is effective when the body is at a predetermined distance from the surface to generate a levitating force (on 20) urging the body away from the sheet surface. Means (70,64,62) responsive to the pressure of the gas in the passage exerts on the body (at 64) a counteracting force that tends to move the body closer to the surface. The counteracting force increases when the pressure increases and decreases when the pressure decreases, and coacts with the levitating force in such a manner that the predetermined distance of the body from the surface is normally maintained substantially constant and is relatively unaffected by minor variations in the pressure of the gas in the passage.

摘要： A coating thickness and surface comparator for measuring the thickness of nonmagnetic coatings (28) or roughness on ferromagnetic base materials. A permanent rod magnet (6) and a ferromagnetic rod (16) are supported by nonmagnetic slides (12, 14) parallel to one another. When a standard base (24) is placed at one end (22) of the rod magnet (6) and a coated or roughened base (30) is placed at the other end, the slides (12, 14) are pushed together toward the middle of the rod magnet (6). The coincidence of the slides (12, 14) varies from the middle of the bar magnet (6) in proportion to coating thickness (28) or roughness.
