Abstract: Devices to measure bearing wear are known for bearings such as rod-ends, wherein the rod-end must either be removed completely from its installed position or relocated relative to the device each time wear in a different axis is to be measured. Such devices also tend to be relatively large and cumbersome. The present invention provides a device 10 which is a fully portable light-weight apparatus that precisely measures bearings in two axes. When employed for the purpose of assessing bearing wear, the invention is capable of obtaining the measurement in confined spaces, without the need to remove the bearing from its fully installed position or reorient the bearing housing to facilitate both measurements. By using the disclosed apparatus, a user may ascertain the serviceability of a bearing by detecting the level of wear in the bearing allowing timely replacement and/or repair.

Abstract: A method and device for metrologically differentiating material regions, namely majority regions and minority regions of a page-like, web-like or sheet-like material. At least one sensor receives a measuring signal of variable amplitude, the amplitude being variable depending on the material region located in a spatial detection range of the sensor. The amplitude is increased by a controllable amplifier. The material is moved relatively to the sensor such that majority regions are located in the spatial detection range of the sensor more frequently than minority regions. The method is characterized in that in phases, in which majority regions undergo examination by means of the sensor, by means of the amplifier regulation of the amplitude to a set point is carried out and the sensor generates a signal “majority region”, and that in situations, in which the amplitude undergoes a sufficient change, the sensor generates a signal “minority region”.
