A dendrometer, comprising a single mechanical element functionally holds a sample under test via a spring-element in the element that draws two arms firmly against the sample. The spring section of the single mechanical element can be serpentine, or any other shape providing the desired spring constant and range of motion. The one or more spring members extend between the first frame member and the second frame member, wherein the one or more spring structures are nonrigid (extensible and compressible) such that the second frame member is movable relative to the first frame member. The dendrometer comprises a toothed socket on an end of each arm to allow adjustment of the range of clamping. In at least one example, a magnet or actuator attached to one arm, and a Hall effect or other positional sensor, is attached to the alternate arm.

The subject matter of the invention relates to a method for the automatic technical diagnosis of rotating machines, including detection of faults in rotating machines, in particular vibration measurements of rotating machines by the automatic detection of changes in the signals of machine vibration. The method consists in that monitoring and diagnosis are performed in terms of identifying both the assemblies or parts of an object of the rotating machine subjected to the diagnosis, in such a way that vibration data are recorded in the form of a vibration signal from at least one vibration sensor (2) mounted on the housing of the mechanical elements of the rotating machine (1), wherein each subsequent vibration signal is recorded at the same length and at the same sampling frequency. Then, collected vibration signals are processed in a vibration data acquisition unit (3) equipped with a reductive-redundant mechanism (4) by means of which the vibration signal is modified by calculating the values of spectral components in the domain of frequency or orders and the values are segmented relative to subsequent tested spectral resolutions on the basis of current scale of class intervals. Then, an averaged spectrum is calculated and added to the state matrix and a statistical measure of the comparison of spectral amplitudes is calculated for individual class intervals at the standard score measure and the procedure is repeated for each tested spectral resolution in the range from the value equal to the inverse of the vibration signal length to half the sampling frequency. Finally, the results of the vibration growth index are saved, then are sorted from the highest to the lowest value thus allowing the potential occurrence of a fault to be determined in terms of identifying both a specific assembly or part of the rotating machine (1).
