A vibration detector suitable for field use and associated systems and methods are disclosed. A representative apparatus includes a vibration sensor in contact with the vibrating structure. The vibration sensor can be in contact with the vibration isolators to eliminate the frequencies of the operator's hand. In some embodiments, a contact force between the vibration sensor and the vibrating structure can be measured using, for example, contact resistors. Since the sensitivity of the vibration sensor can be a function of the contact force, the vibration amplitude measurements can be adjusted for a known contact force to improve the precision of the vibration amplitude measurement.

Finger probe device

A system and method for analyzing a device that includes a mass configured for motion. The system includes a tri-axial accelerometer disposed to detect acceleration vectors of the device and to output three channels of acceleration data, and a user interface receiving the three channels of acceleration data. The user interface is configured to correlate the three channels of acceleration data with a reference frame defined by three orthogonal axes intersecting at a vertex, and includes a display and a selector. The display shows sets of options that represent dispositions of the device with respect to gravity, placements of the tri-axial accelerometer with respect to the device, and orientations of the tri-axial accelerometer with respect to the device. The selector selects one device disposition option, one tri-axial accelerometer placement option, and one tri-axial accelerometer orientation option.
