InnoMeter® HVM 6954:2001

Vibration Measurement on Ships

Application

On board passenger and merchant vessels vibrations can occur, which may negatively interfere with the work of the crew or which may diminish the comfort of passengers and crew. In order to assess complaints or to prevent them, measurements acc. to DIN ISO 6954:2001 are suitable, since they allow the evaluation of the vibration severity with regard to habitability on board ships.

By using the InnoMeter HVM 6954:2001, one can easily perform these standards conforming measurements. Additionally, the instrument contains a storage for recent measurement results.

Properties

Compared to common portable instruments the InnoMeter HVM 2631 offers a convenient user menu. The user is guided from the selection of measurement mode to the analysis of measurement data in a logical way. Graphical figures for sensor positioning make multiple axes measurements easy and ensure the measurement is according to standard.

According to the standard, the InnoMeter 2631 is designed for simultaneous measurement in three axes. The usual measurands and weighting filters are integrated. The classification according to the standard (passenger cabins, crew quarters, working areas) with respective standard values is ready to be retrieved. With the choice of the measurement mode, measurement parameters and standard values are adjusted automatically acc. to the standard.

Remarks about the measurements can be noted, measurements can be saved and read into again.

Additionally, the Pro-Version contains frequency analysis of both the unweighted vibration signal and the weighted signal according to occupational health aspects. So the generating components are found quickly and the vibration source can be eliminated.
