Norsonic Nor133 and Nor136 Multi-Purpose Vibration Meter

The Norsonic Nor133 and Nor136 Multi-Purpose Vibration Meter is designed for measurement of whole body and hand-arm vibration measurements. Optional upgrades allow for the measurement and analysis of vibration in buildings, ships, vehicles, and public transport systems in accordance with international and national standards. The units are also suitable for general machine vibration. User interface is simple and easy to use whilst the large backlit display and the small physical dimensions make the unit ideal for field use. 

Optionally, the Nor133 and Nor136 may record the vibration signal onto an SD memory card simultaneously with the measurement, for later and more sophisticated signal analysis in the PC program NorVibraTest. This option gives the opportunity to assess the same measurement at a later time with any desired weighting functions, e.g. if standards have changed or to new criteria. The measurement does not need to be repeated on a machine or vehicle if the standards change.

Set to the whole body mode, the 6-channel Nor136 option may record and measure up to 6 vibration channels simultaneously. A comprehensive WB assessment should be carried out in a 6-channel mode, where 3 channels measure the WB vibration of the subject and the other 3 channels measure the vibration of the source. The correlation of these data can then be examined in the NorVibraTest program to determine the transfer function, of the driver's seat for example, so unknown influences or artefacts can be removed from the WB measurement.
