Whole-body Vibration Dosimeters

Our innovative vibration dosimeter allows for vibration measurements to be taken of whole-body vibration exposure according to ISO 2631. Its autonomous sensors that do not need to be wired during measurements and automated artefact detection provide for a user-friendly implementation and use (can be used by non-experts).

Stored data is downloaded from the sensor(s) at the end of the working period to a smartphone or a PC using a Bluetooth connection.

The software allows for the automatic computation and display of workers’ exposure to whole-body vibrations and indicates how such exposure compares with the limit and action values defined in the vibration Directive.

The set of whole-body vibration meters (Vib@Work Seat, Vib@Work Floor & Vib@Work Detect) can measure the vibration exposure of either seated or standing operators. In addition, when used in conjunction, seat efficiency can also be measured (i.e. S.E.A.T. factors).

The vibration dosimeter is the perfect tools to monitor and maintain workers’ safety using any lifting equipments or vehicles that generate vibrations. It ensures that the workstations are not subjected to levels of harmful vibrations.

CONFIGURATION OF TYPICAL MEASUREMENT – SENSOR(S) USED

Vib@Work Seat – The whole-body dosimeter

Vib@Work Seat (formerly “Evec”) is a dosimeter for measuring vibrations transmitted to the whole body. It allows for the measurement of the vibration levels experienced by seated operators in accordance with European Directive 2002/44/EC. The sensor is a semi-rigid interface to be placed on the driver’s seat.

Seated operator exposure

(1) Vib@Work Seat

Vib@Work Floor – The floor vibration dosimeter

Vib@Work Floor (option) is a dosimeter for measuring floor vibrations.

Used in combination with the Vib@Work Seat, it allows for the calculation of seat efficiency factors, also called S.E.A.T. factors.

Vib@Work Detect – The standing operator dosimeter

Vib@Work Detect (option) is an external and autonomous presence detector (for use in combination with Vib@Work Seat or Floor) that allows for the calculation of the vibration level experienced by standing operators in accordance with European Directive 2002/44/EC.

These three sensors communicate with the EvecSensorDuo software installed on your PC through a wireless connection. No wires are needed.

Stand-up operator exposure

(3) Vib@Work Detect

EvecSensorDuo Software

This software allows users:

To select the required measurement configuration (seated operator exposure,
standing operator exposure or seat efficiency measurement, S.E.A.T factors)
To switch ON the sensor(s) according to the selected measurement
To access – through a wireless connection – measurements made by the sensor(s).
To automatically and easily calculate and display the final results of the vibration measurements
(such as daily vibration exposure A(8) and/or the S.E.A.T. factors for example).

S.E.A.T. Factor

(1) Vib@Work Seat

(2) Vib@Work Floor

WBCheck (Option)

Vib@Work WBCheck is a check bench for “whole body” dosimeters allowing for the acceleration measurement of “seat” or “floor” sensors to be validated along the 3 measurement
axes X, Y and Z

EvecViewerDuo Software (Option)

This software allows users:

To display time histories of acceleration levels acquired with Vib@Work Seat, Floor and Detect sensors during vibration exposure measurements
To interact with the acceleration graph to edit ranges, zoom, pan
To define exclusion ranges, besides the ones that are automatically created by the sensors and activate or deactivate them in order to compute their impact on daily vibration exposures
To define groups of exclusions, which allows all exclusions in a group to be simultaneously activated or deactivated
To highlight peaks in acceleration measurements
To annotate measurement ranges of interest
To import voice records (which have been taken during the vibration measurements) into EvecViewerDuo, where you can play them and hence determine the impact of particular driving or operating events on vibration measurement results
To simulate different utilization times of the vehicle or machine
To export results in 3 different formats (evc, spreadsheet, text)
To copy graphs and measurement results to the clipboard and paste them into a work processor for reporting purposes
