Although EVEC exhibits advanced
functions, it has been designed to be used by non-experts. The
EVEC sensor is placed on the driver’s seat, without mechanical
or electrical connection. A few clicks are enough to prepare the
measurements campaign and retrieve the results. This is done by
the EVEC software which can be installed on the user laptop or a
Pocket PC, both equipped with a Bluetooth® connection.
No user data sorting, handling or computing is required. Thanks
to the presence of the detection device integrated into the EVEC
sensor, the vibration exposure, as well as the A(8) value as
defined in directive 2002/44/CE, are computed immediately from
the signals of the 3-axis vibration accelerometer. The EVEC
software also shows how the vibration levels measured compare to
the action level and exposure limits specified in the
directive. |

Any measurement campaign includes unwanted effect which can
jeopardize the correctness of the readings. For example, when
the worker sits on or stands up from its seat, the sensor will
measure shocks which, if taken into account, will distort the
computed exposure levels. The EVEC includes an automatic
rejection software able to discard these unwanted events while
computing the exposure levels. |
