Description.
The
WSD10TGII
is a datalogger with 4 input channels to acquire mechanical schock, inclination and temperature, with storage
functionality of samples acquired.
2.
“Sentry” feature.
The
WSD10TGII
’s main feature is to measure landslides and or avalanches strikes against protection barriers: when the
acceleration, measured on channel 2 of the
datalogger
, exceeds a user-set threshold, the
WSD10TGII
sends immediately to the
basestation
the information of “threshold trespass” and related warning.
This information can be later processed according to the
basestation
model whose the
datalogger
is enrolled.
For models provided with ModBus communication protocol (
MWDG-MB, MWLI-MB, MWLI-MB-4AO
), the information can be picked-
up directly on the ModBus register and managed through third party external intelligence (
PLC, PC, ecc.
).
Concerning the
MWLI-MB-4AO basestation
, the received information let the
basestation
to immediately close either relay
equipped onboard and physically turn on an external alarm device.
Please note:
the
datalogger
must not be installed upside down, with ±180° tilt because the result means a discontinuity point and data
acquired are wrong;
the
datalogger
stores an acceleration value of 0 G when in static position. During the threshold setup, the gravity
acceleration must be considered and it’s divided by three axis if the
datalogger
installation is not perfectly vertical.
Evaluating the tilt values, gravity force vector distribution can be rised again;
the acceleration threshold must be set as “higher” and must have a minimum value of 1.1G. This value takes in account
that the gravity acceleration constant is always present. The value is internally compared with accelerations measured on
three axis and, in case of threshold value excess even just one axis, the
datalogger
sends the event warning every 30
seconds until the end of warning condition, warning condition event included;
the warning value is the maximum value acquired sampling at 100Hz on three axis.
