3. Description
.
The WSD10TII is a datalogger designed to measure 3 input channels to acquire outdoor temperature and inclination, with storage functionality
of samples acquired.
Inclination measurement is performed by a three-axis accelerometer, which allows the device free orientation related to the horizontal surface.
4. Thermometer: working logic.
The value contained in CH1 channel can be sampl ed every “
Threshold/Following interval
” as the
other channels.
5. Inclinometer: working logic.
a. Measure.
The datalogger furnishes X and Y axis values related to sampled movements after installation and
its position zeroing Such values are reported on channels CH2 and CH3 respectively.
If a value exceeds the maximum or minimum movement range, the measure will be declared as
“invalid” .
Normally these values are the result of a progressive average updated every “
Threshold/Following
interval
” recorded and sent to the gateway every “
Measure interval
”.
For the average to be done correctly , it is necessary that the “ Follower ” function , on CH2 and CH3 channels (active by default), must be enabled.
Otherwise, the average will be performed with the cadence of the " Measure interval ".
The setup of these intervals is configurable and adjustable using
WineCapManager
software or cloud support.
b. Measure threshold.
Two thresholds for each inclination channel can be setup: two thresholds for CH2 and two thresholds for CH3.
Measure sample will be compared with thresholds values with interval obtained by “
Threshold/Following interval
” value.
c. Value following – Step answer.
Every “
Threshold/Following interval
” will be compared to the “
instant value
” (
average acquired in a time frame of 8 seconds
) with the current
sample.
If the deviation is greater than “
Delta increase
” value or less than “
Delta decrease
” value, configured in setup, measure is placed equal to the
“instant value” and the average initialized again to that value.
This event will be notified with recording and sending the new measure value.
Properly adjusting “ Delta ” values becomes possible manage movements and react to unexpected events without waiti ng for periods introduced
by average.
The device DOES NOT answer to SHOCK events and cannot be intended able to display dynamic events. An
“
unexpected event
” must be
intended as a significant movement related to the quiet position of the device.
d. Installation position zeroing.
After fixing and installation operations, a “6+2” command (refer to
Picture 6 - Status table – Wireless mode
) can be issued which performs the
reset of inclination channels.
The command starts a first acquisition which defines the device’s absolute position and, consequently, the axis rotation to a lign internal
references. At the end of the procedure, the zero value and the axis position will be saved in memory to be recovered in case of device restart.
This procedure lasts around 5 minutes.
