System description
4.2 VIBCONNECT RF sensor unit
The sensor unit is the transmitter and receiver unit attached to the
machine. Each sensor unit comes with one or two connected sensors
for the simultaneous measurement of vibration and temperature. By
separating the sensors from the radio unit, it is possible to position
the components in the most suitable locations on the machine:
• For sensors, these are the points with the highest signal level.
• For the transmitter / receiver, it is the point of best radio recep-
tion.
The sensor unit requests the measuring tasks from the bridge and
performs them by means of the connected sensors. For vibration
measurements, only the related time signal is recorded. For each
measurement location, up to four vibration measurements and
one temperature measurement can be configured.
The sensor unit can be powered from three different sources:
• Battery
• 24 VDC
• Energy harvester
4.2.1 Power options
Battery
The sensor unit is powered by two lithium batteries. The battery
charge level is automatically signalled to the bridge at each mea-
surement transfer and displayed in OMNITREND. If a battery needs
to be changed, a warning is displayed when the software is started.
The batteries are not included in the scope of delivery and must be
purchased separately.
• Battery type: 3.6 V lithium, size C
• Manufacturer: e.g. Tadrian, type: SL-2770
Sensor unit with two sen-
sors, for vibration
and temperature mea-
surement respectively.
