Installation, Operation & Maintenance of the Wireless Sensing Family

A cellular USG is used for mobile applications, like trucks and trailers,
where LAN or Ethernet connectivity is rarely available.
In some cases, networking setup (like firewall), can cause delay in
deployment. In that case, cellular units provide the easiest way to get a
system up and running independent of the local IT configuration.
Q: When should I use the Cellular USG in stationary application?
A:
A cellular USG can be used in a stationary installation when a LAN
connection is not available.
Q: How do I know how many R-Sensor to use in a stationary
application?
A:
Number of Resident Sensors varies between sites. It depends on
communication blockers such as Metal doors, concrete walls, racks,
architecture, level of fluids in the products. The toughest the blockers the
more Resident Sensors you need in order to bypass the blockers.
Q: How do I know the battery level & status of the R-Sensor ?, U-
Sensor
A:
CartaSense system provides statuses of the various system
components. One of them is the battery status. Status data is stored in
the database. When integrating CartaSense system, the application
developer can use the data for any manipulation required such as battery
status display, setting thresholds, alarms, etc.
Q: Can the interval between measurements be changed?
A:
yes. The measurements time interval can be changed either remotely
or during manufacturing procedure.
Q: In a cellular USG, what will be the data traffic?
A:
A single sensor generates around 120KB per month. In truck
installations with 30 U-Sensors, the average traffic is 3.5 MB per month.
Traffic values may vary depending on number of sensors, measurements
time interval, etc.
