Figure 5: Operation of StatusCheck™
How it Works:
The StatusCheck system collects
temperature and vibration signals for
a one second period during a
transmission cycle. The vibration signal consists of 4,096 data points over
this time interval. The vibration data is then statistically parameterized into
five main statistical readings for each accelerometer axis. This
parameterized data, along with the temperature readings, is transmitted to
a controller, which connects to a PC for analysis. The StatusCheck real-
time tracking software compares the parameterized data to adjustable
user-defined thresholds and to trigger alarms. This technique allows easy
interpretation of a machine’s operating condition over time.
It is important to note that this system will not indicate the exact system
problem only that a problem exists. A more advanced diagnostic system
can be used once a problem is identified. This system is fully turn-key and
installs quickly, with minimal required training, for a simple assessment of
a machine’s operating condition.
System Components:
At a minimum, the system is composed of one controller, one end node
and one software package. Routers may be required to extend the range
from the end node(s) to the controller. The system can be composed of a
maximum of 100 end nodes per controller. Mounting fittings, mounting
plates, spare o-rings, cabling and spare batteries also are available from
Timken. Contact your Timken representative to obtain these items.
End Node:
The StatusCheck end node operates in the 2.4 GHz ISM band and is a
direct sequence spread spectrum. There are many benefits to using a
spread spectrum transmission scheme. The StatusCheck device complies
with FCC- and EU-based RF requirements and will typically not interfere
with other wireless devices.
Testing has been successfully performed in plant environments without
significant loss of data. Transmission distance is decreased and data loss
is increased with obstructions and noise interference.
