StatusCheck Operators Manual
System Overview:
This manual provides the necessary documentation for the installation and
operation of the Timken StatusCheck™ Condition Monitoring System. The
StatusCheck System is a cost-effective online monitoring system for
predicting the health and operating condition of machinery components.
The StatusCheck end node is self-contained with battery powered sensors
and electronics. The end node attaches directly to the outer frame or
housing of a machine. It uses wireless radio frequency (RF)
communications to transmit sensed physical characteristics (vibration
parameters and temperatures) of the machine. A transmission distance of
up to one kilometer (
1 ⁄
2
mile) line-of-sight (open field) or 300 meters (328
yards) in a typical plant environment can be achieved. Multiple
StatusCheck end nodes (up to 100) can be in use on one or more
machines, all of which send their signals back to a controller.
The controller connects through a serial, USB or Ethernet port to a PC that
displays the data. The data consists of ambient temperature, probe
temperature and vibration parameters from a dual axis accelerometer in
acceleration or velocity. The StatusCheck software is used for real-time
monitoring, data logging and triggering alarms once the collected data
exceeds user-defined thresholds indicated by yellow and red conditions.
By observing the data over time, the user can evaluate the operating
condition of the machines. The data plotted in Figure 5 versus time either
can be operating temperature or a vibration measurement. The machine
measurement trends increase as the machine approaches a failure mode.
The yellow line indicates a warning condition, whereas the red line
represents a critical alarm condition. The goal is to detect conditions that
require maintenance action before a problem becomes severe and causes
unplanned machine downtime or collateral damage.
Applications:
The StatusCheck monitoring system is suitable for a wide range of
applications. The machines that can be monitored include pumps, fans,
rolls, gearboxes, motors, bearings or other industrial applications requiring
the measurement of steady-state temperature and vibration.
