Data collection overview
The CSI 2600 is a continuously monitoring online system. Once configured, it will collect
both periodic predictive data (Trend, Spectra, and Waveform snapshots, multiplexed two
channels at a time) and Transient measurements (continuous unbroken waveforms for
extended periods on up to all 24 channels). Predictive data can be stored in an AMS
Machinery Manager database. Sections of the transient waveforms can also be extracted
into archives either on-demand or based on alarm events.
For the Transient channels, the CSI 2600 continuously stores waveform measurements on
a Hard Disk Drive (HDD). This can be either the internal 80 GB HDD or an external NAS
drive (up to 250 GB). When the drive fills up, the system will begin overwriting the oldest
measurements in a First In First Out (FIFO) manner.
Data is stored at a rate of approximately 40 MB per hour per channel. The following
method can be used for estimating the amount of time that data can be streamed to the
HDD before it begins to FIFO. First determine the number of channels that will be
commissioned for Transient operation; then use this equation:
Storage Time (in hours) = HDD size / (number of Transient channels x 40 MB/hr)
.
For example, consider a pump monitoring system which has a total of 14 sensors. This
could include 4 pairs of radial shaft vibration probes, 2 thrust probes, 1 case expansion
sensor, 1 eccentricity sensor, and 2 horizontal accelerometers. In addition to collecting
periodic prediction data, the 8 shaft vibration probes are also commissioned for Transient
data collection.
80,000 MB / (8 channels x 40 MB/hr) = 250 hours (approximately 10 days)
So, the internal HDD will store data for approximately ten days before starting to FIFO.
The CSI 2600 is both a continuous monitoring system and a portable monitoring system. It
can be moved from one piece of equipment to another, with data from each piece stored
in separate databases. See
for more information.
CAUTION!
Changing databases will reinitialize the Transient HDD, which eliminates all stored data.
Extract any data before changing databases.

Data recorder modes
Data collection to CSI 2600 internal memory
When the CSI 2600 is running and the computer is disconnected, the unit runs in DAT
recorder mode, optimized for turbomachinery transient data. Waveforms from up to 24
channels, including tach striping, are recorded continuously and simultaneously. If all 24
channels are streaming transient data, the internal 80 GB HDD will store approximately 90
hours of data before it begins to FIFO.
