Description

Eccentricity is the measurement of shaft bow at slow-roll speed. This can be caused by:

lFixed mechanical bow

lTemporary thermal bow

lTemporary bow due to any sort of sag or bow at rest (sometimes calledgravity bow).

The 3300/40 Eccentricity Monitor provides on-line eccentricity monitoring. Itallows you to identify the 

amplitude of thermal or gravity rotor bow. The monitoris suitable for virtually all types of rotating and 

reciprocating machinery,continuously measuring and monitoring one channel of eccentricity.

The monitor provides two types of eccentricity indication:

lDirect eccentricity: the instantaneous eccentricity value.

lPeak-to-peak eccentricity: the difference between the positive and thenegative extremes of the rotor bow.

The monitor also provides information on Gap Voltage and Threshold Voltage.
