Channel Type: gSE
Input Tag Measurement Type Selections Comment
gSE Spike Energy (gSE) is a processing technique capable of detection of low
energy impacts. The measure is suitable for early detection of faults in
rolling element bearings or gears and detection of other periodic or
random low energy impact events.
Channel Type: Static (DC)
Input Tag Measurement Type Selections Comment
Rod Drop Rod Drop A triggered position (rod-drop) measurement that is taken at a fixed
(consistently the same) position of the rod during the stroke.
Differential Expansion Comp. Differential Exp. A/B (Axial) The measurement of shaft axial displacement using a pair of axial eddy-
current-probe monitoring a shaft collar target such that the
measurement range is optimally the sum of the ranges of the individual
probes.
Differential Expansion Ramp Differential Exp. A/B (Radial) The measurement of differential expansion with axial/radial eddy-
current-probe pair viewing concave or convex ramp shaft.
