Proportional voltage measurements.
Common thrust/axial position measurement. Measures the offset and
direction of movement.
Proportional voltage measurements.
The measurement of shaft bow (the shaft peak to peak displacement) at
slow roll speed by either of two methods (with or without a speed
input).
Comment
Calculates the peak to peak shaft absolute radial displacement
measured from the sum of:
A shaft to case relative displacement (eddy current probe)
measurement, and
A case absolute displacement measurement from an integrated velocity
transducer or double integrated accelerometer that is mounted in-line
with the eddy current probe.
The first channel of the pair must be the accelerometer or velocity sensor
and its Measurement Type must be one of:
absolute vibration (A to D)
absolute vibration (AV to D)
absolute vibration (V to D)
The second channel of the pair must be the displacement sensor and its
Measurement Type set to Shaft Relative (LP/HP).
