G-5
Mils/Inch
A unit (normally English) used to describe the angle of one shaft centerline
to the other. It is equivalent to milliradians. It can also be expressed as rise/
run (1° = 17.45 mils/inch).
Modem
A device that enables remote communications between the host computer
and the analyzer over telephone lines.
Notes
Specific observations that can be stored in each alignment job along with
the collected data. These observations can be predefined notes or user-
defined notes that have been created via the analyzer’s keypad, or a com-
bination of the two methods.
Off-line to On-line Running Condition
Movement of shaft centerlines associated with (or due to) a change in pres-
sures, temperatures and other forces between the static and operating con-
dition.
Offset
Distance between rotational centerlines at any given normal plane, usually
measured at the coupling midpoint.
Perpendicular
At right angles (90°) to a given line or plane.
Pipe Strain
Casing and shaft distortion caused by improper pipe flange fitup.
Predictive Maintenance
Technology of periodically monitoring the actual condition of machines to
discover faults, to determine probable time of breakdown, and to provide
scheduled downtime for repair that avoids excessive cost and lost produc-
tion.
