The
Alternative to Wires!
PERMAPLUMB is a laser based system which replaces the
time-consuming wire method. It measures the plumbness of vertical turbine shafts. A
self-adjusting mirror –always parallel to the horizon– reflects a class I laser
beam into a vertically mounted transducer. Mirror and transducer are attached by magnets
to the turbine shaft. From a single 270 degree shaft rotation the system calculates and
displays angularity and corrective moves and even confirms their validity. A MOVE function
allows monitoring of corrections as they are being made. Resolution is better than
0.00002"/ft. Adjacent turbines can continue to operate since the system is vibration
insensitive.
