T-218T 2-Axis Turbine Target
The T-218T turbine target works much the same as reference
targets. The target fixture (A-502A) is swept into the center of
the bore using the A-501(A) sweep unit, then the target is placed
in the fixture and the reading is taken. A positive vertical reading
means the diaphragm is higher than the reference bores. A
positive horizontal reading means the diaphragm is to the right of
the reference bores. Since the data is live, the diaphragm can be
adjusted until the reading is zero (or to an offset determined by
the engineers).

A-1511 Wand Bore Fixture
The A-1511 Wand Bore Fixture
speeds data taking for steam turbine
bores with diameters from 10 in. to
96 in. (254 mm to 2.44 m) and
provides high levels of repeatability
for faster measurement-taking to
help reduce overhaul alignment
times by up to 50 percent. The
fixture uses two fixed-length legs
approximately equal to the radius of
the bore, one leg with a measuring
tip and one for support.
