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.
