Span Test
1.
Gently push the sensing head moving beam to the right. The LVDT output should
steadily increase until a level of 0.75 to 1.0 V AC is achieved.
2.
Gently push the sensing head moving beam to the left. The LVDT output should
steadily decrease until zero is reached and then start increasing again to 0.015 to
0.5 V AC.
3.
Ensure the LVDT output always returns to 0.10 ± 0.05 V AC, (to the right side of zero)
when pressure on the moving beam is released.
Sensing Head Level Test
1.
With the voltmeter still connected to the LVDT output, hang the test weight directly
off the sensing plate.
2.
Check to ensure that the LVDT output does not change by more than 0.01 V AC.
Note:
•
The LVDT core must not contact the inside of the LVDT over the range of core
travel.
•
The actual LVDT core travel during this procedure is less than 3 mm (1/8").
Note:
•
If the change is greater than 0.01 V AC, adjust the sensing head level, (refer to
“Installation” on page 4) until the change with and without the test weight on the
sensing plate is less than 0.01 V AC.
•
Remove the test weight and readjust the LVDT Output Zero, if necessary. If the
level test is performed after the integrator has been calibrated, a new integrator
Zero and Span calibration, Span Adjust, and Factoring, should be performed.
