Calibrating an LVDT
Calibration

Pre-calibration tuning Use the following procedure for initial tuning of the LVDT sensor
channel prior to calibration. Pre-tuning is especially important if the
LVDT has never been calibrated.
1. Select the Calibration access level.
Stand-Alone— Path: Config > Access Level > Calibration
Automated— On the Station Manager toolbar, select
Calibration in the User Level access box
2. Configure a meter to monitor displacement feedback.
Stand-Alone— Path: Meters > Meter 1 > Signal >Disp.
Automated— From the Display menu on the Station Manager
window, select Meters, and then set up to monitor displacement
feedback.
3. On the Inputs panel (Automated Systems Only), enter
Fullscale Min/Max values that conform with your sensor
specifications.
Typically, you should set the fullscale min/max values according
to the dynamic stroke rating of your actuator. The DYN STROKE
rating is usually printed on a nameplate on the side of the
actuator. For example, if the dynamic stroke rating of your
actuator is 102 mm, you should set your full-scale min to -51 mm
and your full-scale max to +51 mm.
4. Display the Calibration submenu or tab, then set and adjust
parameters.
Stand-Alone— Path: Setup > Disp > Calibration
Automated— Click the Channel Input Signals icon to open the
Inputs panel, and then click the Calibration tab
A. Enter fullscale Minimum/Maximum values that conform
with your sensor specifications (Stand-Alone systems only).
B. Set Excitation to 10 volts.
C. Adjust Post-amp Gain for a 5 volt readout on the meter.
D. Adjust Phase for the maximum output voltage on the meter.
E. Adjust Post-amp Gain for a 9.5 volt readout on the meter.
