Each free core LVDT we ship includes a small black mark on one end of the sensor body and a matching mark on one end of the core. These marks indicate the orientation in which the core was factory-calibrated to the LVDT and are intended to demonstrate the proper orientation during installation.
Align the marked end of the core with the marked end of the sensor body. This preserves the factory calibration and ensures correct alignment for the most accurate and repeatable position measurements.
If the core is installed in the opposite direction—meaning the marked ends are on opposite sides—the sensor will still function as normal, but a system recalibration is recommended.
