Quality Control Process
Every replacement module starts with coil resistance verification. We use a Fluke multimeter to confirm factory tolerances. Next, we test linearity on a precision micrometer stage. Deviations beyond ±2% trigger immediate rejection. Thermal soak testing follows at 177°C. This validates insulation integrity under extreme heat. Finally, we inspect connector pins for oxidation. All units ship in anti-static shielding.

Replacement Pitfall Guide
❗ Verify Cable Length First. The 0.5m cable in this model is electrically tuned. Swapping lengths changes system capacitance. Your gap voltage will drift without recalibration.
❗ Check the 50mm Range. This probe handles large strokes. Installing it on a 2mm machine wastes resolution. Match the range to your actual shaft travel.
❗ Avoid Ground Loops. Ground the shield at the monitor chassis only. Double-grounding injects 60Hz hum into your vibration data. Isolate the shield properly.
❗ Set Gap Voltage Precisely. Target -10.0 VDC ± 0.2V during installation. A 0.5V offset causes significant amplitude errors at full scale. Do not guess this setting.
Keep these in mind and you’ll cut 90% of rework time.
