Quality Control Process
Every replacement module undergoes rigorous electrical validation. We measure coil resistance with a Fluke multimeter first. Values must match the calibration certificate exactly. Next, we verify sensitivity using a precision micrometer stage. Linearity deviation beyond ±2% triggers immediate rejection. We then perform thermal soak testing at 100°C. This confirms insulation integrity under load. Finally, we inspect connector pins for oxidation. All units ship in anti-static shielding.
Replacement Pitfall Guide
❗ Check the Temp Code. The “10” in this model means 100°C max. Installing this in a 150°C zone destroys the coil insulation rapidly. Verify your operating environment first.
❗ Match Cable Length Exactly. This 1.0m cable length is electrically critical. Substituting a 2m version changes system capacitance. Your gap voltage will drift without recalibration.
❗ Avoid Ground Loops. Never ground the shield at both probe and monitor. Ground loops inject 60Hz hum into your vibration signal. Isolate the shield at the chassis only.
❗ Set Gap Voltage Correctly. Target -10.0 VDC ± 0.2V for this sensitivity. A 0.5V offset causes >10% amplitude error. Do not eyeball this setting.
Keep these in mind and you’ll cut 90% of rework time.
