Product Introduction
BENTLY 330101-00-28-10-12-05 is an 8mm eddy current proximity probe for shaft monitoring. It converts tip-to-target distance into a proportional voltage signal for your monitoring system.
This industrial automation unit offers a linear range of 2mm with 1.2m total system length. It maintains stability across -35°C to 177°C operating temperatures.

Quality Control Process
We verify every BENTLY 330101-00-28-10-12-05 before shipment. First, we measure DC resistance on the probe coil using a precision LCR meter. Values outside ±5% fail immediately.
Next, we perform a gap-voltage calibration check against a certified steel target. Linearity must stay within 1% across the full 2mm range. We also inspect the micro-coax connector pins under magnification for corrosion or bending.
Finally, each replacement module gets sealed in anti-static shielding with desiccant. This prevents moisture damage during transit.
Replacement Pitfall Guide
❗ System Length Mismatch: The “12” in your part number dictates a 1.2m total electrical length. Probe cable plus extension cable MUST equal this exactly. Even 10cm of error ruins calibration.
❗ Ground Loop Noise: Never ground the probe shield at both ends. This creates a ground loop that mimics vibration signals. Ground only at the proximitors side.
❗ Thread Engagement: The 3/8-24 UNF thread is fine-pitch. Cross-threading destroys the housing seal. Hand-start only, then torque to spec.
❗ Cable Routing: Keep probe cables away from VFD output lines. High-frequency switching noise will corrupt your displacement signal.
Keep these in mind and you’ll cut 90% of rework time.
