BENTLY 330180-91-CN
Product Introduction
The BENTLY 330180-91-CN is a 9.0 m system length proximitors for 8 mm eddy current sensors. It converts raw probe signals into standardized outputs for monitoring systems.
This unit features improved RFI/EMI immunity, allowing installation in fiberglass enclosures without signal degradation. It supports both panel and DIN rail mounting, though the “-91” suffix specifically denotes DIN rail mount hardware.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: We check source traceability and verify serial numbers against anti-counterfeit databases. Visual inspection confirms no physical damage or connector corrosion.
- Live Functional Test: Power-on self-checks validate basic operation. We run continuous load tests exceeding 24 hours with temperature logging to ensure stability.
- Electrical Parameter Test: Insulation resistance is verified using a 500 V Megger, requiring >10 MΩ. Ground continuity is also strictly checked.
- Firmware Verification: We read and record internal firmware versions. DIP switch and jumper settings are photographed for future reference.
- Final QC & Packaging: The unit is sealed in an anti-static bag. A QC Passed label with the inspection date is applied before shipping.
Replacement Pitfall Guide
❗ System Length Mismatch: The electrical length of the probe plus extension cable must equal the proximitors length. A 9.0 m proximitors requires a total sensor system length of exactly 9.0 m.
❗ Mounting Hardware Confusion: The “-91” suffix means DIN rail mount. If you need panel mount, you must order the “-90” variant (e.g., 330180-90-CN). They are not mechanically interchangeable.
❗ Cable Termination Issues: Always verify shield grounding at the third terminal block. Improper grounding here is the #1 cause of 60 Hz hum in vibration data.
❗ Power Supply Sag: Calculate total rack power with 20% headroom. Multiple proximitors on a single supply can cause voltage droop during transient events.
❗ ESD Damage: Use an anti-static mat during installation. Dry environments significantly increase electrostatic discharge risks to sensitive electronics.
Keep these in mind and you’ll cut 90% of rework time.
