Description
Bently Nevada 330180‑12‑00 — 3300‑XL 8mm Proximitor Sensor
Product Overview
The 330180‑12‑00 is the 3300‑XL 8 mm proximitor sensor, the signal conditioning unit for standard 8 mm eddy‑current proximity probe system. It excites the probe, processes gap‑impedance signal and outputs proportional DC gap‑voltage for vibration and thrust‑position monitoring. It works exclusively with 330101 / 330103 / 330105 series 8 mm probes and 330130‑xx‑xx‑00 extension cables. Complies with API 670, widely deployed on turbines, compressors and critical rotating equipment.
Critical Compatibility Warning:
- Only for 8 mm 3300‑XL probe system. NOT compatible with 11 mm(330181) or NSv(330980) series.
- Suffix ‑12‑00 stands for 12‑meter total system cable length. The sum of probe integral pigtail plus extension cable must equal 12 m exactly. Length mismatch will cause scale‑factor error and wrong measurement.
- Output signal connects to Bently 3500/42M, 3300 monitor racks or third‑party DCS for alarm, trip and trend logging.

Installation and Configuration Guide
Warning: Installation shall be performed by qualified instrumentation technicians. Always refer to original Bently Nevada 3300‑XL official manual as primary reference document.
- System‑Length Verification
- Calculate total cable length: probe integral pigtail + extension cable = exactly 12 m. Do not use shorter or longer cable assembly.
- Assemble Microdot connectors with manufacturer‑specified torque; power must be OFF while connecting / disconnecting transducer loop.
- Wiring & Cabinet Mounting
- Mount proximitor on standard DIN‑rail inside instrument cabinet.
- Connect negative DC power supply (‑23 ~ ‑30 VDC). Observe correct polarity.
- Route transducer coaxial cable separate from high‑power AC, contactor and VFD cables to reduce EMI interference. Respect minimum coaxial cable bending radius.
- Field Probe Gap Commissioning
- Adjust probe mechanical gap against shaft target. Target DC gap‑voltage working point near mid‑range (approx.‑10 VDC for AISI‑4140 steel).
- Lock probe lock‑nut firmly, re‑measure gap‑voltage to confirm no mechanical shift. Ensure operating point stays within linear zone (‑1 VDC ~ ‑17 VDC).
- Monitor Channel Setup
- Set monitor channel scale factor to 7.87 V/mm (200 mV/mil) for 8 mm 3300‑XL system.
- Configure alarm & trip thresholds per rotating‑machine OEM specification.
- Perform loop fault test: simulate probe open‑circuit to verify Not‑OK fault function triggers correctly.
- Maintenance & Troubleshooting
- Check Microdot connectors for dirt, corrosion and loose connection during unit turnaround.
- Monitor steady‑state DC gap‑voltage drift as health indicator of probe‑cable‑proximitor chain.
- Not‑OK fault: inspect probe tip damage, cable insulation break, connector defect or proximitor failure. Proximitor is non‑repairable on‑site; replace complete unit upon hardware failure.
- Hazardous‑Area Installation Notes
- For ATEX / IECEx hazardous‑location installation, strictly follow 3300‑XL intrinsic‑safety requirements for power supply, cable specification, grounding and enclosure rating.
Supplementary Remark
330180‑12‑00 is 12‑meter total‑length DIN‑rail proximitor for standard 3300‑XL 8 mm proximity system. Total physical transducer cable length must strictly match 12 m. It cannot pair with 11 mm or NSv probes/cables. Before commissioning, cross‑check part number, total system length and matching probe‑cable assembly against project BOM.
