Description
Product Overview
Part Number: 330180-51-05 Manufacturer: Bently Nevada (Baker Hughes) Product Series: 3300 XL Proximitor Sensor Type: Eddy current proximitor preamplifier, USA manufactured This 3300 XL proximitor is the signal conditioning module for 8mm (5/8″) 3300 XL proximity probe systems. It converts the eddy current gap signal from the probe into usable voltage output, used to monitor shaft radial vibration, thrust position and keyphasor signals for steam turbines, centrifugal compressors, generators and heavy process pumps. It works with Bently Nevada 3500 series monitoring racks, fully compliant with API 670 machinery protection standard. The ordering code 51 represents 5-meter total system cable length, suffix 05 indicates multi-agency approvals version.

Engineer Notes
- This proximitor is calibrated for a 5 meter total transducer system length. Sum of probe integral cable + extension cable must equal 5m, any mismatch will lead to scale factor error and inaccurate readings.
- Only compatible with 3300 XL 8mm probe family; cannot be used with 11mm, 25mm or NSv probe systems.
- Install on DIN rail inside control cabinet; keep away from high voltage power cables to reduce electrical noise interference.
- BNC input connector must be kept clean and capped when disconnected, avoid dust, moisture and pin damage.
- Do not modify internal circuit or wiring; unauthorized alteration will void calibration and warranty.
- Supports transducer OK fault detection, works with 3500/40, 3500/42 and related monitor modules.
- Suffix 05 version carries multiple safety agency approvals for petrochemical and power plant hazardous area applications.
Pre-Shipment Test Protocol
- Power supply loading test
- Scale factor and linearity calibration verification with standard gap target
- BNC connector continuity & insulation test
- Noise floor and signal stability inspection
- Visual inspection of housing, terminals, label and marking
- Agency certificate & datasheet review
- Anti-static & shockproof packaging inspection
Buyer FAQ
Q: Is 330180-51-05 new original? A: We supply brand new original Bently Nevada units, 12-month warranty, factory test certificate available on request.
Q: What does 51 stand for in part number? A: 51 = 5.0m total calibrated system length, DIN rail mounting version.
Q: What is the difference between 330180-51-00 and 330180-51-05? A: Electrical performance is identical. -05 variant includes multi-agency certifications required for many power and petrochemical site approvals.
Q: Can I mix different length probes and extension cables on this proximitor? A: No. The combined probe plus extension cable must equal exactly 5 meters total length.
