Description
Product Overview
Part Number: 330106-05-30-10-02-CN Manufacturer: Bently Nevada (Baker Hughes) Product Series: 3300 XL 8 mm Proximity Probe Type: Non-contact eddy current proximity probe, reverse mount design, armored triaxial integral cable, M10×1 metric thread, USA manufactured. This 8mm reverse mount eddy current probe is engineered for installation scenarios requiring backside mounting. It measures shaft radial vibration, thrust displacement, shaft position and keyphasor speed signals for rotating machinery including steam turbines, centrifugal compressors, generators and large process pumps. Paired with matched 3300XL proximitor and Bently 3500 monitoring rack, it delivers real-time displacement signals for machinery protection and predictive condition monitoring, compliant with API 670 standard.

Engineer Notes
- This reverse mount 8mm probe must be matched with the corresponding 3300XL 8mm proximitor. The total system cable length must strictly follow datasheet limits to preserve scale factor calibration accuracy.
- Recommended working gap for standard 8mm 3300XL probe: approximately 1.25 mm. Verify gap voltage during commissioning.
- Target surface must be ferrous conductive steel. Non-ferrous materials shift scale factor and degrade measurement accuracy.
- Protect PPS probe tip from mechanical impact and scratches; tip damage leads to unstable signal and measurement drift.
- CN suffix indicates China market certified version; electrical characteristics match standard 00 suffix model.
- Do not splice, cut or modify the factory armored integral cable. Unauthorized cable modification voids calibration and warranty.
- Control torque on M10 threads during installation; over-tightening may crack probe housing and damage internal components.
- Reverse mount structure allows installation from the rear side of the machine casing for limited front access.
Pre-Shipment Test Protocol
- Continuity & insulation resistance test of probe and attached armored integral cable
- Scale factor and linearity test with standard steel target and precision gap gauge
- Noise floor and output signal stability check
- Full visual inspection: armor jacket, connector, probe tip and thread condition
- Part number, label and marking verification
- Calibration document review
- Anti-static & shockproof packaging inspection
Buyer FAQ
Q: Is 330106-05-30-10-02-CN new original? A: We supply brand new original Bently Nevada units, 12-month warranty, factory calibration certificate available on request.
Q: What is reverse mount probe? A: Reverse mount probe means assembly is installed from the back of the mounting hole, suitable when front side of machine casing has no enough operation space.
Q: What monitoring system works with this probe? A: It pairs with Bently Nevada 3500 machinery protection rack and matching 3300XL 8mm proximitor.
Q: What does CN suffix mean? A: CN is Chinese market certification variant; all electrical parameters are identical to standard 00 version.
