Description
Product Overview
Part Number: 330104-11-22-10-02-CN Manufacturer: Bently Nevada (Baker Hughes) Product Series: 3300 XL 8 mm Proximity Probe Type: Non-contact eddy current proximity probe, USA manufactured. This 8mm eddy current probe is used to measure shaft radial vibration, thrust displacement, shaft position and keyphasor speed signal for rotating machinery. Typical applications include steam turbines, centrifugal compressors, generators and large pumps. It works in conjunction with 3300XL proximitor and Bently 3500 monitoring rack to deliver real-time displacement data for machinery protection and predictive condition monitoring.

Engineer Notes
- This probe must be matched with the corresponding 3300XL proximitor, and total system cable length must comply with specification to guarantee scale factor accuracy.
- Standard installation gap target for 8mm 3300XL probe: approximately 1.25 mm, adjust gap during commissioning carefully.
- Target surface should be ferrous conductive steel; non-ferrous metal will change scale factor and reduce measurement precision.
- Do not impact, scratch or crack the PPS probe tip during mounting; physical damage causes measurement drift.
- CN suffix: China market certified version, electrical performance identical to standard 00 suffix variant.
- Cable splice, cut or unauthorized modification is forbidden; any alteration invalidates factory calibration and warranty.
- Follow recommended torque for probe thread installation, avoid over-tightening.
Pre-Shipment Test Protocol
- Continuity & insulation resistance test for probe and integrated cable
- Scale factor and linearity calibration test with standard steel target and precision gap gauge
- Noise floor and output signal stability inspection
- Full visual inspection: cable jacket, connector, probe tip and thread condition
- Part number, label and marking verification
- Calibration documentation review
- Anti-static & shock-resistant packaging check
