Bently Nevada Proximity Probe - 330104-09-18-05-01-05

330104-09-18-05-01-05 Specification

▶Compressor Vibration Monitoring: Provides reliable shaft vibration measurement on centrifugal and axial compressors, particularly those operating in hazardous areas where ATEX/IECEx approvals are required.
▶Steam Turbine Thrust Position Monitoring: Monitors axial shaft position to detect thrust bearing wear, helping prevent catastrophic turbine damage.
▶Overspeed Protection Systems: Used as part of tachometer or overspeed detection systems
▶Generator Bearing Monitoring: The stainless steel armor provides additional cable protection in generator applications where cables may be exposed to high temperatures or physical abrasion.
▶Retrofit Installations: With its M10 x 1 thread and 5.0 meter total length, this probe is compatible with existing 3300 XL systems and can replace non-XL 3300 series 5 mm or 8 mm probes while maintaining interchangeability.

Q: What are the mechanical dimensions for this 330104-09-18-05-01-05 probe?
▶A: This probe has an overall case length of 180 mm (Option B) and an unthreaded length of 90 mm (Option A). The unthreaded length must be at least 20 mm less than the case length, which is satisfied (90 mm ≤ 160 mm).
Q: What is the total system length requirement for this 330104-09-18-05-01-05 probe?
▶A: This probe has a total length of 5.0 meters (Option C). It is designed for use with a 5 meter Proximitor sensor (e.g., 330180-50, -51, or -52). When used with an extension cable, the combined length of the probe and extension cable must equal the Proximitor sensor's total length.
Q: How does the armor on this 330104-09-18-05-01-05 probe benefit installation?
▶A: The flexible stainless steel armor (AISI 302 or 304 SST with FEP outer jacket) protects the probe cable from mechanical abrasion, sharp edges, and physical impact. This is particularly beneficial when routing cables through conduit, tight spaces, or areas with potential for wear.
Q: What is the minimum shaft diameter recommended for this 330104-09-18-05-01-05 probe?
▶A: The recommended minimum shaft diameter is 76.2 mm (3 in). For radial vibration or position measurements on shaft diameters smaller than this, the scale factor may change.
Q: Can this 330104-09-18-05-01-05 probe be used with the phenolic threaded mounting bracket?
▶A: Yes. The phenolic threaded mounting bracket (part number 27474-04) is available for M10 x 1 threads and is recommended when additional electrical isolation from the mounting location is required, such as in generator and electric motor bearing applications.
